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.
The rapid expansion has fueled concerns that the number of eager vaccine seekers will far outstrip the available supply of shots, frustrating millions of newly eligible people who have waited since late last year for a chance to get an injection.
Other officials have put their faith in a promised glut of vaccines and instead turned their attention to the next challenge: pressing as many people as possible to get the shots so the nation can achieve herd immunity at the earliest opportunity.
Vaccination rates in Texas have lagged behind much of the U.S., and although state officials put at least part of the blame on delays in data reporting, they also acknowledged that appointment slots are going unfilled.
Demand “has definitely decreased over the past couple of weeks,” said Imelda Garcia, head of the state’s expert vaccine allocation panel.
Texas is supposed to receive more than 1 million new doses this week. On Monday, the state launched a new online vaccine scheduler and phone number, taking a bigger role in efforts that had largely been done at the local level.
In Kansas, where some local health officials have said they are also struggling to find people to vaccinate, an additional 400,000 people are now eligible for shots.
Democratic Gov. Laura Kelly has been criticized by Republicans for a slow, disorganized vaccine rollout, and she faced more criticism Friday when she announced the plan to expand eligibility.
