Who needs an additional COVID-19 vaccine?
Currently, CDC is recommending that moderately to severely immunocompromised people receive an additional (third) dose. This includes people who have:

  • Been receiving active cancer treatment for tumors or cancers of the blood
  • Received an organ transplant and are taking medicine to suppress the immune system
  • Received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system
  • Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • Advanced or untreated HIV infection
  • Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response

People should talk to their healthcare provider about their medical condition, and whether getting an additional dose is appropriate for them.

COVID-19 Booster Shots
On August 18, 2021, U.S. Department of Health and Human Services (HHS) announced a plan for offering booster shots for all Americans beginning this fall and starting 8 months after an individual’s second dose. Check back here for more specifics on when booster shots will be available in our community.

Once you have scheduled your first dose appointment, we will contact you via text message or phone call with your 2nd appointment date and time (if applicable).

Currently eligibility to receive the COVID-19 Vaccine is limited to persons at least *18 years of age that either live or work in the state of Illinois.

(*Note: Only the Pfizer vaccine has been approved for individuals 12 years of age and older. The Moderna and one-dose Johnson & Johnson vaccines are approved for individuals 18 years of age and older.)

CGH COVID-19 Vaccination Plan for the Public/FAQs

Below is a list of common, Frequently Asked Questions (FAQs) that we have received about the vaccine. (For a printable copy of our CGH COVID-19 Vaccination Plan for the Public/FAQs, click here.)

Should I continue to seek out other opportunities to receive the vaccine?

Yes. At a minimum, contact your local health department. As stated above, currently the distribution of the vaccine is under the control of the State of Illinois and the local health departments. We encourage you to get the vaccine where it is first available to you. In some cases, that may be from your local county health department.

Local pharmacies such as Walgreens and CVS are expected to receive vaccine sometime as well. At this point, we have no information about if/when that would happen.

What will be the process of getting the vaccine from CGH?

CGH vaccines are currently being given in the Ryberg Auditorium at the hospital. The whole process shouldn’t take very long. You will need to check in, and your information will be verified. You will be shown to a vaccination station that is staffed by CGH nurses. After the vaccine is given, you will need to be observed for 15 minutes (30 minutes in special circumstances). More specific instructions will be given at the time your appointment is scheduled.

Which vaccine will I be receiving? How many doses will I need?

Currently, there are two companies producing the vaccine: Pfizer and Moderna. More than likely, you will be receiving the Moderna vaccine that is a two-part vaccine given roughly 28 days apart.

If I receive the Moderna vaccine for my first injection, can I get the Pfizer vaccine for the second?

No. Both doses must be from the same brand.

What are the side effects to the vaccine?

Mild side effects are common and may include: soreness in the arm receiving the injection, muscle aches, fevers, chills, headaches and fatigue. These usually are an indication that your immune response is working. SEVERE side effects, thankfully, are NOT COMMON.

The growing experience with the vaccine is showing that the older you are, the less side effects you tend to have (one of the few advantages to being older!). Concerns about side effects are valid but please balance that with the risk of COVID itself.

Should I take Ibuprofen or Tylenol before or after I get the vaccine?

We do not recommend taking ibuprofen or Tylenol before getting the vaccine. However, for mild symptoms, if needed, you may take them afterward.

How much will the vaccine cost?

Your insurance will be billed for the administration, but not for the vaccine itself. The vaccine is free of charge. You may receive an Explanation of Benefits (EOB) stating you have an out-of-pocket expense, but you should not be billed for this. If for some reason you do receive a bill, please contact the business office and we will take care of it.

If I had COVID in the past or tested positive previously, can I still get the vaccine?

Yes, if you have recovered and have been released from quarantine (at least 10 days from the onset of symptoms).

If I’m allergic to the flu vaccine, can I still get the COVID vaccine?

Yes. But you will need to be observed for 30 minutes following.

