A spokesman for Operation Warp Speed, the Trump administration’s vaccine initiative, released a statement sharply criticizing Mr. Biden’s approach.
“If President-elect Biden is calling for the distribution of vaccines knowing that there would not be a second dose available, that decision is without science or data and is contrary to the FDA’s approved label,” said the spokesman, Michael Pratt. “If President-elect Biden is suggesting that the maximum number of doses should be made available, consistent with ensuring that a second dose of vaccine will be there when the patient shows up, then that is already happening.”
A spokesman for the transition team, T.J. Ducklo, said Mr. Biden “believes we must accelerate distribution of the vaccine while continuing to ensure the Americans who need it most get it as soon as possible.”
“He supports releasing available doses immediately, and believes the government should stop holding back vaccine supply so we can get more shots in Americans’ arms now,” Mr. Ducklo said. “He will share additional details next week on how his Administration will begin releasing available doses when he assumes office on January 20th.”
Dr. Leana Wen, an emergency physician and public health expert at the George Washington University School of Public Health, said she was surprised and concerned about the new strategy, which seemed to offer a solution incongruous with the biggest problems in the vaccine rollout. Distribution has sputtered in large part because of a lack of administering capacity and several logistical hurdles, rather than a severe shortage of doses.
“This is not the problem we’re trying to solve right now,” Dr. Wen said.
For such a plan to work, Dr. Wen added, the Biden administration will need to be confident in both improved distribution tactics and sufficient vaccine production, “so all who receive the first dose of the vaccine will receive the second in a timely manner.”
Should a high number of delayed second doses occur — ostensibly shirking the regimens laid out in clinical trials — “it runs the risk of substantially eroding public trust in vaccines,” Dr. Wen said. The recommended timeframe for administering the second dose for the Pfizer-BioNTech vaccine is 21 days later, and for the Moderna vaccine, 28 days.
