When deciding to get a COVID-19 vaccine, it may help to understand the different vaccine technologies available. At least 40 vaccines against the SARS-CoV-2 virus (the cause of COVID-19 illness) are approved or authorized for use in at least 197 countries around the world. These vaccines have gone through extensive testing prior to government approval.
All of the COVID-19 vaccines can be grouped into categories based on how they are designed, including what is in them and how they teach your body to build immunity to the SARS-CoV-2 virus. These categories are also called vaccine technologies or vaccine platforms.
MYTH: The vaccines cause viral shedding or make you sick with COVID-19.
FACT: Vaccines that do not contain live viruses can’t cause viral illness. They can’t make you contagious or cause viral shedding, either.