If I have a history of anaphylaxis or other severe allergies and carry an Epi-Pen with me, can I still get the vaccine?

Yes, but you will need to be observed for 30 minutes following. Please bring your Epi-Pen with you.

If I have an allergy to antibiotics, can I still get the vaccine?

Yes. If it was a severe reaction in the past, you will need to be observed for 30 minutes afterward.

If I am currently taking antibiotics, can I still get the vaccine?

Yes, as long as you do not have symptoms of COVID. Please speak with your physician or health care provider first if you have any questions.

I recently got my shingles or pneumonia vaccine. Can I get the COVID vaccine now?

Yes, as long as it has been 14 days since you received any other vaccine.

If I don’t live in Whiteside County, can I still get the vaccine through CGH?

Yes, as long as you live or work in the state of Illinois. Again, we encourage you to contact your local county health department as well.

We strive to do our best for you every day. This whole pandemic has been difficult for everyone and we appreciate your patience and support. Keeping you healthy is our primary concern. Please let us know if you have any other questions or concerns. With the COVID vaccine, we hope to see an end to this historic pandemic. Thank you for your help!

12-16-20 - COVID-19 Vaccine Arrives at CGH Medical Center

The COVID-19 vaccine has arrived at CGH Medical Center! This is a light at the end of a VERY long tunnel for our healthcare workers and our community. Matt Hammer, PharmD, Director of CGH Pharmacy (center), receives the vaccine shipment from Emily Davy Gonzalez, Infectious Disease RN, Whiteside County Health Department and Whiteside County Sheriff John Booker.

While not all the counties in Region 1 are receiving allocations of vaccine, the vaccine is being utilized in the Region to reach healthcare workers and long term care residents that are most at risk as part of the Phase 1a vaccine distribution. As more vaccine becomes available, additional shipments of vaccine will be allocated to continue to meet the priority group populations in additional areas of the region. Please watch for additional information.

The Northern Illinois Rockford Region 1 includes Boone, Carroll, DeKalb, Jo Daviess, Lee, Ogle, Stephenson, Whiteside, and Winnebago Counties.

12-16-20 - COVID 19 Vaccines Have Arrived in Region 1

Local health departments in Region 1 are announcing that a limited supply of COVID-19 vaccine has arrived to the Region. While not all the counties in the Region are receiving allocations of vaccine, the vaccine is being utilized in the Region to reach healthcare workers and long term care residents that are most at risk as part of the Phase 1a vaccine distribution. As more vaccine becomes available, additional shipments of vaccine will be allocated to continue to meet the priority group populations in additional areas of the region.

12-11-20 - COVID-19 Drive Thru Testing Site

The State of Illinois is sponsoring a drive-thru, mobile testing site in Whiteside County on Saturday, December 19th and Sunday, December 20th at the Northland Mall, 2900 E. Lincolnway Sterling, IL 61071, East Parking Lot (old JCPenney).
Testing runs 8AM to 4PM each day and is free to anyone with no appointment necessary.
Testing is an important part of finding cases to stop the spread of COVID-19 in our communities and lower our positivity rate.

12-11-20 - Region 1 Vaccine Delivery

Local health departments in Region 1 are expecting a limited amount of COVID-19 vaccine to be delivered to the region next week. While adults should be able to get vaccinated in 2021, a limited amount of vaccine will be available in Region 1 in 2020. Healthcare workers who treat COVID-19 patients and older adults living in long-term care facilities will receive the vaccine first. As additional vaccine becomes available, your Local Health Department will allocate vaccine based on risk of serious illness and prevention of the spread of COVID-19 in the community. Plans are in progress for getting more vaccine out to the community. The public should know that at this time there is no waiting list or appointment list to receive a COVID-19 vaccine. Check your local health department’s social media and website for updated information as this is a rapidly changing situation.

