TThe Centers for Disease Control and Prevention (CDC) began sounding the alarm about a potential rise in mpox (formerly monkeypox) outbreaks this summer, just days before publishing studies suggesting that two doses of Bavarian Nordic’s Jynneos vaccine, rather than one, offer “real-world” protection.

The World Health Organization (WHO) on May 11 ended the global health emergency for mpox — less than a week after it ended the COVID-19 emergency.

But on May 15, the CDC issued a health alert, warning that although mpox cases had declined since peaking last August, “the outbreak is not over.”
