Study suggests Omicron-specific booster may not provide more protection

A new study conducted in primates suggests there may not be a benefit from updating Covid-19 vaccines to target the Omicron variant at this time.

The work, by scientists at the National Institutes of Allergy and Infectious Diseases’s Vaccine Research Center, shows that animals boosted with the original vaccine had similar levels of protection against disease in the lungs as did primates that received an updated booster based on the Omicron strain. The work was done with Moderna’s licensed vaccine and a booster shot based on the Omicron variant.

Study of blood from the animals showed that many of the measurable immune responses — rises in neutralizing antibody levels, for instance — were not substantially different, regardless of which booster shot they were given.

“Therefore, an Omicron boost may not provide greater immunity or protection compared to a boost with the current [Moderna] vaccine,” the researchers concluded.

The study was posted to a preprint server on Friday. It has not yet gone through peer review.

Senior author Robert Seder said the findings are similar to those of a study the group conducted last year, when researchers compared a booster shot based on the Beta variant to the existing vaccine. In that case as well, data generated in primates suggested boosting with the original vaccine was as effective at protecting the lungs as was a booster based on the Beta variant. (That variant of concern, first spotted in South Africa, did not spread globally.)

“These data would suggest that the initial imprinting of the initial vaccine generated B cells that … when you give them a boost six or nine months later, they’re cross-reactive to Omicron or Beta or Delta,” said Seder, chief of the cellular immunity section at the Vaccine Research Center.

It seems unclear if the animals even developed omicron-specific antibodies or if their immune systems dealt with the "omicron booster" spikes using the antibodies it already created from prior doses of the original vaccine. If that's what's happening, what can be done?

it’s all a waste of money:

2 Feb: UK Express: Scandalous! £8.7billion of YOUR money has been wasted
THE true scale of pandemic waste was revealed yesterday when it emerged the Government has written off an astonishing £8.7billion loss on PPE.
By SAM LISTER
The wasted money is more than the Ministry of Justice budget, about seven percent of NHS running costs, or enough to build more than a dozen new hospitals...

Or he just plain doesn’t care if they infect Americans with it and some of them die.

It might be useless but it’s still mandatory. Please, get with the program.

Omicron is disappearing quickly. The “Omicron-specific” booster isn’t needed.

Anything mRNA related is bad.... Natural immunity is best.

Yet at work, nearly everyone is vaxxed and boosted and nearly everyone got Omicron.