12-10-20 - FDA Briefing Document Pfizer-BioNTech COVID-19 Vaccine

On November 20, 2020, Pfizer and BioNTech (the Sponsor) submitted an Emergency Use Authorization (EUA) request to FDA for a COVID-19 vaccine intended to prevent COVID-19 caused by severe acute respiratory syndrome coronavirus 2. Click here to read the FDA Briefing Document that includes safety and efficacy data from ongoing phase 3 trials.

12-9-20 - From Dr. Eric Kuhns

The first full day of immunizations in England brought about 2 significant allergic reactions. These were both in people who had allergies bad enough to have Epipen prescriptions. There was not a signal for this in the Pfizer trial, and so far seen in only two people. For the time being, those with a history of severe allergic reactions (i.e. requiring you to carry an Epipen or similar rescue medication) are being asked to hold off in England. There are likely ways to mange this if it becomes a significant issue - we will follow this.

Vaccine Availability

When will a vaccine be available?

Vaccines are currently available in limited quantities and the distribution of the vaccine is under the control of the State of Illinois and the local health departments.

Manufacturing capacity has already been developed for some vaccines and vaccine distribution systems are being put in place. However, because of limited quantities of vaccine, some groups of people will be offered the vaccine first, likely health care workers, other essential personnel, and those most vulnerable to severe disease and death.

Where can I get the vaccine?

There are currently multiple locations to obtain the vaccine. To locate local vaccines, visit

Will the state (or federal government) establish mass immunization programs, like they did in the 1960’s?

Illinois is working with local health departments and providers across the state to provide COVID-19 vaccinations that resemble larger versions of yearly flu clinics, rather than the mass vaccination activities of the past.

My family member was offered a vaccine through their employer. Why can’t the rest of my family get the vaccine?

Because vaccine will be very limited when it first comes out, administration will be limited to those identified in prioritized (high-risk) groups. This is to ensure that all individuals in the high-risk groups are able to receive the vaccine. As more vaccine becomes available, those groups eligible to receive the vaccine will expand.

Is there a scheduled date for distribution per phases?

Effective April 12, 2021 in Illinois, the vaccine is available to all persons aged 16 and over* (depending on the vaccine brand). Currently, the only vaccine approved for persons aged 16-17 years old is the Pfizer vaccine.

Will distribution of vaccine be divided per capita?

Vaccine will be distributed according to the population of each county, adjusted to ensure health equity by weighting according to the COVID-19 Community Vulnerability Index (CCVI).

What about one municipality that has very high numbers within an otherwise lower number county? (in reference to prioritizing vaccine distribution)

Distribution within counties will be overseen by local health departments. IDPH will work with LHDs to ensure providers have adequate amounts of vaccine to support the municipalities/communities they serve.

How many shots of the Covid-19 vaccine will be needed?

Moderna and Pfizer require two shots to be effective. The Johnson & Johnson vaccine uses one shot, but is currently on pause with the CDC and FDA. At this point, research is being conducting to determine if and when a booster dose will be needed.

I understand the vaccination requires two shots. What if I am unable (or do not want) to get a second shot?

If you choose not to get a second dose, you may reduce the effectiveness of the vaccine. The first dose of the vaccine will provide some protection, but the recommendation is to receive two doses to be protected as intended.

What happens if they run out of the vaccine before I get my second shot?

CDC is structuring shipments in such a way that 21 or 28 days after the first shipment, the same number of doses will be shipped, so providers will have enough vaccine for a second dose. The 21- or 28-day requirement between doses is a minimum requirement, not a maximum. If, for some reason, you are unable to receive the second dose at the recommended interval, you can receive the second dose at a later date.

Who besides healthcare workers will be able to administer the vaccine? For example, we recently passed a law allowing dentists to administer flu shots. Will dentists, pharmacists and other qualified professionals, besides doctors and nurses, be able to administer the vaccine?

IDPH licenses EMTs and CNAs. All other healthcare professionals including but not limited to doctors, nurses, pharmacists, and dentists are licensed by the Illinois Department of Financial and Professional Regulation (IDFPR).

