Gee, it'd be a shame if all these people got exposed to the flu

“In general, due to the short term nature of CBP holding and the complexities of operating vaccination programs, neither CBP nor its medical contractors administer vaccinations to those in our custody,” an agency spokeswoman told The Hill in an emailed statement.

Earlier this month, two top House Democrats wrote to CBP as well as to the Department of Health and Human Services, raising concerns over the spread of influenza in detention centers after at least three children died in U.S. custody, in part, as a result of the flu.

Reps. Rosa DeLauro (D-Conn.) and Lucille Roybal-Allard (D-Calif.) sent the agencies a letter from several Harvard and Johns Hopkins doctors, who asked for a congressional investigation into health conditions at border patrol facilities.

“These tragic deaths appear to represent more than half of child deaths in the last year in these immigration facilities and to reflect a rate of influenza death substantially higher than that in the general population,” the doctors wrote. “Another influenza season is around the corner. … Timely action is critical.”

Once children leave CBP detention centers and are transferred to HHS, they are given full medical screenings upon arrival, as well as any needed vaccinations, including the seasonal flu vaccine, an agency spokesperson said.
