Sharp drop since 2024 in country regarded as a Latin American leader in childhood and adolescent immunisation
Argentina’s childhood and adolescent vaccination rates have collapsed to historic lows, according to a new analysis, prompting warnings that once-eliminated diseases may resurge.
The study of health ministry data by the Argentinian Paediatric Society (SAP) found that fewer than half of children aged five and six received several of their essential doses in 2024. All vaccine rates analysed were below the 95% level needed to reach herd immunity.
