Antibodies provided by mpox vaccination all but disappear within six to 12 months, new research finds, underscoring the need for boosters to maintain strong protection.

A recent study highlights that mpox vaccine antibodies wane within 6-12 months, emphasizing the need for booster shots to maintain protection against the fast-spreading virus and prevent future outbreaks.

Immunity against mpox may be waning for those vaccinated with the modified vaccinia Ankara-Bavarian Nordic (MVA-BN; Jynneos) vaccine, according to a research letter published online Oct. 3 in the Journal of the American Medical Association.

The first diagnostic test for mpox has been approved by the World Health Organization in a bid to expand its availability and stop the spread of lethal outbreaks of the disease in Africa.

The World Health Organization said Thursday it approved the first mpox invitro diagnostic for emergency use. The Affinity m MPXV assay, made by Abbott Molecular, will expand global diagnostic capacity.

The World Health Organization authorized Abbott Laboratories' mpox diagnostic test for emergency use on Thursday, the first such approval in the agency's effort to bolster testing capabilities in countries facing outbreaks of the disease.