It is the decision of IDFPR as to who may or may not administer a vaccination within their scope of practice and determine how they will modify their scopes of practice to allow for additional vaccinators. Currently dentists, pharmacists and pharmacy technicians have had their scope of practice extended by IIDFPR to allow them to administer the COVID-19 vaccine when it becomes available. IDPH has issued recommendations to allow EMT’s at the advanced and intermediate levels to administer vaccine, as long as their Medical Director for their EMS system follows certain guidelines.

Vaccine Requirements/Mandates

Do I have to get a COVID-19 vaccine?

There is no federal or state mandate to receive the COVID-19 vaccine.

Can my employer require that I receive a COVID-19 vaccine before returning to work?

Decisions regarding immunization at private workplaces are up to the employer.

Are schools requiring students to receive a COVID-19 vaccine, similar to mumps and measles? Will restrictions be placed on my child if we refuse to vaccinate?

There is no requirement for students to receive the COVID-19 vaccine at this time. Currently, a pediatric vaccine is not available, and it may be some time before one is approved and becomes available.

What happens if I refuse to get vaccinated?

There are no legal repercussions (such as fines, sanctions or punishments) for refusing the vaccine. If you do not get vaccinated, you will not be protected against the virus that causes COVID-19 and will be more likely to be infected with the virus. Additionally, you will be at risk of transmitting this deadly virus to loved ones and other community members.

Do I need a vaccine if I have already had COVID-19?

When people recover from some viral infections, such as measles or mumps, they are protected against reinfection and would not need to be vaccinated. However, for other diseases, such as pneumococcal pneumonia or influenza, it is important to be vaccinated (or revaccinated) despite having disease because the vaccine protects against several strains or types of the pathogen and thus can still be valuable.

We are still learning about COVID-19. At this time, there is not enough information available to say if or for how long after infection someone is protected from getting COVID-19 again; this is called natural immunity. More studies are needed to better understand how long natural immunity lasts with COVID-19.

Do I have to get both the flu vaccine and the COVID-19 vaccine?

Yes, it is very important to get the influenza vaccine, particularly this season when both influenza viruses and SARS-CoV-2 will infect people. A seasonal flu vaccine will not protect you from COVID-19. Being infected with both the flu and COVID-19 at the same time, could lead to a more severe illness, which is why it is more important now than ever to get the flu vaccine.

Reducing the number of people who get severe influenza and require hospitalization will also help ensure that the health care system, hospitals and intensive care units will not be overwhelmed should there be an increase in Covid-19 cases this fall and winter.

Vaccine Safety

Is a COVID-19 vaccine safe?

The U.S. vaccine safety system ensures all vaccines are as safe as possible. Safety is a top priority. Currently, clinical trials are evaluating investigational COVID-19 vaccines with many thousands of study participants to generate scientific data and other information for the FDA to determine their safety and effectiveness.

If the FDA determines a vaccine meets its safety and effectiveness standards, it can make these vaccines available for use in the U.S. by approval or Emergency Use Authorization (EUA). After the FDA makes its determination, ACIP will review the available data in order to make vaccine recommendations to the CDC. ACIP will then recommend vaccine use. After a vaccine is authorized or approved for use, vaccine safety monitoring systems will watch for adverse events (possible side effects). CDC is working to expand safety surveillance through new systems and additional information sources, as well as enhancing existing safety monitoring systems.

Clinical Trials:

Phase 1 clinical trials assess the safety and dosage of a vaccine in a small number of people, typically a dozen to several dozen healthy volunteers. Whether a vaccine stimulates immune responses is often assessed in a phase 1 study but this is better assessed in phase 2 studies, which typically involve hundreds of people including some special groups such as children, people with pre-existing conditions such as heart disease, and older adults. Vaccine safety is also assessed in phase 2 studies, in which adverse events not detected in phase 1 trials may be identified because a larger and more diverse group of people receive the vaccine. However, only in much larger phase 3 clinical trials can it be demonstrated whether a vaccine is actually protective against disease and safety is more fully assessed.

