Paris: Vaccination is highly effective in preventing serious cases of Covid 19, even against the Delta, according to an extensive study in France.
Research published Monday – Focusing on Preventing Severe Cavity and Mortality, Not Infection – looked at more than 50 million to 22 million people and found that those who got jobs were more likely to be hospitalized or die. Chances are 90% lower.
The results confirm observations from the United States, Britain and Israel, but researchers say it is the largest study of its kind to date.
Based on data collected in December 2020, when France launched its campaign, researchers compared the results of 11 million vaccinated people with 11 million unprotected subjects.
They paired up with a non-vaccinated individual who met the vaccinated counterpart in the same area and the same age and sex, tracking them from the second date of vaccination to July 20. ۔
After 14 days of the second dose, the risk of a vaccinated subjects-severe coed reduced by 90%, according to research by Epiphare, an independent drug safety research group that works with the French government closes.
Vaccination is almost as effective as for the Delta, 84 percent for people 75 and older, and 92 percent for people 50-75.
However, this estimate is based on one-month figures only, as it only took effect in June in France.
“This study should be followed to include the results of August and September,” Epidemiologist Epidemiologist Mahmoud Zorik told AFP.
The study covered vaccinations with Pfizer / Biotech, Moderina and AstraZeneca Jobs, but not Jensen, which was later adopted and rarely used in France.
The results also show that vaccine protection against severe COVID-19 did not decrease during the study – up to five months.
