Who can get a Covid booster jab in England?

The coronavirus booster vaccine dose is designed to improve the protection people have received from getting the first two doses of the vaccine, and combat any waning efficiency. Data from Public Health England (PHE) suggests that the protection provided by vaccines against severe illness gradually decreases over time. The introduction of the third jab started on 20 September. On 15 October, the NHS said more than 3 million people had received it in the first four weeks.
