Project #67:
Assessing effectiveness of 3rd / booster COVID-19 vaccine doses in England

  • Topic areas: COVID vaccine effectiveness/safety

The national COVID-19 vaccination effort in the United Kingdom continued in September 2021 with third doses administered to the most vulnerable, and with eligibility extended to the entire adult population by the end of the year.

This study will assess effectiveness of a third dose of COVID-19 vaccine compared with a complete 2-dose vaccination course.
