According to reports reaching Oyogist.com, Covid-19 Booster shots could significantly restore protection against milder illness caused by the omicron variant, as part of a reversal of a drastic reduction in vaccine effectiveness, the UK Health Security Agency said on Friday.
Early results from real-world analysis are some of the earliest data on protection against omicron outside of lab studies, which reduce the neutralization action against omicron.
“These predictions should be considered carefully, but a few months after the second job, they suggest that the risk of catching the omicron variant is higher than that of the delta strain,” said Dr Mary Ramsey, head of immunization at UKHSA. Protection from serious illness is expected to be high.
“The data indicate that following the booster vaccine significantly reduced this risk, so I urge everyone to take their booster when they are eligible.”
In a study of 581 people with a validated Omicron, two doses of the AstraZeneca or Pfizer-BioNTech vaccines provided a much lower level of protection against symptomatic infection than those offered against Delta.
However, when the Pfizer vaccine dose is increased, people who initially receive estrogen have approximately 70% protection against symptomatic infection and those who receive Pfizer have 75% protection.
This compares with approximately 90% of the estimated protection against infection from the delta after the booster.
The UKHSA reiterated that Omicron had a growth advantage over Delta and increased the risk of reinfection by 3 to 8 times.
Two UK studies have not yet been publicly demonstrated and three international studies suggest that Omicron has provided a 20 to 40 times reduction in neutralizing antibodies compared to the viruses used to develop vaccines.
Although no Omicron cases have yet led to hospitalization or death, the UKHSA says there is insufficient data to assess the severity of Omicron.
At the current growth rate, the UKHSA estimates that Omicron will account for more than 50% of all COVID-19 infections by mid-December, with more than a million infections in Britain by the end of this month as new measures come into effect to slow down in England. Omicron diffusion.
“The growing number of Omicron variant cases today along with new data is still a booster for those who do not have their booster or, in fact, any vaccine,” said Stephen Powice, medical director of the National Health Service.
