Pfizer COVID-19 booster shot extends strong protection, vaccine being updated to target Delta

Source: USA Today

A booster shot of the COVID-19 vaccine made by Pfizer and BioNTech strongly extends protection, a new study from the companies shows, and they are developing a vaccine targeted directly at the Delta variant, which first arose in India.

The companies say they have demonstrated that a third dose of their vaccine, given six months after the second, increases neutralizing antibodies five to tenfold against the original virus and the so-called Beta variant, which was first identified in South Africa. The booster was also found to be safe.

The companies are also updating their vaccine, called BNT162b2, to directly address the Delta variant. They are currently producing material for a clinical trial, which they expect to begin in August, pending regulatory approvals.

Olivier Schwartz, head of the Virus and Immunity Unit, at Institut Pasteur in Paris, published a scientific article Thursday, showing that two doses of the Pfizer-BioNTech vaccine protects against the Delta variant, though a single dose does not.

The irony is that anti-vaxxers get a self-fulfilling wish by depressing vaccinations, infections continue to spread, which allows for the continued development and spread of variants.

1. As I Predicted

Delta variant just too damn dangerous.

If it weren't for the Maganderthals, we could have vaccinated enough of the country to head this variant off at the pass.

But nooooooooooo!

2. I'm taking the news of its reduced effectieness with a pound of salt

It's not that I mistrust Israel, I don't, not at all, not when it comes to medical matters. It was just one study and limited in scope.

More countries need to follow this before we know for certain.

4. yes I saw that. The Israeli study suggested the Pfizer vaccine was declining in protecting

against the Delta and other variants as time went on.

I think we will probably need boosters every few years as the virus mutates beyond the present vaccines, RNA viruses mutate very quickly. Having a ready pool of Republican ignoramuses who willingly grow the virus will allow it to mutate within years instead of decades.

5. FEMA quarantine camps are looking better and better by the day.

You either get vaccinated if there not good medical reason not to OR you go to the camps.

You get out of the camps by being vaccinated.

6. Wish this were possible, but it's not.

In the US, we put children and refugee families in camps, but not willfully infectious persons.
