3 shots of AZ vaccine…worst of the multi-jab big three…75% protection…Moderna and Pfizer likely to be higher…(despite British claims)…
BBC: Early analysis of UK Omicron and Delta cases showed the vaccines were less effective at stopping the new variant.
But a third booster prevents around 75% of people getting any Covid symptoms.
Meanwhile, Levelling Up Secretary Michael Gove, who chaired a meeting with first ministers of the devolved nations this afternoon, warned the UK faces a “deeply concerning situation”.
Speaking after the meeting of the government’s emergency committee Cobra, he said measures taken so far were “proportionate”, but ministers were “absolutely” keeping everything under review.
“Action is absolutely required, and as new data comes in we will consider what action we do require to take in the face of that data,” he added.
One of the main concerns since the heavily-mutated Omicron variant first emerged was that it would make vaccines less effective.
The UK Health Security Agency report analysed data from 581 Omicron cases and thousands of Delta cases to calculate how effective the vaccines were against the new variant.
The analysis is based on limited data, but showed a dramatic drop in effectiveness for the Oxford-AstraZeneca vaccine and a significant drop off for two doses of Pfizer.
The 75% protection against Covid symptoms after a booster is not as high as against previous variants.
