After 30 June 2023, COVID-19 vaccinations will only be available for people who are at higher risk from severe COVID-19, including those with a weakened immune system (described below), and a wider group of people such as those with an underlying health condition. The vaccine will then usually only be offered seasonally (for example, during the autumn-winter period), except for people who have a severely weakened immune system, who may be specifically advised to get the vaccine sooner.
