Currently, the Walgreens system allows people to book their appointment for a second dose, but they can only do so the day before the appointment.
“I’m not happy about that,” said Ms. DeTurris Poust. “It gives me an extra week not to be protected, so that means there’s another week that I’m worried about catching it from someone or giving it to someone.”
Some public health experts said they were not concerned about Walgreens planning four-week doses.
“It’s a weekly difference. Everyone will have to put it in their context and in their risk factors, but I think that̵
But other experts said they were concerned.
“It’s not the role of a private company with the ideal goal of making public health decisions that need to be determined by guidelines issued by a public health authority,” said Lawrence Gostin, a global professor of health law at Georgetown University.
Dima Kato, a pharmacist and associate professor at the School of Pharmacy at the University of Southern California, said she was concerned about how the public perceived conflicting reports about the distance between doses of the same vaccine.
“As we try to build trust in this pandemic, I think it may repel us,” Dr. Kato said.
Walgreens is not the only vaccine provider to make a second shot a little later than recommended. Others in the country have been doing so for months, especially in the early days of the launch, when vaccine supplies were limited and sites had little clarity on which vaccines and how many doses they would receive in the coming weeks, said Tinglon Day, a researcher at Johns Hopkins University. “.