Phase 3 clinical trials often include thousands of volunteers, and for Covid-19 vaccines will involve tens of thousands (30,000 to 45,000 people in some of the ongoing phase 3 trials). In phase 3 trials, participants are randomized to receive either the viral vaccine or a placebo vaccine (sometimes a vaccine against another disease or a harmless substance like saline). Randomization is a process to determine who receives the vaccine and who receives the placebo without any bias, like flipping a coin. To further prevent any bias in interpreting the study data, participants and most of the investigators will not know if an individual received the vaccine or placebo. The participants are then followed to see how many in each group get the disease. If the vaccine is efficacious, many fewer people who received the viral vaccine will get the disease compared to those who received the placebo vaccine. It takes time for cases of disease to accumulate so that we can be confident there is a true difference between the two groups, and this is why these phase 3 trials often take a long time. Assessing safety is also a major goal of phase 3 trials, both short-term safety (e.g. fever, tenderness, muscle aches) and long-term safety (e.g. autoimmune conditions or enhanced disease following infection).

After a vaccine is approved and in more widespread use, it is critically important to continue to monitor for both safety and effectiveness. Some very rare side effects may only be detectable when large numbers of people have been vaccinated. Safety concerns that are discovered at this late stage could lead a licensed vaccine to be withdrawn from use, although this is very rare.

Are the vaccines safe and if so, why have the pharmaceutical companies been indemnified? Are vaccine makers usually indemnified?

The FDA will make the determination on safety when they are deciding whether or not to approve the EUA.

What have the trials revealed?

Through their respective clinical trials, Pfizer and Moderna have indicated their vaccines are approximately 95% effective.

Information gathered through clinical trials becomes public in the course of the EUA submission. Once the EUA is submitted, these documents become accessible by the public through the FDA.

What is an emergency use authorization?

Drugs and vaccines have to be approved by the Food and Drug Administration (FDA) to ensure that only safe and effective products are available to the American public. In situations when there is good scientific reason to believe that a drug is safe and is likely to treat or prevent disease, the FDA may authorize its use even if definitive proof of the efficacy of the drug is not known, especially for diseases that cause high mortality.

Emergency use authorizations were granted by the FDA Commissioner for chloroquine and hydroxychloroquine (later revoked) and for the use of convalescent plasma to treat hospitalized patients with Covid-19. Many are concerned that Emergency Use Authorization for a vaccine could be issued prematurely, before sufficient safety and efficacy data have been generated through phase 3 clinical trials.

It is important to emphasize that the bar for ensuring safety of a vaccine is higher than for a therapeutic to treat an ill person. Vaccines are given to potentially millions of healthy people, unlike drugs for sick people, and loss of trust in a vaccine for SARS-CoV-2 could spill over into loss of trust in other vaccines, seriously jeopardizing public health.

Can someone get COVID-19 from the vaccine?

No, it is not possible to get Covid-19 from vaccines. Vaccines against SARS-CoV-2 use inactivated virus, parts of the virus (e.g. the spike protein), or a gene from the virus. None of these can cause Covid-19.

Can I get a COVID-19 vaccine if I am pregnant?

After the FDA’s decision on an EUA, ACIP will make recommendations for who should be vaccinated. ACIP will review data from clinical trials and determine if it is safe for pregnant women or other population groups to receive the vaccine.

Can children get a COVID-19 vaccine?

Pfizer is currently the only vaccine approved for children 12 years of age and older.

When injected with the vaccine, are you injecting me with COVID-19?

No, you are not being injected with the virus that causes COVID-19. None of the early COVID-19 vaccines tested in the U.S. use a live virus that causes COVID-19. The goal for each vaccine is to teach our immune systems how to recognize and to fight the virus that causes COVID-19. At this time, the vaccines closest to receiving approval are mRNA - messenger ribonucleic acid - vaccines. Like other vaccines, mRNA vaccines work by training the immune system to recognize a virus threat and begin producing antibodies to protect itself.

