More COVID-19 booster shots may be on the way — but when it’s your turn, you’ll get an extra dose of the original vaccine, not one updated to better match the extra-contagious delta variant.
“I don't quite understand why this is not delta because that's what we're facing right now,” fellow adviser Dr. Patrick Moore of the University of Pittsburgh said last week as government experts debated whether it's time for Moderna boosters. He wondered if such a switch would be particularly useful to block mild infection.
That means there’s no guarantee a delta-specific booster would protect any better, said University of Pennsylvania immunologist John Wherry. Waiting for studies to settle that question — and if necessary, brewing updated doses — would have delayed rolling out boosters to people deemed to need them now.
Both companies first experimented with tweaked doses against a mutant that emerged in South Africa, the beta variant, that has been the most vaccine-resistant to date, more so than the delta variant. Lab tests showed the updated shots produced potent antibodies. But the beta variant didn’t spread widely.
And Penn’s Wherry said it is critical to carefully analyze how the body reacts to updated shots because the immune system tends to “imprint” a stronger memory of the first virus strain it encounters. That raises questions about whether a subtly different booster would prompt a temporary jump in antibodies the body’s made before — or the bigger goal, a broader and more durable response that might even be better positioned for the next mutations to come along.
Nah. I got the J&J shot. F the booster bit. Unless J&J gets their own booster going, I am NOT gonna try to off myself by mixing an experimental mRNA Nanotechnology JAB, with J&J that's an ACTUAL vaccine. That's a dangerous, deadly cocktail! NEVER. MIX. MEDICINE.
Got vaccinated but probably won’t get the booster.
Yahoo ERASMUS University in Netherland,Fort Dix and the Red Chinese Laboratories in WooHAN China!Did they even bother to develop a Cure for the 'Depopulation Plan'FIRST before UNLEASHING IT? EVERYBODY WANTS TO KILL THEIR OWN POPULATIONS!
Got mine almost two weeks ago. ScienceMatters scienceisgod Fringe
Hello!!! Vaccines don’t work
My booster better be LSD.
