FDA says J&J 1-dose shot prevents COVID; final decision soon

WASHINGTON (AP) — Johnson & Johnson’s single-dose vaccine protects against COVID-19, according to an analysis by U.S. regulators Wednesday that sets the stage for a final decision on a new and easier-to-use shot to help tame the pandemic.

The Food and Drug Administration’s scientists confirmed that overall the vaccine is about 66% effective at preventing moderate to severe COVID-19. The agency also said J&J’s shot — one that could help speed vaccinations by requiring just one dose instead of two — is safe to use.

That’s just one step in the FDA’s evaluation of a third vaccine option for the U.S. On Friday, the agency’s independent advisers will debate if the evidence is strong enough to recommend the long-anticipated shot. Armed with that advice, FDA is expected to make a final decision within days. ...

Not to be sniffed at: Agony of post-COVID-19 loss of smell

Tue, 2021-02-23 12:01 — mike kraft

Researchers still investigating loss of smell problems among some of Covid victims

... A year into the coronavirus pandemic, doctors and researchers are still striving to better understand and treat the accompanying epidemic of COVID-19-related anosmia — loss of smell — draining much of the joy of life from an increasing number of sensorially frustrated longer-term sufferers like Forgione.

Even specialist doctors say there is much about the condition they still don’t know and they are learning as they go along in their diagnoses and treatments. Impairment and alteration of smell have become so common with COVID-19 that some researchers suggest that simple odor tests could be used to track coronavirus infections in countries with few laboratories.

British data study says COVID-19 vaccines sharply cut hospitalizations

Mon, 2021-02-22 18:11 — mike kraft

LONDON (AP) — Two U.K. studies released Monday showed that COVID-19 vaccination programs are contributing to a sharp drop in hospitalizations, boosting hopes that the shots will work as well in the real world as they have in carefully controlled studies.

Preliminary results from a study in Scotland found that the Pfizer-BioNTech vaccine reduced hospital admissions by up to 85% four weeks after the first dose, while the Oxford-AstraZeneca shot cut admissions by up to 94%. In England, preliminary data from a study of health care workers showed that the Pfizer vaccine reduced the risk of catching COVID-19 by 70% after one dose, a figure that rose to 85% after the second.

“This new evidence shows that the jab protects you, and protects those around you,” U.K. Health Secretary Matt Hancock said. “It is important that we see as much evidence as possible on the vaccine’s impact on protection and on transmission and we will continue to publish evidence as we gather it.’’
