A third booster dose of the Covid-19 vaccine provides 70-75 percent protection against symptomatic infection from the Omicron variant, the UK Health Security Agency (UKHSA) said on Friday.

In its latest technical briefing, the agency said that two doses of both the Oxford/AstraZeneca administered in India as Covishield and Pfizer/BioNTech vaccines provide “much lower levels” of protection against symptomatic infection compared to the currently dominant Delta variant of Covid-19.
