As Monkeypox Cases Rise, Nations Are Urged to Examine Vaccine Stores

As more than a dozen countries grapple with outbreaks of monkeypox, health officials worldwide are rushing to assess reserves of vaccines and treatments that may be needed to contain the spread.

The U.S. emergency stockpile holds two vaccines approved by the Food and Drug Administration that could be used to contain monkeypox, officials at the Centers for Disease Control and Prevention told reporters on Monday.

The stockpile contains more than 100 million doses of the original smallpox vaccine. But that vaccine is associated with side effects and shouldn’t be given to certain patients, including those who are immuno-compromised.

A newer vaccine, called Jynneos, was approved in 2019 for prevention of both smallpox and monkeypox. More than 1,000 doses are held in the stockpile, Dr. Jennifer McQuiston, a deputy director at the C.D.C., said.
