I received the Johnson & Johnson vaccine. With variants like Delta, do I need to get a booster with an mRNA vaccine (Moderna or Pfizer)?

At this time, the Centers for Disease Control and Prevention and the Wisconsin Department of Health Services do not recommend additional vaccination for people who have received the one-dose Johnson & Johnson vaccine. The vaccine provides strong protection from Covid-19, and in individuals who do experience breakthrough infection, the Johnson & Johnson vaccine helps protect against severe disease and hospitalization, rendering it similar to other types of respiratory illness. Evidence also suggests vaccinated people are unlikely to transmit the virus to others. UHS, along with other vaccine providers in the state, are not offering second doses of any vaccine to individuals who received the Johnson & Johnson vaccine. Please do not show up to the vaccine clinic to receive a second dose if you have received the Johnson & Johnson vaccine as staff will not be able to provide you with another dose. The university will continue to monitor related national and state guidance.
