Health experts at NHS England have urged eligible pregnant women to get vaccinated against respiratory syncytial virus (RSV) ahead of winter to protect their newborns.
Australia experienced its highest-ever number of RSV cases last year, and NHS officials have said that the Australian winter is often a good predictor of how viruses will spread in England. Since the beginning of 2025, the virus has been steadily spreading, with nearly half of reported cases occurring in children under the age of five.
