Millions of eligible people in England can now book their vaccine via the NHS website, the NHS app, or by calling 119 for free if they do not have access online.
From this week, people aged 65 and over, pregnant women, and those with underlying health conditions are set to receive invitations from the NHS to get their COVID-19 and flu vaccines.
The programme was previously set to begin in October, but was brought forward following the emergence of a new COVID-19 variant, BA.2.86, and advice from the Department of Health and Social Care (DHSC) and the UK Health Security Agency (UKHSA).
