‘Very concerning news for the vaccinated: Looks like the Omicron mRNA booster doesn’t work against Omicron
In animal tests, it actually produced FEWER antibodies to both Omicron and the original virus than a third shot of the original Moderna vaccine.
The researchers said it, not me:
“An Omicron boost may not provide greater immunity or protection compared to a boost with the current mRNA-1273 vaccine.”
Which wouldn’t matter if the “current mRNA-1273 vaccine” actually worked against Omicron.
How many Hail Marys to repent for Original Antigenic Sin?
No joke, though, this is seriously worrisome as it implies that if the Omicron experience is any guide, mRNA vaccinated people will be exposed to infection from future variants going forward, unless their own immunity kicks in.
