About the COVID-19 Vaccine

Stopping a pandemic requires using all the tools we have available. Vaccines work with your immune system so your body will be ready to fight the virus if you are exposed. Other steps, like wearing masks and social distancing, help reduce your chance of being exposed to the virus or spreading it to others. 

Together, being vaccinated for COVID-19 and following the Center for Disease Control and Prevention’s (CDC) recommendations to protect yourself and others will offer the best protection from COVID-19. If you receive the vaccine, you significantly reduce your body’s ability to host the virus, thus slowing the spread.  At approximately 95 percent efficacy, the COVID-19 vaccine is extraordinarily effective at protecting you from the virus.  

Vaccines Available Or In Development 

There are several manufacturers that are working on the development of a COVID-19 vaccine. However, in the United States, only two have been approved by the Food and Drug Administration (FDA) for Emergency Use Authorization (EUA), a mechanism to facilitate the availability and use of medical countermeasures, including vaccines, during public health emergencies, such as the COVID-19 pandemic. 

The currently approved vaccines are:

  • Pfizer-BioNTech COVID-19 vaccine. This is the first vaccine that was approved by the FDA for EUA and is a two-dose regimen. After the first dose is administered, the second dose is administered in 21 days and must also be the Pfizer-BioNTech vaccine. The individual cannot receive a second dose from a different manufacturer. Learn more in this fact sheet. 
  • Moderna COVID-19 vaccine. This is the second vaccine approved by the FDA for EUA. After the first dose is administered, the second dose is administered in 28 days and must also be the Moderna vaccine. The individual cannot receive a second dose from a different manufacturer. Learn more in this fact sheet.

AstraZeneca is also working on a COVID-19 vaccine that is expected to be submitted for FDA EUA in the United States in early 2021. The AstraZeneca COVID-19 vaccine is also a two-dose regimen with the second dose administered 28 days after the first dose. 

Johnson & Johnson is expected to seek FDA EUA for the company’s COVID-19 vaccine in February 2021. The Johnson & Johnson vaccine is a single-dose regimen, and if approved, would be the only single-dose vaccine currently available. 

At this time, we do not know if additional boosters or an annual vaccine will be necessary. 

If You’ve Already Tested Positive For COVID-19

Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, we encourage you to get a COVID-19 vaccine even if you have previously had COVID-19. However, since current evidence suggests you have some natural immunity to reinfection within 90 days, we ask that you choose to defer vaccination until 90 days have passed from the time you tested positive for the virus. More vaccine is coming, so we anticipate that you will be able to receive the vaccine at a later date.
