Once we have offered vaccination to these groups, we will therefore continue to follow recently published JCVI advice by inviting adults under 50 who have not yet received the vaccine in age cohorts, as follows:All those aged 40-49 yearsAll those aged 30-39 yearsAll those aged 18-29 years The JCVI’s recommendation continues to be that an age-based approach is the best way to address the risk of severe illness and mortality associated with the virus and this approach helps us to do that as quickly as possible.
