It is recommended that the next dose of COVID-19 vaccine be given at least 6 months since your last vaccine dose or last COVID-19 infection, as it produces a potentially higher and longer immune response. Some individuals, due to their unique health status and personal situation, may choose to get the vaccine earlier than the recommended interval of 6 months. The earliest the vaccine can be received is at a 3-month interval since your last COVID-19 vaccine dose or infection.
