All vaccines wear off lol. This aint news bruh. Pfizer and Moderna vaccines have both been updated to cover Omicron variants. Just like the flu vaccine is updated when new variants emerge. An annual flu vaccine doesn’t necessarily change, but I guess it’s like all other vaccines, it requires updating if you want it to be effective. Some last years, others far less. But Dr. Rod knows better…
From

While Pfizer’s primary vaccine was designed to protect against the original SARS CoV-2 virus, the new bivalent vaccine is formulated to protect against both the original strain and Omicron subvariants BA.4 and BA.5. Studies have shown these vaccines to be effective against both infection and (to a greater degree) severe disease, hospitalization, and death. Some key studies include:
- A New England Journal of Medicine (NEJM) study published in January 2023 focused on people 12 and older in North Carolina’s state vaccine registry data. It found bivalent vaccines from Pfizer and Moderna to be 58.7% effective against hospitalization compared to 25% for the monovalent ones that preceded them, and 61.8% effective against infection compared to 24.9% for the monovalent vaccine. Scientists noted that this study covered a period when Omicron subvariants BQ.1 and BQ.1.1. were circulating, which suggests the updated vaccine was effective against those strains in addition to the ones it was designed to target.
name a vaccine that wears off this quickly, long lasting protection should be the short lasting flop
i was responding to the dumb dinkum dog who claimed that boosters were made because covid had evolved and he compared it to the flu shot
so your post should have been directed at him, as you say there has been 1 devlopment of the vaccine, not 4 or 5, the booster wears off because it is a flop
this was dinkums second crack as well, he called me crazy for suggesting it would be 4 shots a year, that was back before the roll out and i had made that prediction simply based on the idea of planned obsolescence
then when it is 4 shots a year he is back in here making excuses again, its par for the course with delete dog, always comes back for a second crack
