Several COVID-19 vaccines have been developed. Vaccines are made by different companies. Each may have some differences from the others. So far, Pfizer-BioNTech, Moderna, and Janssen (Johnson & Johnson) vaccines are authorized for emergency use in the United States. Emergency use authorization (EUA) of additional COVID-19 vaccines is expected to continue through 2021. As the U.S. Food & Drug Administration meets and reviews other COVID-19 vaccines, the agency will provide updates on vaccines authorized for emergency use. When new details become available, Tuolumne County Public Health will update the information provided on this website.
The Centers for Disease Control and Prevention (CDC) has information about the vaccines undergoing large-scale trials. Most of the vaccines in these trials require two doses. The first shot starts building protection. A second shot 3-4 weeks later adds to the protection and provides maximum effectiveness.
If you tested positive for COVID-19 and recovered, you should still get the vaccine. While there is likely some immunity following recovery lasting at least a few weeks, it is unclear how long that immunity lasts and how much protection you get. The CDC recommends waiting 90 days after recovering from COVID-19 to be vaccinated.
Any individuals in the community who have had a known COVID-19 exposure should not get vaccinated for COVID-19 until their quarantine period has ended to avoid potentially exposing healthcare professionals and other persons to the virus during their vaccination visit.
As the vaccines become available, you will still need to wear a mask and practice social distancing until enough people have been vaccinated and the virus gets under control. Vaccines have been shown to prevent infection. Studies are pending to see whether vaccines prevent spread of COVID-19.
