six fold reduction in neutralizing titers?
or did I read that wrong?

Dr. Zaks said that the new version of the Moderna vaccine, aimed at the South African variant, could be used if needed as a booster one year after people received the original vaccine.
The need for such a booster may be determined by blood tests to measure antibody levels or by watching the population of vaccinated people to see if they begin falling ill from the new variant
.
"We don't yet have data on the Brazilian variant," Dr. Zaks said. "Our expectation is that if anything it should be close to the South African one. That's the one with the most overlap." New forms of the virus will continue to emerge, he said, "and we'll continue to evaluate them."
Noting that Moderna took 42 days to produce the original vaccine, he said the company could make a new one "hopefully a little faster this time, but not much."One reason the current vaccine remains effective is a "cushion effect," meaning it provokes such a powerful immune response that it will remain highly protective even with some drop in antibody strength, Dr. Anthony S. Fauci, the government's leading expert on infectious diseases, and President Biden's adviser on the coronavirus, said at a news briefing on Friday.
Experts also cautioned against assuming that a decrease in neutralizing ability meant the vaccines were powerless against the new variants. Neutralizing antibodies are just one component of the body's immune defense, noted Akiko Iwasaki, an immunologist at Yale University.
"In real life, there's also T cells and memory B cells and non-neutralizing antibodies and all these other effectors that are going to be induced by the vaccine," Dr. Iwasaki said. Neutralizing power is "very important, but it's not the only thing that's going to protect someone."
i'll caveat this - we have no idea clinically. there hasn't been a trial.Quote:
1. The vaccine so far is effective against the new variants, even at reduced efficacy for the SA variant

maybe I'm too close to the acute cases (fair criticism) but it's enough to make me personally not want to catch it that's for sure
A certain poster here is dealing out the worst case scenario here and on the Aggieland forum as fact. It displays a crazy amount of medical ignorance and a completely irresponsible level of fear mongering. It's sick. It's sad when only the "experts" that fit your world view are in the right. Everyone else is a "denier". It's also really cute to follow up blanket insults with calls for unity. This was a forum that dealt as much as possible in real data and black and white. People like B&R have made this forum no different than the politics forum with all their "what if's" based on information taken from politically charged news outlets.The Big12Ag said:
Some people tend to imagine the worst possible outcome instead of understanding the outcome currently expected or the most likely outcome.
I did say "possible", so there is a chance some horrible mutation occurs to make it more deadly or less preventable with current vaccine.
But what was shared in articles and experts on this thread did NOT say that has happened and therefore it is NOT fact. But, it is possible. Not expected, or most likely, but possible. If that's were you want your thoughts to dwell - in worst case but unlikely scenarios - that is your choice.

That's not really how evolution works. Selection can only act on existing genetic variability, and thus environmental stress doesn't make it any more likely that a beneficial variant relative to that stressor exists or will arise in a given population. It only makes it more likely that such a variant would be selected for if it already was present.cone said:

Technically, dinosaurs were already birds based on our definition of the term and birds today are the last living dinosaurs.amercer said:FratboyLegend said:That's not the way evolution works.cone said:

What a ridiculous thing to say.
I mean, that is how we got birds, but it's leaving a lot of nuance on the table....

Thanks for saying with sophistication what I was trying to convey as a layperson.Infection_Ag11 said:That's not really how evolution works.

You're too close to the very rare acute cases.
