With topsy-turvy results for doses 1 and 2 and confidence intervals wide enough to drive a bus through, PHE's latest vaccine study leaves a lot to be desired.

A new study of over 50,000 employees of the healthcare system in Cleveland, Ohio, has found that previous infection gives very robust protection against re-infection and there is no gain to being vaccinated as well.

Matt Hancock told MPs that 1% of Indian variant cases (126 of 12,383) were hospitalised. That compares to 2% with the British variant over the winter peak, suggesting the scariant is nothing to fear.

In its third weekly vaccine surveillance report, PHE revises down its estimate of AZ efficacy to a lower bound of 65%. Are Government scientists becoming worried about the fitness of their "workhorse" vaccine?

So do the vaccines not work then? That's the impression you'd get from the way various members of SAGE are carrying on, warning of new waves and new variants and the need to delay the end of lockdown even further.

Infection 64% less likely to put you in hospital and 72% more likely to be asymptomatic – some good news on the vaccines from ZOE. But for the high risk the news is not all so good.
