Vaccine drugmaker Pfizer says its studies show three doses of its COVID-19 vaccine neutralized the omicron discrepancy while two doses reduced asperity .
“ These are studies where they try to look at how much antibody does it take to neutralize the virus in a test tube, ” says Dr. John O’Horo, an infectious diseases specialist at Mayo Clinic. “ What they found in these studies is that you need a significantly higher titer, or concentration of antibodies, to neutralize omicron compared to delta or the former variants. however, what they besides found is that it will placid neutralize at these higher titers. ”
“ The good news program here is that there is n’t a complete immune miss. This is telling us that there will still be some effect from the antibody part and, in all likelihood, from the vaccines. But at the same time, we expect there to be some decrease based on requiring this higher concentration. ”
Watch: Dr. John O’Horo talks about why getting a COVID-19 vaccine is more important than ever.

What this truly means for us as individuals is we ‘re going to wait for the real-world data from immunize individuals, which will start to give us insights into how the early parts of the immune system shimmer in. But besides that getting your vaccine and, if you ‘re eligible, your booster remains identical authoritative. That ‘s the best way to get your viral antibody titers adenine high as possible and give you that good gamble of being able to have some increased consequence against omicron, ” says Dr. O’Horo .
For those who have been given a Moderna or Johnson & Johnson COVID-19 vaccine, Dr. O’Horo says there needs to be more data ; however, he says he would not be surprised to see the same general trends of needing a higher titer of antibody to get the same the level of auspices. He recommends everyone who is eligible to get a boo ster to optimize protection against COVID-19 .
While much of the stream focus is on omicron, Dr. O’Horo says COVID-19 infection rates remain high because of the delta version .
“ Despite all the concern around omicron, it remains critical to focus on delta because that ‘s still what ‘s here, and that ‘s hush what ‘s filling up our hospitals, particularly in the Midwest, ” says Dr. O’Horo. “ We know that the vaccines are fabulously effective against delta. And this is the best reason to get vaccinated or boosted correct nowadays, if you ‘re eligible, because delta is a clean threat in the here and immediately. Omicron is something that has some business. ”
Along with vaccination and getting a booster if eligible, other preventive measures remain important as well, including masking when appropriate, getting tested if you have symptoms or another argue, and physical distance .
Looking ahead, Dr. O’Horo says the drug companies that make vaccines have investigated making specific boosters for variants .
“ And we are going to have to see what kind of developments come out from the real-world data on efficacy in the dear future, american samoa well as what the what this looks like overall, ” he says. “ It will be significant to remember if there is a new booster in the spring for this, that that ‘s something that ‘s always been considered a possibility. however, that does n’t mean you should n’t get a promoter now. The COVID-19 boosters now distillery improve your gamble profile better than anything. And barely getting a booster now does n’t mean that there wo n’t always be another supporter. Just like the influenza, we have to get a shoot every year as new strains come about. ”
