Parental knowledge about respiratory syncytial virus and attitudes toward infant immunization with monoclonal antibodies in France

In France, the survey respondents had high adoption rates for childhood immunizations. Key drivers behind these high rates were the desire to protect their children from severe diseases and adherence to mandatory immunizations, whereas concerns about safety were the main barriers. While general practitioners and pediatricians were key sources of advice on child health, many parents also requested information about immunizations from health authorities and nurses. Sources of advice varied with parental age, gender, educational level, and income. The majority of parents had no knowledge about mAbs or passive immunization, and the overall awareness of RSV was low. When informed about RSV and mAbs, most parents held neutral to positive attitudes toward nirsevimab for their infants if recommended by a healthcare professional and/or included in the immunization program. These findings were further confirmed by the 60 %-80 % uptake rates of nirsevimab following the introduction in September 2023.
