Monkeypox virus: US health officials unveiled a new vaccination plan.

The Biden administration unveiled a new plan to vaccinate eligible Americans against monkeypox, prioritizing those who have been exposed to the virus in states with the highest infection rates.

Hundreds of thousands of doses of the Jynneos vaccine from Bavarian Nordic A/S will be made available under the administration’s new plan through a tiered-allocation system, the US Department of Health and Human Services said Tuesday.

“Our goal right now is to ensure that the limited supply of Jynneos vaccine is deployed to those who can benefit from it almost immediately, as we continue to secure additional vaccine doses,” HHS Assistant Secretary for Preparedness and Response Dawn O’Connell said in a statement.

The administration plans to allocate 296,000 Jynneos doses in the coming weeks, including 56,000 that will be available immediately, according to a release.
