Covid-19 Vaccine

The vaccine is now available for everyone six months and older. Visit vaccine.gov and your state’s health department website for more information.

Think of a vaccine as a way for your immune system to practice for an infection. Vaccines give the body a preview of a virus or bacteria before you get the real deal. The immune system then learns and remembers how to react. This helps the body stop the virus or bacteria from making you sick if you are exposed to it.

Current data suggest that COVID-19 vaccines authorized for use in the United States offer protection against most variants. However, some variants might cause illness in some people after they are fully vaccinated.

All persons ages six months and older are now eligible to receive the vaccine. Visit vaccine.gov and your state’s health department website for more information.

The COVID-19 vaccine gives your immune system a preview of the coronavirus, so it learns how to stop it. It triggers antibodies in your blood to attack the virus’s unique spike protein. (Did you know, coronaviruses got their name because they have protein spikes that look like a crown?)

Your immune system learns from the vaccine how to quickly recognize the actual virus and stop it from multiplying. The idea is to stop SARS-CoV-2, the virus that causes COVID-19, from getting into cells, replicating itself and making you sick.

Two doses of the Pfizer or Moderna vaccines are needed to provide the complete protection. The first one primes the immune system, helping it to recognize the virus, and the second one strengthens the immune response. If the vaccine you received requires two doses, you should receive both doses. You should also stay up to date on your COVID vaccines by receiving any recommended booster doses.

The single-dose Johnson and Johnson vaccine is also considered in some situations such as for people who are allergic to an ingredient in the Pfizer or Moderna vaccines.

No. None of the COVID-19 vaccines are made with a live virus. They cannot give you COVID-19.

Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, it is recommended everyone eligible get a COVID-19 vaccine-even if they have been sick with COVID-19 before. 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.

According to the CDC, those who are fully vaccinated will continue to be protected against serious illness and hospitalization. However, some study data suggests that immunity may decline over time after the primary series. Booster doses are recommended for optimal protection against the virus.

In November 2021, the FDA authorized a booster dose of the Pfizer-BioNTech COVID-19 vaccine and the Moderna COVID-19 vaccine for millions of Americans to be administered at least five months after their second dose of the Pfizer vaccine. Individuals who completed the Johnson & Johnson primary vaccine series should receive a booster at least two months after their initial vaccination.

The CDC recommends booster doses of the COVID-19 vaccine for those who are moderately or severely immunocompromised, with the number of booster doses dependent on age. Immunocompromised individuals aged 12 and older should receive a total of 5 doses of mRNA vaccine to be considered up to date. A complete schedule of COVID-19 booster doses for immunocompromised individuals is available on the CDC website: https://www.cdc.gov/coronavirus/2019-ncov/vaccines/recommendations/immuno.html

Yes, the vaccination is recommended for all people six months and older, including people who are trying to get pregnant, are pregnant, breastfeeding, or may become pregnant in the future. Data from thousands of people who are pregnant, breast-feeding and those who became pregnant after vaccination confirms that the COVID-19 vaccine is safe and effective before, during and after pregnancy.

In fact, the CDC has issued a health alert recommending those who are pregnant, recently gave birth, are breast-feeding, or trying to become pregnant receive a COVID-19 vaccine as soon as possible.

The CDC V-Safe data shows no increase in adverse outcomes in pregnant women who receive the COVID-19 vaccine. There is also no evidence linking vaccines to infertility. The risks of COVID-19 infection outweigh any known or potential risks of vaccination while pregnant or trying to conceive.

Pregnant women are at a higher risk to get ill with COVID-19 compared with non-pregnant women. A study was conducted before the Delta variant; results published by the Journal of the American Medicine Association showed pregnant women with COVID infection are 15 times more likely to die in hospital, 14 times more likely to require intubation and 22 times more likely to have a premature birth.

See the CDC’s COVID-19 Vaccines While Pregnant or Breastfeeding info page.

Yes. People who are immunocompromised are more likely to be hospitalized and get seriously ill from COVID-19. It’s recommended you get vaccinated if you are immunocompromised. These people may not get as much protection after two doses of the vaccine as do people with normal immune systems. For that reason, additional doses are now recommended, with the schedule varying by primary vaccine series.

If you are immunocompromised, discuss the vaccine with your doctor for a personalized recommendation. In addition, discuss with your doctor whether you should get a medication called Evusheld that will help provide additional protection against COVID-19.

The vaccines authorized are highly effective at preventing severe disease, death, and provide protection from the Omicron variant. The vaccines are not 100% effective, and some fully vaccinated people may experience illness. It’s important that as many people as possible get vaccinated to slow the spread of variants. Newer versions of the vaccine may be available in fall 2022 that will provide even better protection against the newer variants of COVID-19.

Omicron Variant: What You Need to Know

We are confident the COVID-19 vaccines are safe and effective with the FDA’s emergency use authorizations and now permanent approval of the Pfizer and Moderna vaccines. The vaccines passed numerous, required safety checks and study of reported side effects or adverse events. Several months of data have shown us the vaccines are safe and effective.

In clinical trials, Novavax was 90% effective against mild, moderate, and severe COVID-19 infection.

Novavax uses a more traditional method of generating an immune response than the other COVID-19 vaccines. The vaccine includes a protein from the virus itself to strengthen the immune response. This vaccine technology is like that used in flu or Hepatitis B vaccines.

The Pfizer-BioNTech and Moderna vaccines rely on newer mRNA technology. These vaccines deliver a set of instructions to cells, which then create pieces of COVID-19’s spike protein and generate corresponding antibodies.

The vaccine requires two doses three or four weeks apart, depending upon vaccine. Immunity takes some time to develop- at least two weeks after last the last injection. For example, someone vaccinated in late December won’t be fully protected until late January or early February. To be considered up to date on COVID vaccines, people should receive all recommended boosters.

Side effects are like other vaccines. The most common side effects are pain/redness at the injection site, headache, fatigue, muscle/joint aches and low-grade fever. The side effects respond well to Tylenol and ibuprofen. Most side effects last less than 24 hours and those ages 55 and older reporter fewer side effects.

Although the risk that fully vaccinated people could become infected with COVID-19 is lower than for unvaccinated people, any fully vaccinated person who experiences symptoms consistent with COVID-19 should isolate themselves from others, be clinically evaluated for COVID-19, and tested for COVID-19, if indicated. The symptomatic fully vaccinated person should inform their healthcare provider of their vaccination status at the time of care.
