Mpox & Variole B: Vaccination Campaign Launched in Réunion

Health officials in Réunion Island have confirmed two cases of Mpox imported from Madagascar, prompting a vaccination campaign to protect vulnerable populations and prevent further spread. The emergence of these cases highlights the ongoing global risk of Mpox and the importance of proactive public health measures.

The first case, confirmed on January 22, involved a Réunion Island resident who recently returned from Madagascar. The individual was isolated, and close contacts were identified for medical monitoring to prevent transmission of the virus. Symptoms began after the individual’s return flight.

A second case was confirmed on February 10, also involving a Réunion Island resident who developed symptoms several days after returning from Madagascar. Authorities state that, at this time, no epidemiological link has been established between this second case and the first confirmed on January 22, 2026. The patient has been placed in isolation, and individuals identified as potential contacts have been informed and offered medical follow-up, including reactive vaccination.

To mitigate the risk of local transmission, the Réunion Island Regional Health Agency (ARS) launched a vaccination campaign against Mpox on February 9, 2026. Vaccinations are available at travel vaccination centers and the sexually transmitted infection (STI) screening and diagnostic center (CEGIDD).

The vaccination campaign includes both preventative and reactive strategies. Preventative vaccination is recommended for individuals at higher risk, including those with weakened immune systems, men who have sex with men, and sex workers. Vaccination is also available, upon medical advice, for individuals traveling to Madagascar or areas with active virus circulation, including healthcare professionals and humanitarian workers.

Reactive vaccination is available to individuals identified as high-risk contacts of confirmed Mpox cases. This vaccination is most effective when administered within four days of exposure, but can be given up to 14 days after exposure.

Vaccinations are available by appointment at three centers on Réunion Island: Saint Paul (CEGIDD Ouest), Saint-Denis (Centre de vaccination international Nord-Est), and Saint-Pierre (Centre de vaccination international Sud).

The vaccine is free for eligible individuals, including those in the high-risk groups mentioned above. Travelers destined for Madagascar or other areas with active virus circulation will have the cost of the vaccine covered only, with other associated costs the responsibility of the traveler.
