The data is also based on people who received just a single dose of the vaccine.
Health officials have seen protection from monkeypox for those vaccinated with Jynneos as early as two weeks after the first dose, Walensky said.
Still, she said laboratory studies show that immune protection is highest two weeks after the second dose of vaccine, so they are continuing to strongly recommend people get two doses of Jynneos spaced out 28 days apart.
