January 24, 2022 – Enhanced footage of Pfizer and Modern COVID-19 vaccines It appears to be very effective in preventing hospitalizations due to the Omicron variant, according to three new CDC studies released Friday.
Additional doses were 90% effective in keeping people out of the hospital after infection and 82% effective in preventing emergency service visits and emergency care.
“These reports add more evidence of the importance of keeping up with COVID vaccinations“, Said on Friday Rochelle Walensky, MD, director of the CDC during a news briefing by the White House COVID-19 Response Team.
Data from Israel and other countries suggest that supplemental injections may prevent serious illness and hospitalization, but it has not been clear so far whether additional doses will have the same effect in the United States. In three CDC studies, researchers reviewed millions of cases and tens of thousands of hospitalizations and deaths during the Delta and Omicron waves.
IN one study, researchers analyzed hospitalizations and visits to emergency departments and emergency clinics in 10 states between late August 2021 and early January 2022. The effectiveness of the Omicron hospitalization vaccine dropped to 57% for those who received a second dose more than 6 months earlier. Booster shot restored protection to 90%.
IN another study, researchers analyzed nearly 10 million cases of COVID-19 and more than 117,000 deaths reported in 25 state and local health departments between April and December 2021. Cases and deaths were lower among people who received an overdose compared to those who were fully vaccinated but not amplified. Cases and deaths were even lower among reinforced Americans than among those who were not vaccinated.
IN third study, which was published in PIT, the Journal of the American Medical Association, researchers looked at data from more than 70,000 people tested for COVID-19. The third dose provides greater protection against infections with symptoms than two doses or without a dose. Complete vaccinations and reinforcements protected less from the Omicron variant than from the variant Delta variant.
CDC too published data on Thursday which showed that unvaccinated adults aged 65 and over who were infected with COVID-19 were 49 times more likely to be hospitalized than those who were vaccinated and received supplementary vaccines. At age 50 and older, unvaccinated adults are 45 times more likely to be hospitalized than those who have been vaccinated and vaccinated.
“There are still millions of people who qualify for the overdose and have not yet received it,” Walensky said on Friday. “As we continue to face the Omicron variant, which accounts for more than 99% of infections in the United States today, I urge anyone who qualifies to receive the supplementary vaccine to receive it as soon as possible.”
