- According to a new CDC study, a COVID-19 booster vaccination dose is very protective against becoming seriously sick with the Omicron form.
- People who had gotten a COVID-19 booster dosage were far less likely to end up in the ER or hospitalized.
- Another research discovered that persons who have had a booster shot, particularly older folks, are more protected against illness and mortality than those who have not been vaccinated.
The Centers for Disease Control and Prevention (CDC) has released new study indicating that a third COVID-19 vaccination dosage, or booster, gives excellent protection against becoming critically sick with the coronavirus’s Omicron form.
“These reports add to the importance of staying up to date with COVID vaccinations — that means getting your primary series and getting boosted when eligible — to protect against severe COVID-19,” Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, said at a White House briefing on Friday. Researchers reviewed data from 10 states from August 2021 to January 2022 in one study released by the CDC.
The scientists discovered that those who got a third COVID-19 vaccination dosage were 82 percent less likely to show up in an emergency department or urgent care clinic during the Omicron wave than the unvaccinated. They were also 90% less likely to be hospitalized than unvaccinated people. When compared to the Delta wave, both forms of protection were reduced during the Omicron wave.
Additional studies show booster protection
The CDC’s Trusted Source examined COVID-19 cases and fatalities reported in 25 state and local health agencies between April and December 2021. During the Delta wave, persons who had gotten a booster dosage had better protection against illness and mortality than those who had been completely vaccinated but not boosted, according to the study. During the Omicron wave, those who had been boosted were also more resistant to sickness. Researchers did not have data on mortality during the Omicron wave due to a delay in reporting COVID-19 deaths.
People over the age of 65 received the most protection, followed by those aged 50 to 64. “[The research] clearly reveals that unvaccinated people had considerably greater rates of illness and mortality,” said Dr. Shobha Swaminathan. In fact, she said that unvaccinated participants in the research had a nearly 20-fold greater chance of dying from COVID-19 than fully vaccinated ones.
Researchers examined data from more than 70,000 persons who were tested for coronavirus infection using a pharmacy-based testing program in a third study, which was published in the Journal of the American Medical Association.
The scientists discovered that three doses of the vaccine gave higher protection against symptomatic illness than two doses or being unvaccinated. In comparison to the Delta form, full immunization and boosters gave reduced protection against the Omicron variation. According to laboratory tests, Omicron may partly override the protection provided by vaccinations and pre-existing immunization.
The CDC also released more COVID-19 data on its website last week, indicating that unvaccinated Americans aged 50 to 64 were 44 times more likely to be hospitalized in December than those who were completely vaccinated and got a third dose. Unvaccinated adults 65 and older had a 49-fold increased risk of hospitalization.
The CDC advises Americans to keep their vaccines “up to date.”
According to these research, comprehensive immunization and boosters provide a robust resistance against illness and hospitalization, even during the Omicron wave.
“These findings back up what we’re witnessing in our hospital and other institutions around the nation,” Swaminathan said. “The majority of COVID-19 fatalities and ICU admissions occur among the unvaccinated, and [this study] should hopefully inspire more individuals to be vaccinated and boosted.”
Despite this, about 210 million individuals in the United States, or around 63 percent of the entire population, have gotten two doses of a COVID-19 vaccination. And slightly under 84 million individuals, or around 40% of those completely vaccinated, have received a booster dose. The CDC now advises booster doses at least 5 months after the initial series of the Pfizer-BioNTech or Moderna-NIAID vaccinations, or at least 2 months after a single dose of the Johnson & Johnson vaccine for everyone 12 years and older.
As the value of boosters becomes evident, the CDC has altered its emphasis from pushing Americans to be “completely vaccinated” to asking them to be “up to date” on their doses. “If you’re qualified for a booster and haven’t received it, you’re not up to date,” Walensky said during the press conference.
