UPDATE ON JOHNSON & JOHNSON VACCINE: The U.S. Food and Drug Administration is limiting the use of Johnson & Johnson's (J&J) COVID-19 vaccine. Though the potential benefits of the vaccine outweigh the risks, the FDA said last week that it is restricting the use of the J&J vaccine. It will be limited to individuals 18 and older and medically ineligible for another approved vaccine and to those who only have access to the J&J vaccine and want one, according to an FDA news release. Researchers with the FDA and Centers for Disease Control and Prevention found that the vaccine resulted in 60 confirmed cases of thrombosis with thrombocytopenia syndrome.


ADDITIONAL BOOSTER DOSES APPROVED: The Wisconsin Department of Health Services (DHS) has recently approved the new CDC guidelines on second booster doses for certain individuals. The Winnebago County Health Department will provide these additional doses for those individuals that qualify. You can receive a second booster dose of:

  • The Pfizer COVID-19 vaccine or Moderna COVID-19 vaccine if you are aged 50 years and older and it has been at least 4 months after receiving the first booster dose of any authorized or approved COVID-19 vaccine.
  • The Pfizer COVID-19 vaccine if you are 12 years of age and older and are immunocompromised and it has been at least 4 months after receiving the first booster dose of any authorized or approved COVID-19 vaccine. These are people who have undergone solid organ transplantation, or who are living with conditions that are considered to have an equivalent level of immunocompromise.
  • The Moderna COVID-19 if you are 18 years of age and older and it has been at least 4 months after the first booster dose of any authorized or approved COVID-19 vaccine with the same certain kinds of immunocompromise.
  • An mRNA COVID-19 vaccine if you are aged 18-49 years old and are not moderately or severely immunocompromised and received the Johnson & Johnson COVID-19 vaccine as both their primary series dose and booster dose and it has been at least 4 months after their first Johnson & Johnson booster dose.



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. Currently, both the Pfizer and Moderna Vaccines are FDA approved.

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.