After getting a flu shot, I always get the flu. Will this cause me to get COVID-19?

Some people develop flu-like symptoms, such as mild fever and muscle aches, after getting a flu vaccination. These symptoms are not the same as having influenza. Similar to the flu vaccine, you may experience a sore arm, mild fever, and muscle aches, but you will not get COVID-19 from the vaccine.

I have allergies. Is this vaccine safe for me?

Individuals that have a severe allergy to polyethylene glycol (a component of laxatives and bowel prep) should not receive the Moderna or Pfizer vaccines.

What are the side effects of this vaccine?

When the vaccine manufacturers submit a request for an EUA, data from their clinical trials will be shared and we will know more about any potential side effects. At this time, studies have shown few people have side effects and those who do have very mild ones that include a sore arm, mild fever, and muscle aches.

After a vaccine is authorized or approved for use, many vaccine safety monitoring systems are in place to watch for adverse events (possible side effects). This continued monitoring can identify adverse events that may not have been seen during clinical trials. If an unexpected adverse event is observed, experts quickly study it further to assess whether it is a true safety concern.

It took four years to develop the mumps vaccine, how can the COVID-19 vaccine be safe and thoroughly tested so quickly?

The world’s attention has been on COVID-19 this year. Because financial and time resources have been dedicated to finding a COVID-19 vaccine, it was able to be developed quicker than vaccines in the past. These current COVID-19 vaccines under consideration were required to go through the same clinical trials and safety reviews as previously developed vaccines. The FDA issued guidance on the steps required for developing and ultimately licensing vaccines to prevent COVID-19 – the same rigorous safety standards required for all vaccines and all of the required steps were met.

Traditionally, it has taken many years to develop a vaccine, confirm its safety and efficacy, and manufacture the vaccine in sufficient quantities for public use. This timeline is substantially shortened for SARS-CoV-2 vaccines in development. There are several ways this has been made possible. First, some clinical trials have combined phases 1 and 2 to assess safety and the immune responses. Second, because of the high number of new cases of Covid-19 in many places, differences in disease risk between those who received the viral vaccine and those who received the placebo or comparison vaccine can be measured more quickly than in the absence of a pandemic. Third, the United States government and others have heavily invested in building the manufacturing capacity to produce large numbers of vaccine doses before the findings of the phase 3 trials are available. Typically, vaccine manufacturers wait until the phase 3 trial is completed and shows safety and efficacy before making such a large investment in manufacturing capacity. None of these factors that contribute to the accelerated development of a vaccine for SARS-CoV-2 imply that safety, scientific or ethical integrity are compromised, or that short-cuts have been made.

How long will the vaccine protect me from COVID-19?

Generally, you are considered fully vaccinated after 2 weeks of the completion of your vaccine (2 doses of Moderna or Pfizer, 1 dose of Johnson & Johnson).

Can I get COVID-19 after the first dose of the vaccine?

Although the first dose of vaccine offers some immunity, you will still be considered susceptible to COVID-19. The first dose of the vaccine will provide some protection, but the recommendation is to receive two doses to be protected as intended. Pfizer and Moderna have indicated their vaccines are approximately 95% effective.

Is this vaccine preservative free?

Yes. The vaccine candidates that are likely to be the first offered are preservative free.


Is a COVID-19 vaccine a guarantee that I will not get the virus?

Like any vaccine, there is no guarantee that you won’t get the virus, but early indications are the vaccines under consideration are 90%-95% effective in protecting against COVID-19. In addition, the vaccine offers protection against serious disease.

How many people need to get vaccinated to have herd immunity to COVID-19?

