The reform expands the list of mandatory vaccines for children in the Principality, marking the first substantial change to legislation since 1992.
Health Minister Christophe Robino presented the bill, stressing that vaccination remains one of the most effective tools for protecting children and maintaining a resilient healthcare system.
The previous framework, based on a 1970 law last amended over three decades ago, was deemed out of step with current medical knowledge.
While several vaccines previously only recommended will now become obligatory, the HPV vaccine will remain voluntary after detailed discussions between the government and lawmakers.
Robino noted its proven safety and effectiveness – preventing up to 90% of precancerous lesions and cervical cancers, and reducing other HPV-linked cancers in both men and women – but confirmed Monaco will continue with its incentive-based, school-focused vaccination campaigns rather than making the jab compulsory.
The bill also introduces a mechanism allowing mandatory vaccinations to be suspended by sovereign ordinance, though any suspension will now be limited to 18 months unless extended by parliamentary vote.
Government officials thanked elected representatives for advancing the text, acknowledging that legislating on compulsory vaccination is never simple despite broad agreement on its public health benefits.
