LONDON, Dec 10 (Reuters) - Booster COVID-19 vaccine shots
give 70% to 75% protection against mild disease from the new
Omicron variant, the UK Health Security Agency said on Friday.
In an analysis of 581 people with confirmed Omicron, two
doses of AstraZeneca and Pfizer-BioNTech
vaccines provided much lower levels of protection
against symptomatic infection compared to what they provide
against Delta.
However, when boosted with a dose Pfizer vaccine, there was
around 70% to 75% protection against sympomatic infection for
people, regardless of which initial vaccine they received.
