Can A COVID-19 Vaccine Make Me Sick With COVID-19?
  • Because none of the authorized COVID-19 vaccines in the United States contain the live virus that causes COVID-19, the vaccine cannot make you sick with COVID-19, or make you Test positive.
  • The Pfizer and Moderna vaccines do not contain any live virus. Instead, they work by teaching our cells to make a harmless piece of a “spike protein,” which is found on the surface of the virus that causes COVID-19. After making the protein piece, cells display it on their Our immune system then recognizes that it does not belong there and responds to get rid of it. When an immune response begins, antibodies are produced, creating the same response that happens in a natural infection.
  • You should get a COVID-19 vaccine even if you already had COVID-19. Getting sick with COVID-19 offers some protection from future illness with COVID-19, sometimes called “natural” The level of protection people get from having COVID-19 may vary depending on how mild or severe their illness was, the time since their infection, and their age; and no currently available test can reliably determine if you are protected after a COVID-19 infection.
CDC is shortening the recommended time for isolation from 10 days for people with COVID-19 to 5 days
  • If asymptomatic, followed by 5 days of wearing a mask when around
  • The change is motivated by science showing that the majority of SARS- CoV-2 spread occurs early in the course of illness, generally in the 1-2 days before symptoms begin and the 2-3 days
