|C.D.C. research finds that tightly fitted masks, or doubling up with both cloth and surgical masks, could reduce virus transmission by up to 96.5%.|

Wearing a mask — any mask — reduces the risk of infection with the coronavirus, but wearing a more tightly fitted surgical mask, or layering a cloth mask atop a surgical mask, can vastly increase protections to the wearer and others, the Centers for Disease Control and Prevention reported on Wednesday.
New research by the agency shows that transmission of the virus can be reduced by up to 96.5 percent if both an infected individual and an uninfected individual wear tightly fitted surgical masks or a cloth-and-surgical-mask combination.
To summarize some encouraging vaccine news in today’s New York Times:
- All five vaccines with public results have eliminated Covid-19 deaths. They have also drastically reduced hospitalizations. “They’re all good trial results,” reports Caitlin Rivers, an epidemiologist at Johns Hopkins University. “It’s great news.”
- Don’t focus on the relatively minor differences among the vaccine results. The available data is very encouraging — including the vaccines’ effect on the virus’s variants.
- Coronaviruses have been circulating for decades if not centuries, and they’re often mild. The common cold can be a coronavirus. The world isn’t going to eliminate coronaviruses — or this particular one— anytime soon.
- We don’t need to eliminate Covid-19 for life to return to normal. We need to downgrade it from a deadly pandemic to a normal virus.
- All five vaccines — from Pfizer, Moderna, AstraZeneca, Novavax and Johnson & Johnson — look extremely good. Of the roughly 75,000 people who have received one of the five in a research trial, not a single person has died from Covid, and only a few people appear to have been hospitalized. None have remained hospitalized 28 days after receiving a shot.
- For perspective, in 75,000 American adults, Covid has killed roughly 150 and sent several hundred more to the hospital. The vaccines reduce those numbers to zero and nearly zero, based on the research trials. A typical U.S. flu season kills between five and 15 out of every 75,000 adults and hospitalizes more than 100.
- When you read that the Johnson & Johnson vaccine was 66 percent effective or that the Novavax vaccine was 89 percent effective, those numbers are referring to the prevention of all illness. Researchers count mild symptoms as a failure.
- What about the highly contagious new virus variants that have emerged in Britain, Brazil and South Africa? There is no evidence yet that it increases deaths among vaccinated people. Two of the five vaccines — from Johnson & Johnson and Novavax — have reported some results from South Africa, and none of the people there who received a vaccine died of Covid.
- The vaccines still provide considerable protection against the variant, though less than against the original version. Some protection appears to be enough to turn this coronavirus into a fairly normal disease in the vast majority of cases.
- Any of the five vaccines can save your life. If you have to choose between getting the Johnson & Johnson vaccine now or waiting three weeks to get the Moderna or Pfizer vaccine, the experts say: Get what you can, as soon as you can. Don’t risk three more weeks of exposure.
