Vaccines help protect against monkeypox when given before or shortly after exposure to the virus. The JYNNEOS vaccine is approved by the U.S. Food and Drug Administration (FDA) to prevent both monkeypox and smallpox. It is most effective at preventing monkeypox if the vaccine is administered within 4 days of exposure. When given between 4-14 days after the date of exposure, vaccination may help reduce symptoms but may not prevent the disease from developing.
