“Tell the truth, present the data,” said Dr. Paul Offit, a vaccine expert and adviser to the Food and Drug Administration. “I have to believe that there is a way to explain these things so people can understand it.”
Knowing which groups of people were being hospitalized in the United States, which other conditions those patients may have had and how vaccines changed the picture over time would have been invaluable, Dr. Offit said.
Relying on Israeli data to make booster recommendations for Americans was less than ideal, Dr. Offit noted. Israel defines
severe disease differently than the United States, among other factors.
“There’s no reason that they should be better at collecting and putting forth data than we were,” Dr. Offit said of Israeli scientists. “The C.D.C. is the principal epidemiological agency in this country, and so you would like to think the data came from them.”
It has also been difficult to find C.D.C. data on the proportion of children hospitalized for Covid who have other medical conditions, said Dr. Yvonne Maldonado, chair of the American Academy of Pediatrics’s Committee on Infectious Diseases.
The academy’s staff asked their partners at the C.D.C. for that information on a call in December, according to a spokeswoman for the A.A.P., and were told it was unavailable.
Dr. Nordlund pointed to data on the agency’s website that includes this information, and to multiple published reports on pediatric hospitalizations with information on children who have other health conditions.
The pediatrics academy has repeatedly asked the C.D.C. for an estimate on the contagiousness of a person infected with the coronavirus five days after symptoms begin — but Dr. Maldonado finally got the answer from an article in The New York Times in December.
“They’ve known this for over a year and a half, right, and they haven’t told us,” she said. “I mean, you can’t find out anything from them.”
