One study, published on Wednesday in The New England Journal of Medicine bit.ly/3kgzEZU, identified "high-level, broad-spectrum" antibodies in blood samples from survivors of the original SARS outbreak in 2003 who recently received the Pfizer/BioNTech vaccine against SARS-CoV-2, the virus that causes COVID-19.

ANALYSIS: Why the coronavirus has changed as it has, and what it means going forward

Sat, 2021-08-21 22:05 — mike kraft

Why the coronavirus changed over time, and what it means going forward We can’t predict the next coronavirus variant. But there are some fundamental principles that explain why the virus has morphed as it has. Andrew Joseph STAT

It’s impossible to say how the coronavirus will continue to evolve. Those changes, after all, are a result of random mutations.

Some experts said the new research released by CDC today did not support recommending booster shots for all Americans.

Wed, 2021-08-18 12:51 — mike kraft

The Centers for Disease Control and Prevention released three studies on Wednesday that federal officials said provided evidence that booster shots of the Pfizer-BioNTech and Moderna coronavirus vaccines would be needed by all Americans in the coming months.

But some experts said the new research did not support the decision to recommend booster shots for all Americans.

Taken together, the studies show that although the vaccines remain highly effective against hospitalizations, the bulwark they provide against infection with the virus has weakened in the past few months.
