COVID-19 Vaccine Information


On this page:


September 8, 2022 Booster Dose Update: The U.S. Food and Drug Administration (FDA) has authorized reformulated COVID boosters from Moderna and Pfizer that target the original strain of COVID-19 and today's most common strains. These updated COVID-19 boosters can both help restore protection that has decreased since previous vaccination and provide better protection against newer variants. The updated, or bivalent boosters, target the most recent Omicron subvariants that are more contagious and more resistant than earlier strains of the virus. The updated vaccines do not replace shots for the primary series, but they do replace the original booster people older than 12 receive.

Beginning September 21, 2022 WCHD will be able to provide the new updated booster to those 12 years old and above. We will not be offering COVID-19 vaccine boosters (original or updated boosters) to anyone 12 years and older at our vaccine clinics until September 21 when the updated vaccine is available.  We will continue to offer primary series vaccines (first and second doses) to anyone 6 months or older and booster doses to those aged 5 through 11. Please stay tuned to our website and Facebook page for updates.

For all other clinics please call the individual pharmacy or clinic.

How do we know that the COVID-19 vaccine is safe and effective?

Vaccine approval is driven by science. The Food and Drug Administration (FDA), the Centers of Disease Control (CDC,) and independent advisors review all vaccine safety and effectiveness data before any vaccine is approved or allowed for distribution. COVID-19 vaccines are going through all the same steps in the trial phases that all vaccines go through to get the full FDA vaccine license and approval.

During emergencies, like the COVID-19 pandemic, the FDA can issue an Emergency Use Authorization (EUA) to let people get a vaccine before all the trials are complete. The FDA will only give a COVID-19 vaccine an EUA if the current phase III trial data shows the vaccine is safe and has more benefits than risks. Like with all vaccines, after a COVID-19 vaccine is made available to the public, the FDA and CDC will continue to closely monitor the vaccine to help ensure any issues are immediately addressed.

COVID-19 vaccines were tested in large clinical trials to make sure they meet safety standards. Thousands of people were recruited to participate in these trials to see how the vaccines offer protection to people of different ages, races, and ethnicity, as well as those with different medical conditions.
