evidence: Controlling the growing international monkeypox outbreak will rely on the availability of millions of vaccine doses. But the vaccines are in very limited supply, with people from all over the United States reporting waiting in long lines only to be turned away from clinics, and experts say sufficient doses of the two-dose Jynneos vaccine likely won't be available for months or even years. [...] When monkeypox was first detected in the United States in May, President Joe Biden announced that the United States had enough smallpox vaccine (also approved for monkeypox) in the Strategic National Stockpile (SNS) "to deal with the likelihood of a problem." [...] Monkeypox, Schondelmeyer said, reminds us that it does not work to wait for an outbreak to order the tests, vaccines, and treatments to manage the situation, because drug and vaccine supply chains can take months to years to fill the emergency orders needed now.
