Booster dose prevents 88% hospitalization with Covid-19 Omicron, new data from UK Health Safety Agency suggests

The new data confirms that two doses of AstraZeneca, Pfizer or Moderna vaccines offer little protection against Omicron infection, but protection against severe diseases seems to be much better against the new variant.

The UKHSA has analyzed over 600,000 confirmed and suspected cases of Omicron by December 29 in England.

He found that a single dose of the vaccine reduced the risk of needing hospital treatment by 52%. The addition of the second dose increased the protection to 72%, although after 25 weeks this protection decreased to 52%.

And two weeks after receiving a third dose, that protection against hospitalization increased to 88%.

The UKHSA report said there is not yet enough data to determine how long this protection will last, but it is expected to last longer than protection against the development of symptoms.

In people who already had symptoms, protection after each dose was slightly lower and decreased to 68% after a Booster compared to unvaccinated people.

A second study, conducted with the University of Cambridge, confirmed that the risk of being hospitalized or hospitalized after being infected with Omicron was about half that of the older Delta.

The study also found that the risk of hospitalization with Omicron alone was about one-third that of Delta.

Susan Hopkins, chief medical officer at the UKHSA, said the data was “in line with the encouraging signs we have already seen”.

However, she said it was too early to draw conclusions about how serious the hospital could be with Omicron compared to Delta.

She added: “The increased transmissibility of Omicron and the increasing number of cases in the UK population over the age of 60 means that there is still a significant likelihood that there will be significant pressure on the NHS in the coming weeks. The data shows once again that the presentation for the vaccine, especially the third dose, is the best way to protect yourself and others from infections and severe illness. ”

In the UK, 90% of the population over the age of 12 are vaccinated with one dose, 82.4% with two doses and 59% with three doses.

The daily number of infections reached a record 189,846, while the average daily death toll from Covid in the last week is 110. At the peak of the January pandemic, the record was 69,000 infections and 1,800 deaths.
