The Iowa Department of Public Health and Safety said the state asked the federal government to withhold 71% of the 105,300 vaccine doses that were available for the week of May 10. This is the second week in a row that the state has asked the federal government to hold back part of its allocation of vaccine doses.

Department spokeswoman Sarah Ekstrand told the Des Moines Register that 88 of Iowa's 99 counties have told the state they don't need all or part of their weekly vaccine allocations for that week. That's an increase from the 80 counties that declined vaccine shipments for this week and the 43 counties that declined all or part of their allocations last week.
