Vaccine 101

How does it work?

From the CDC:

COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19 without us having to get the illness. Different types of vaccines work in different ways to offer protection, but with all types of vaccines, the body is left with a supply of “memory” T-lymphocytes as well as B-lymphocytes that will remember how to fight that virus in the future.

It typically takes a few weeks for the body to produce T-lymphocytes and B-lymphocytes after vaccination. Therefore, it is possible that a person could be infected with the virus that causes COVID-19 just before or just after vaccination and then get sick because the vaccine did not have enough time to provide protection.

Sometimes after vaccination, the process of building immunity can cause symptoms, such as fever. These symptoms are normal and are a sign that the body is building immunity.

Are any of the vaccines FDA approved?

On Aug. 23, 2021, the U.S. Food and Drug Administration (FDA) approved the Pfizer vaccine.

Does it  give you the virus?

From Immunize Nevada:

No. None of the authorized and recommended COVID-19 vaccines or COVID-19 vaccines currently in development in the United States contain the live virus that causes COVID-19. This means that a COVID-19 vaccine cannot make you sick with COVID-19.

There are several different types of vaccines in development. All of them teach our immune systems how to recognize and fight the virus that causes COVID-19. Sometimes this process can cause symptoms, such as fever. These symptoms are normal and are a sign that the body is building protection against the virus that causes COVID-19.

Does it prevent you from getting the virus?

From SNHD:

Based on what we know about how vaccines work, experts believe that getting a COVID-19 vaccine may help keep you from getting seriously ill even if you do get COVID-19.

If I had coronavirus, should I still get the vaccine or do I have immunity?

From the CDC:

Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, vaccine should be offered to you regardless of whether you already had COVID-19 infection.

At this time, experts do not know how long someone is protected from getting sick again after recovering from COVID-19. The immunity someone gains from having an infection, called natural immunity, varies from person to person. Some early evidence suggests natural immunity may not last very long.

We won’t know how long immunity produced by vaccination lasts until we have more data on how well the vaccines work.

Both natural immunity and vaccine-induced immunity are important aspects of COVID-19 that experts are trying to learn more about, and CDC will keep the public informed as new evidence becomes available.

Why are we being ask to continue to wear a mask and social distance after receiving the vaccine?

From Immunize Nevada:

Stopping a pandemic requires using all the tools available. Vaccines work with your immune system so your body will be ready to fight the virus if you are exposed. Other steps, like covering your mouth and nose with a mask and physical distancing, help reduce your chance of being exposed to the virus or spreading it to others. Together, COVID-19 vaccination and following CDC’s recommendations to protect yourself and others will offer the best protection from COVID-19.

From SNHD:

Wearing a mask is still recommended during the pandemic. We do know that the vaccine has been shown to protect the people who receive it; however, we do not have enough information to know if it protects those who haven’t been vaccinated. It is important to continue to wear a mask that covers your nose and mouth when in contact with others outside your household, when you are in a health care facility, and when receiving any vaccine, including a COVID-19 vaccine. For more information, the Centers for Disease Control and Prevention (CDC) has more information at Considerations for Wearing Masks.

How long will the vaccine last/ be effective?

From SNHD:

We won’t know how long immunity lasts after vaccination until we have more data on how well COVID-19 vaccines work in real-world conditions.

Experts are working to learn more about both natural immunity and vaccine-induced immunity. CDC will keep the public informed as new evidence becomes available.

Experts also do not know what percentage of people would need to get vaccinated to achieve herd immunity to COVID-19 at this time. Herd immunity (community immunity) is a term used to describe when enough people have protection—either from previous infection or vaccination—that it is unlikely a virus or bacteria can spread and cause disease. As a result, everyone within the community is protected even if some people don’t have any protection themselves. The percentage of people who need to have protection in order to achieve community immunity varies by disease.
