The Food and Drug Administration (FDA) has authorized the intradermal injection — between layers of skin rather than into body fat — at the request of the Biden administration, just a week after the declaration of a health emergency. “In recent weeks the monkeypox virus has continued to spread at a rate that has made it clear our current vaccine supply will not meet the current demand,” FDA Commissioner Dr. Robert Califf said of the decision. Now just a fifth of the dose is needed per injection, allowing health officials to vaccinate far more Americans. Two doses are still required for full vaccination.
