Three large new studies from the US Centers for Disease Control and Prevention highlight the importance of getting a booster shot to provide the best protection against the Omicron coronavirus variant.

This is the first real-life data to examine the effect of boosters against Omicron, which now accounts for more than 99% of coronavirus cases in the United States. The studies, released Friday, raise the question of whether people with just two vaccine doses should still be considered fully vaccinated."I think we have to redefine fully vaccinated as three doses," said Dr. William Schaffner, a longtime CDC vaccine adviser who was not involved with the studies. Omicron cases dip in the US overall, but the wave is far from over in many parts of the countryThe studies have an enormous scope, involving millions of cases, hundreds of thousands of visits to emergency departments and urgent care centers, and tens of thousands of hospitalizations among adults. Getting boosted was 90% effective at preventing hospitalizations during a period in December and January when Omicron was the dominant variant, according to a CDC study that looked at nearly 88,000 hospitalizations across 10 states.

Former CDC director: What's next with Omicron and the pandemic?In comparison, getting two shots was only 38% effective at preventing those visits when it had been at least six months past the second shot. "I think it's the third dose that really gives you the solid, the very best protection," Schaffner said. That study was published Friday in the CDC's Morbidity and Mortality Weekly Report. A second study, also published in Friday's MMWR, concluded that people with three shots were less likely to get infected with Omicron. Looking at data from 25 state and local health departments, the CDC researchers found that among those who were boosted, there were 149 cases per 100,000 people on average each week. For those who had only two doses, it was 255 cases per 100,000 people. A third study, to be published in the medical journal JAMA, showed that having a booster helped prevent people from becoming ill with Omicron. That study of just over 13,000 US Omicron cases found that the odds of developing a symptomatic infection were 66% lower for people who were boosted compared to those who had only received two shots.

“Fool me once, shame on you. Fool me twice, shame on me.” Just in time for it to not be effective against the newest varient....maybe it is time we stop injecting people. After all...this is a science experiment gone very wrong Getting a booster shot is the best way to prevent Omicron and is a highly likely solution, but some people don't want to get hit because the side effects of the booster shot are not clear.

There is not enough scientific data for vaccinations results for CORONAVIRUS nor variants while mass scientific data is missing from all sectors, false positive tests, erroneous medical testing with the wrong equipment, lack of vital vaccinated contagion tracking. AP CNN WSJ Really? You aswel - its a Cold.

Right! It works so well! Oh I almost forgot…you can jab that booster in your ass too. Right next to the original jabs. 😂😂😂🙏🙏🙏 It is time that BIG PHARMA PAY THE BILL and are held ACCOUNTABLE for their LIES about vaccines. ITS ALWAYS BEEN ABOUT PROFIT$ for BIG PHARMA. NOT HUMAN HEALTH! COVID Policy Is All Wrong! Says Top Immunologist

We need to take this booster, and regular 3 monthly boosters forever. We know this works and the sooner the denialists get with the program, the sooner we can leave our houses!!

U.S. jobless claims jump 55,000 to three-month high of 286,000 as omicron bitesApplications for U.S. unemployment benefits surged by 55,000 last week to 286,000 and hit a three-month high in a sign the omicron outbreak spurred some...

Hahaha, yeah sure. I'll get right on that......cnn is a joke Covaxinapproval Ok, I already had Omicron, just 2 weeks ago. Can I wave my booster shot now? Pleeeeease! Such BS Omicron ísť praid. I call BS. FULLY vax and currently have omicron. 3 days in bed, sore throat, muscles aches. Stop Because it worked so well in Israel?

U.S. weekly jobless claims rise to three-month highThe number of Americans filing new claims for unemployment benefits jumped to a three-month high, likely as a winter wave of COVID-19 infections disrupted business activity, which could constrain job growth this month. Context, the MEDIA won’t give. With OMICRON devastating the Nation, shortages everywhere due to the variant… this isn’t ROCKET 🚀 SCIENCE. IGNORE THE NEGATIVE MEDIA Biden

2 is enough Does the study address all the celebrities dropping dead in their 60s? All vaccinated that is. Only evil people believe cnn That's what u said the last time cnnfakenews Well they don't want them to go to waste do they The CDC has lost all trust. What they say means nothing anymore Boosters don't help against omicron. I know many people who have been boosted and their symptoms were no less than not being boosted.

I’d rather die than live in a Medical Surveillance State for the rest of my life.

Your title is missing that natural immunity has stronger long term support (against all variants) vs boosters ( you need with every new variant) Everyone I know who got boosters, or was recently vaccinated at all, STILL got Omicron. This shit is transmissible AF. You mean this study? The same CDC that thinks you're no longer a transmission point without testing to find out? 🙄

If COVID-19 is anywhere, it is potentially everywhere. COVID-19 vaccines will save many lives. Mask wearing is a good idea. My daughter got the booster 9 days ago, she tested positive today. Lies lies lies Repeat After Me, Laboratory Leak

All three studies found that unvaccinated people faced the highest risks of becoming sick with Covid-19. The CDC currently says a person is considered fully vaccinated after they've received their primary Covid-19 vaccines -- two weeks after receiving their second dose of an mRNA vaccine, or two weeks after their first dose of the Johnson & Johnson vaccine. Booster doses are recommended for everyone age 12 and older five months after their primary vaccination series.Less than half of those eligible to receive booster shots have gotten one, and only about a quarter of the total US population is fully vaccinated and boosted, according to CDC data.Nearly 20% of the US population eligible to be vaccinated -- those age 5 and older -- has not received any dose of Covid-19 vaccine.
