If you have had COVID-19, you can receive a third dose of the vaccine as recommended for certain groups of people. This includes individuals aged 60 and older, residents of long-term care facilities, healthcare workers in contact with patients, and individuals with certain chronic conditions. It is important to wait until the appropriate time to receive the third dose, usually six months after your last dose. If you fall into one of these categories, you may be eligible for a third dose when the time comes. You can choose to receive the third dose even if you have already had COVID-19.
