The 25,000 HHS employees who will be required to get vaccinated are concentrated within the Indian Health Service and National Institute of Health, as well as the U.S. Public Health Service Commissioned Corps.
The deadline to get vaccinated is the end of September, according to an HHS official familiar with the plan. There will be exemptions for religious or medical reasons.
