Pennsylvania Governor Tom Wolf wants to find out if the state can use federal funds to help extend its limited supply of monkeypox vaccine. Last week, the governor said the state is checking to see if it can buy a different kind of needle for the vaccine. To conserve the limited vaccine supply, the FDA has given providers emergency approval to administer shots between the skin to get five doses out of a one-dose vial. The shots require a specific type of syringe, whose cost might be covered by the federal government.
