Pfizer’s Covid Vaccine Protection Against Omicron Fades Just Weeks After Second And Third Doses, Study Finds
Forbes ^ | 05/16/2022 | Robert Hart

Immunity against the omicron coronavirus variant fades rapidly after a second and third dose of Pfizer and BioNTech’s Covid-19 vaccine, according to peer reviewed research published in JAMA Network Open on Friday, a finding that could support rolling out additional booster shots to vulnerable people as the variant drives an uptick in new cases across the country.

KEY FACTS

* Levels of omicron-specific “neutralizing” antibodies—which can target the virus and stop it from replicating—decline rapidly after a second and third dose of Pfizer’s shot, according to the Danish study of 128 people who had received two or three doses.

* Antibody levels, which are associated with protection against infection and disease, fell within weeks of getting the shots and were much lower than the level of antibodies specific to the original and delta coronavirus variants, the researchers said.

* Compared to original and delta variants, the proportion of omicron-specific antibodies detected in participants’ blood dropped “rapidly” from 76% four weeks after the second shot to 53% at weeks eight to 10 and 19% at weeks 12 to 14, the researchers found.

* Omicron-specific antibody levels increased after the third dose—nearly 21-fold at week three and nearly 8-fold at week four, compared to four weeks after the second dose—and the shot generated a detectable response in most people for at least eight weeks, the researchers said.

* However, antibody levels started to drop as early as three weeks after the booster shot, falling 4.9-fold for the original variant, 5.6-fold for delta and 5.4-fold for omicron between weeks three and eight.

* The “transient” antibody response after doses two and three mean additional booster shots might be needed to combat the variant, particularly among older people, the researchers said.

It is not a vaccine. And my dog is not a microbiologist. But he is a black Lab.

The booster has a positive antibody reset knee for a very short time…so take the mRNA every 4 weeks?

How does don’t take it at all sound? These people are nuts.

You take yours and I’ll take my remedy. Then don’t come see how I’m doing. You may live or do better than me. It’s your choice. DFWM

Kind of sounds like if you plan on doing something “Covid-crazy” that taking a booster shot a couple weeks in advance might not be a bad idea. Otherwise, it sounds like you may wait.

I wonder if the recent CDC announcement on waiting for just before the fall likely Covid wave might be connected to this kind of analysis.

Omicron is an especially weak virus. Kinda like the sniffles. Even if the vaccine worked, there’s no point.

Plenty of research shows the boosters further weaken the overall immune system, so likely not such a good idea.

If you get the boosters your damaging your immune system. Each shot takes years off of your life. Don’t take the shots.

Hmm. The shots suck so get some more and risk cancer, blood clots, and heart attacks...

Monsters.

It’s all ass backwards. They can’t understand that the more poison you inject, the more worthless your immune system becomes. Wait until the flu season begins for proof.

naturally, JAMA concludes we’re gonna have to be jabbed with LOTS more “boosters” rather than “the vaccines don’t work” ...
