British Society for Immunology calls for a robust programme monitoring the body’s immune response
Experts have called for greater clarity on the monitoring in place to assess the 12-week dosing interval for Covid-19 vaccines, as the row over delayed second doses continues.
The UK’s coronavirus vaccination programme was shifted late last year to prioritise administering the first dose of jabs to as many at-risk people as possible. As a result, the interval between the two doses of the jab was increased to up to 12 weeks.
