3rd vaccination prevents 95% deaths from COVID for over 50 year-old = Korea

Analysis shows that if people in their 50s and older are vaccinated with the COVID-19 three times, the risk of hospitalization and death from the Omicron strain can be reduced by 90% or more.

According to the Reuters on 27th (local time), the UK Health and Safety Agency (UKHSA) announced that the it is risen to 95% for effect in preventing death from infection with the Omicron strain in people in their 50s and older who have been vaccinated with the COVID-19 three times.

Six months after two vaccinations by people in their 50s and older, the effect of preventing death from infection with the Omicron strain drops to about 60%, but with the third vaccination, it takes two weeks. UKHSA explained that it will increase to 95%.

UKHSA explained that the third vaccination also reduced hospitalization rates for infection with the Omicron strain. According to UKHSA analysis, the third dose of Pfizer was 90% effective in preventing hospitalization. However, 10 to 14 weeks after the third inoculation, the effect drops to 75%. In the case of the modelna, the effect was maintained at the level of 90% to 95% even 9 weeks after the third inoculation.

It was also confirmed that the third vaccination had the same effect on stealth omicron, which is a variant of omicron that is spreading in the United Kingdom and Denmark.

Twenty-five weeks after the second vaccination, UKHSA is less effective in preventing symptoms from infection with the Omicron and stealth Omicron strains, respectively, at 9% and 13%, respectively. However, they announced that they would be vaccinated up to the third time and would increase to 63% and 70%, respectively, two weeks later.

"There is clear evidence that vaccination is effective. The vaccine protects against COVID-19. Vaccination saves us from COVID-19. It is improving the effect of preventing hospitalization and death of vulnerable elderly people," said Mary Ramsey, head of vaccination at UKHSA.
