The British health agency (UKHSA) unveils this Friday a study evaluating at 88% the effectiveness of three doses of vaccine against the risk of hospitalization linked to the Omicron variant, compared to an unvaccinated person
According to a study published this Friday by the British health agency (UKHSA), the booster dose of the vaccine against Covid-19 (all brands combined) allows people affected by the Omicron variant to avoid hospitalization in 88% of cases compared to unvaccinated, with a confidence interval estimated by researchers between 78% and 93%.
The study evaluates the efficacy at 72% with a second dose received for 2 to 24 weeks, and at 52% with a second dose later (just under 6 months) or a single dose of vaccine. “More data will be needed to assess the duration of this protection against hospitalization,” warns the agency.
More effective than against Delta
According to this same study spotted by “Le Parisien”, if we consider only symptomatic patients who have received three doses of the vaccine, the probability of requiring hospitalization is 68% for people who have contracted the Omicron variant against 89% with Delta. .
Prime Minister Boris Johnson indicated on Wednesday that up to 90% of Covid-19 patients admitted to intensive care have not received a vaccine booster dose, also renewing his call for a third dose.
