FDA Approves Jynneos Smallpox and Monkeypox Vaccine

Share

FDA has approved Bavarian Nordic A/S’s Jynneos smallpox and monkeypox vaccine, live, non-replicating, who are determined to be at high risk for smallpox or monkeypox infection. It is the only FDA-approved vaccine for preventing monkeypox disease.

The agency says that Jynneos will be available for those determined to be at high risk of either smallpox or monkeypox infection. It is also part of the Strategic National Stockpile, the nation’s largest supply of potentially life-saving pharmaceuticals and medical supplies for use in a public health emergency that is severe enough to cause depletion of local supplies.

Jynneos’ safety was assessed in more than 7,800 individuals who received at least one dose of the vaccine. The most commonly reported side effects were pain, redness, swelling, itching, firmness at the injection site, muscle pain, headache, and fatigue. FDA says no safety concerns that would require a Medication Guide have been identified for Jynneos. It is administered in two doses given four weeks apart.

FDA gave the application priority review and with the approval issued a material threat medical countermeasure priority review voucher to Bavarian Nordic.
