The chart shows vaccine protection against Omicron after 1, 2, or 3 shots.
According to official UK statistics, protection against severe illness is high and enhanced by third shots.
Boosters raise it, but protection against getting mild illness is much lower.
The new chart shows how much protection is provided by one, two, and three doses of the vaccine against the Omicron coronavirus variant.
It was Published Friday by the UK Health Security AgencyIt utilizes data collected during the country’s Omicron surge in late December.
The vaccine has been found to provide much less protection against catching COVID-19 at Omicron than Delta, but remains more protective against hospitalization.
Protection against hospitalization diminished over time after the second dose, but was increased again by booster shots.
This study is based on data collected from 27 November 2021 to 24 December 2021. It provides the first formal assessment of the efficacy of booster immune vaccines for severe diseases. Tweeted on Friday.
Here are the statistics.
In case of hospitalization (combined of all vaccine brands):
Single dose: The risk of hospitalization was reduced by 52% compared to unvaccinated.
Two doses: 72% reduction within 24 weeks of the second dose.
Two doses (long term): The risk was reduced by 52% in the 24 weeks of the second dose.
3 doses: The risk was reduced by 88% 2 weeks after the 3rd injection.
For symptomatic diseases (combined of all vaccine brands):
Single dose: Reduces the risk of contracting symptomatic COVID-19 by 26% within 4 weeks of the first dose.
Two doses: 18% reduction within 24 weeks of the second dose.
2 doses (long term): 2% reduction in 24 weeks of the second dose.
3 doses: The risk was reduced by 63% 2 weeks after the 3rd injection.
The data are from the United Kingdom and are not fully applicable to the United States with different sets of vaccines.
Most older people in the UK were given the AstraZeneca vaccine, which is not used by the United States. In the UK, I have never used a Johnson & Johnson single vaccine. Both countries use Pfizer and Moderna vaccines, and the UK uses them exclusively in booster rollouts.
The findings seem to confirm that vaccination and booster immunization are effective tools for Omicron. Subspecies are sweeping the world and risk pushing the healthcare system to the “brink of collapse.” The World Health Organization recently said.
It’s not clear how long booster protection will last. UKHSA Previously reported Protection against symptomatic disease decreased from 70% to 45% 10 weeks after the Pfizer booster in those who had already received two doses of Pfizer.
