Sajid Javid has announced people over 75, the immunosuppressed and those living in care homes will be offered a Covid-19 booster this spring.
The Health Secretary confirmed the top-up jab would help those at the highest risk of serious coronavirus maintain a high level of protection against the virus.
Full details of the rollout will be set out shortly, but the NHS in England will make the extra dose available to at-risk groups from around six months after their last jab.
