Pfizer’s CEO says Covid vaccine effectiveness drops to 84% after six months - forum456 - 29-07-2021

The effectiveness of Pfizer’s Covid-19 vaccine steadily declines over time, dropping to about 84% for vaccinated people about four to six months after getting their second dose, according to CEO Albert Bourla.

The comments, made on Wednesday on CNBC’s “The Exchange,” are based on the findings of a new company-funded study that has yet to be peer reviewed. It comes as the drugmaker clashes with U.S. health officials over the need for a third Covid vaccine dose to boost immunity protection.



The study found the vaccine’s effectiveness was strongest, at 96.2%, between one week and two months after receiving the second dose. It declined an average of 6% every two months, according to the study, which signed up more than 44,000 people across the U.S. and other countries. The efficacy after “four to six months was approximately 84%,” Bourla said.

We have seen also data from Israel that there is a waning of immunity and that starts impacting what used to be what was 100% against hospitalization. Now, after the six month period, is becoming low 90s and mid-to-high 80s,” Bourla said.

“The good news is that we are very, very confident that a third dose, a booster, will take up the immune response to levels that will be enough to protect against the delta variant,” the executive added, referring to the highly contagious virus strain that’s dominant in the U.S. and other countries around the globe. It’s not uncommon for vaccines to decline in effectiveness over time, Bourla stressed, adding there’s precedent for three-dose vaccines for other diseases.

Maybe he is still talking about the old variants.

In other words the present Pfizer vaccine is not effective against Delta variant? 

The need to come up with new Pfizer vaccine specifically against Delta variant? 

How about new variants in future? 

More jabs?

it takes a year to pass 3 phase testing to come up with a new vaccine, and by the time the vaccine is ready, many new variants pop up, how to catch up?

BS lah, still so good after 6 months?

RE: Pfizer’s CEO says Covid vaccine effectiveness drops to 84% after six months - lvlrsSTI - 29-07-2021

we are all behind the curve, while Covid virus has mutated hundreds of times, we are still using vaccines developed 8 months ago that are meant for fighting original virus from Wuhan. We need quickly come up with new vaccines that can protect us from all the major variants, time is running out, the 5th started in the US, daily cases jumped to 30k plus overnight.
