Analysis by the UK Health Security Agency (UKHSA) revealed immunity gained from third Covid jabs fades quicker against Omicron than Delta.
Its surveillance report shows adults who received two AstraZeneca doses, plus a Pfizer or Moderna booster, are 60 per cent less likely to get symptoms than the unvaccinated if they catch Omicron up to four weeks after their third jab.
But after ten weeks, efficacy drops to 35 per cent for Pfizer and 45 per cent for Moderna.
Meanwhile, those who received Pfizer for all three of their doses saw their protection levels increase to around 70 per cent for two weeks after their top-up dose before falling to around 45 per cent 10 weeks later.
People given two Pfizer vaccines and a Moderna booster were the most protected, according to the report, with efficacy sitting at 75 per cent against Omicron and lasting for at least nine weeks.
