Some said they feared the side effects, which can include flu-like symptoms, while others said they felt they were sufficiently protected with a single shot. But a surprising hurdle has also surfaced: A number of vaccine providers have canceled second-dose appointments because they ran out of supply or didn’t have the right brand in stock, the Times reported. Walgreens, one of the biggest vaccine providers in the United States, sent some people who got a first shot of the Pfizer or Moderna vaccine to get their second doses at pharmacies that only had the other vaccine on hand, the newspaper said. Several Walgreens customers said they scrambled to get the correct second dose, but others likely gave up, the newspaper added.
Public health officials had worried from the start that it would be hard to get everyone to come back for their second shot, and now some state officials are scrambling to keep the tally of partly vaccinated people from swelling.
In Arkansas and Illinois, health officials have directed teams to call, text or send letters to people to remind them to get their second shots. In Pennsylvania, officials are trying to ensure that college students can get their second shots after they leave campus for the summer, the Times reported. South Carolina has allocated several thousand doses specifically for people who are overdue for their second shot.
Compared with the two-dose regimen, a single shot triggers a weaker immune response and may leave some people more susceptible to dangerous virus variants, the Times said. And though a single dose provides some protection against COVID-19, it’s not clear how long that protection will last.
While millions of Americans have missed their second shots, the overall rates of follow-through, with some 92 percent getting fully vaccinated, are strong by historical standards, the Times noted. As of Monday, nearly 140 million Americans had received their first shot, while nearly 97.8 million have gotten their second, according to the U.S. Centers for Disease Control and Prevention.
FDA lifts pause on J&J vaccine
The U.S. Food and Drug Administration on Friday lifted the temporary pause it had placed on the Johnson & Johnson COVID-19 vaccine and said it will add a note to the shot’s label warning of the potential for rare blood clots.
The move came just hours after recommendations from a special panel of CDC experts supported resuming use of the vaccine.
