A booster vaccine is 88% effective at preventing people ending up in hospital with Covid-19, new data from the UK Health Security Agency suggests.

The new data confirms that two doses of the AstraZeneca, Pfizer or Moderna vaccines offers little protection against being infected with Omicron.

But protection against severe disease appears to be holding up much better against the new variant.

Health officials said this reinforces the importance of getting a third dose.

1. Hospitalization risk reduction: one shot: 52%, 2 shots: 72% (fades to 52%..), 3 shots: 88%

The UKHSA analysed more than 600,000 confirmed and suspected cases of the Omicron variant up to 29 December in England.

It found that a single vaccine dose reduced the risk of needing hospital treatment by 52%. Adding the second dose increased the protection to 72%, although after 25 weeks ((~half a year)) that protection had faded to 52%.

And two weeks after getting a third dose, that protection against hospitalisation was boosted to 88%.
