Overview

  • The decision comes after three serious adverse events were reported in individuals over 80, including two cases resembling severe chikungunya and one fatality.
  • The Ixchiq vaccination campaign will now focus on individuals aged 18–64 with comorbidities, as announced by the Ministry of Health.
  • The Direction générale de la Santé (DGS) urgently referred the matter to the Haute Autorité de santé (HAS) on April 24, which recommended revising the vaccination target groups on April 25.
  • The French Medicines Agency has been conducting reinforced monitoring of post-vaccination side effects since April 17, shortly after the campaign began.
  • The chikungunya outbreak, which started in August 2024, has resulted in nine deaths in La Réunion, with transmission rates stabilizing at high levels.
