COVID vaccine found highly effective in real-world study; eligibility opening up across US
The U.S. government’s first look at the real-world use of COVID-19 vaccines found their effectiveness was nearly as robust as it was in controlled studies.
The two vaccines available since December — Pfizer and Moderna — were highly effective at 90% after two doses, the Centers for Disease Control and Prevention reported Monday. In testing, the vaccines were about 95% effective in preventing COVID-19.
“This is very reassuring news,” said the CDC’s Mark Thompson, the study’s lead author. “We have a vaccine that’s working very well.”
The study is the government’s first assessment of how the shots have been working beyond the drugmakers’ initial experiments. Results can sometimes change when vaccines are used in larger, more diverse populations outside studies.
Vaccine eligibility opening up across U.S.
More than a dozen states will open vaccine eligibility to all adults this week in a major expansion of COVID-19 shots for tens of millions of Americans amid a worrisome increase in virus cases and concerns about balancing supply and demand for the vaccines.
Meanwhile, the director of the Centers for Disease Control and Prevention said Monday that she had a recurring feeling of “impending doom” about a potential fourth wave of infections after cases in the U.S. rose 10% over the last week. She pleaded with Americans not to relax preventative practices such as social distancing and mask-wearing.
“Just please hold on a little while longer,” Dr. Rochelle Walensky said during a White House briefing. Several Northeastern states and Michigan have seen the biggest increases, with some reporting hundreds or thousands more new cases per day than they were two weeks ago.
A new study by the CDC concluded that the Pfizer and Moderna vaccines were 90% effective after two doses, a finding that Walensky said should offer hope.
States opening eligibility to anyone ages 16 and older on Monday included Texas, Oklahoma, Louisiana, Ohio, North Dakota and Kansas.
President Joe Biden announced that by April 19 at least 90% of the adult U.S. population would be eligible for vaccination — and would have access to a vaccination site within 5 miles of home. Quick vaccination would still depend on supply.
