Prevention of respiratory syncytial virus disease across the lifespan in Italy.

Abstract

Respiratory syncytial virus (RSV) causes substantial morbidity and mortality across the lifespan, with the highest burden seen in infants and older adults. Recently approved immunizing agents, including long-acting neutralizing monoclonal antibodies and a maternal vaccine for passive immunization of newborns, and three vaccines for adults aged 60 years and older who are vulnerable to RSV disease, have the potential to prevent severe RSV-associated disease if implemented successfully. The use of these agents will be implemented in some Italian regions over the next few months, although no consistent timelines or decisions for adoption at the national level are expected. A multidisciplinary group of experts in neonatology, obstetrics and gynecology, respiratory medicine, geriatric medicine, hygiene, and public health reviewed the evidence on RSV prevention and present here their considerations on implementing an RSV prevention strategy in Italy. Given the associated disease burden, it is essential to move quickly to deploy these agents in vulnerable populations, enhance surveillance to accurately detect/predict seasonal trends in RSV activity and measure the impact of prevention strategies. Continuing research combined with widespread use of more sensitive testing is needed to identify vulnerable populations and risk factors. Policies are needed to support these preventive measures in the Italian healthcare system, and access must be accompanied by educational initiatives and advocacy to promote acceptance by HCPs and the target population.
