Vaccination Schedule and Dosing Regimens for JYNNEOS Vaccine1

  • JYNNEOS vaccine is approved for the prevention of mpox and smallpox disease.
  • The standard regimen for JYNNEOS involves a subcutaneous route of administration with an injection volume of 0.5mL. In the context of the current national Public Health Emergency, an alternative regimen involving intradermal administration with an injection volume of 0.1mL may be used under an Emergency Use Authorization (EUA).
  • People can be vaccinated after exposure to mpox virus to help prevent mpox disease (i.e., post-exposure prophylaxis).
  • No data are currently available on the clinical efficacy or effectiveness of JYNNEOS vaccines in the current outbreak.
  • Because there are limitations in our knowledge about the effectiveness of these vaccines in the current outbreak, people who are vaccinated should continue to take steps to protect themselves from infection by avoiding close, skin-to-skin contact, including intimate contact, with someone who has mpox.
  • Globally and in the United States, supply of JYNNEOS vaccine is currently limited, although more is expected in the coming weeks and months. In the United States, there is a large supply of ACAM2000, but this vaccine has more side effects and contraindications. Hence, it will not be used by the Centers for Disease Control and Prevention (CDC).