The percentage of people who need to have protection in order to achieve herd immunity varies by disease. Experts do not know what percentage of people would need to get vaccinated to achieve herd immunity to COVID-19. Some experts feel that 60-70% of the general population must be vaccinated to achieve herd immunity.

What are the vaccine recommendations for children under age 16?

None are currently approved for use, but are expected in the near future.

If I get the vaccine, can I quit wearing a mask and social distancing?

At this time, we are asking the public to continue wearing masks and practice physical distancing even if they have received the vaccine until a large proportion of the population is vaccinated and we are sure the vaccine provides long-term protection. As we learn more about immunity and the vaccine is widely available, this could change, but we are not at that point yet.

What entity will be paying for the vaccines?

The US Department of Health & Human Services (HHS) will absorb the cost of the vaccines.

Can the State purchase more?

There is no cost to the State for the vaccine. The federal government, through HHS and the CDC, oversees the allocation of vaccine to states.

How much will this vaccine cost me? Is it covered by my insurance?

There is no cost for the vaccine. However, vaccination providers will be able to charge an administration fee for giving the shot. Vaccine providers can get this fee reimbursed by the patient’s public or private insurance company or, for uninsured patients, by the Health Resources and Services Administration at the US Department of Health and Human Services.

Will the administrative fees be passed on to the patient in the form of a co-pay or deductible?


How do vaccines work?

Vaccines stimulate the human body’s own protective immune responses so that, if a person is infected with a pathogen, the immune system can quickly prevent the infection from spreading within the body and causing disease. In this way, vaccines mimic natural infection but without actually causing the person to become sick.

For SARS-CoV-2, antibodies that bind to and block the spike protein on the virus’s surface are thought to be most important for protection from disease because the spike protein is what attaches to human cells, allowing the virus to enter our cells. Blocking this entrance prevents infection.

Not all people who are infected with SARS-CoV-2 develop disease (Covid-19 is the disease caused by the virus SARS-CoV-2). These people have asymptomatic infection but can still transmit the virus to others. Most vaccines do not completely prevent infection but do prevent the infection from spreading within the body and from causing disease. Many vaccines can also prevent transmission, potentially leading to herd protection whereby unvaccinated people are protected from infection by the vaccinated people around them because they have less chance of exposure to the virus.

What are the different types of vaccines in development and why are there so many?

Several different types of vaccines against SARS-CoV-2, the virus that causes the disease Covid-19, are in development. Some are based on traditional methods for producing vaccines and others on newer methods. One of the more traditional ways of making a viral vaccine is to inactivate (kill) the virus with chemicals, such as is done with the flu vaccine, inactivated polio or hepatitis A vaccines, so that the virus can no longer multiply. Several inactivated SARS-CoV-2 vaccines are in development. Other vaccines are based on just a part of the bacteria or virus, typically one or more proteins, such as the vaccines for whooping cough (pertussis) and hepatitis B virus. For SARS-CoV-2 vaccines that focus on a part of the virus, this often means the spike protein on the surface of the virus.

Newer vaccine types include what are called viral vector vaccines, in which the SARS-CoV-2 gene for the spike protein is inserted into another harmless virus to deliver the gene to human cells where the spike protein is produced. The spike protein then stimulates immune responses. The most common viral vectors are adenoviruses, which typically cause common cold-like symptoms in people but are further weakened for vaccines so they cannot cause any disease at all. Several adenovirus vector vaccines for SARS-CoV-2 are in advanced clinical testing (phase 3 clinical trials).

Finally, instead of using a viral vector, the gene for the spike protein can be used directly as a vaccine in the form of DNA or messenger RNA (mRNA). These are the most novel SARS-CoV-2 vaccines. Several mRNA vaccines are in advanced clinical testing.

Many manufacturers around the world are working on this global problem. This means that there will likely be multiple different types of SARS-CoV-2 vaccines and they may work differently in different people. Hopefully, some will work well in older adults and in people with underlying conditions that impair their immune system, as these groups are more likely to get sick and die from Covid-19.
