The 12th of our regular round-ups of Covid vaccine safety reports and news from a group of medical doctors to inform the debate on vaccination.
By comparing Delta when new to Alpha when spent, it's like comparing an athlete to a pensioner. The comparison tells us nothing useful.
Reported infections in England are rising in the most vaccinated age groups while they fall in the under 40s, and hospital admissions are getting older again. Is this a sign of declining vaccine effectiveness?

A new study based on the ONS Infection Survey finds that, contrary to other recent figures, the vaccines protect well against Delta infection. However, a closer look reveals some serious problems.
