The NHS’s top midwife is urging newly eligible pregnant mothers that “now is the time to act” and get the RSV vaccine to protect their baby ahead of this winter.
Respiratory syncytial virus (RSV) is a leading cause of infant mortality around the world and a main cause of child hospitalisations every year – with almost 7,000 bed days taken up by children with RSV last winter in England (6,815 from 25 November 2024 – 30 March 2025).
The Australian winter is often a good predictor of how viruses will spread in England, and following the highest number of RSV cases on record last year in Australia, cases have been steadily increasing since the start of 2025 in many areas, with almost half of RSV cases in children aged 0 to 4 years.
England’s chief midwife is urging eligible pregnant women from 28 weeks to speak to their maternity services about getting vaccinated to ensure their babies are protected ahead of their first winter months.
Kate Brintworth, chief midwifery officer for NHS England, said: “While for most adults RSV only causes mild, cold like symptoms, for older adults and young children it can lead to serious breathing problems that can end up in hospitalisation.
“Getting vaccinated while pregnant is the best way to protect your baby from the moment they are born, and now is the time for mums to act, to make sure their babies are protected ahead of their first few months this winter, when there tends to be more bugs circulating.”
The RSV vaccine was offered to pregnant women in England for the first time last September and has now helped to protect more than 300,000 mothers and babies.
Thanks to the hard work of GP and maternity services, vaccination teams and pharmacies across the country, NHS staff have now delivered more than two million RSV vaccinations to eligible people since the rollout kicked off (2,061,474).
Pregnant mums from 28 weeks onwards can access the RSV jab through their maternity services or via their local GP practice. Older adults aged 75 to 79 years old are also eligible, and across the coming weeks NHS England will send invites to over one million people via letter, text, email or NHS App notifications, to remind those eligible to come forward.
Health Minister Karin Smyth said: “I am proud that this government introduced the RSV vaccination programme for pregnant women last year, to protect babies against this disease.
“Getting the RSV vaccine while pregnant is the most effective way to protect your newborn from getting seriously ill with RSV in their first few months of life.
“That is why I encourage everyone who is eligible for the vaccine to come forward when asked, or contact your maternity service or GP practice to make an appointment from week 28 of pregnancy, to help give your child the best possible start in life.”
New research from the UK Health Security Agency (UKHSA) has found the RSV vaccine is around 82% effective in preventing older people being hospitalised with an RSV infection, and another study by NHS paediatricians found that the maternal vaccine is 72% effective in preventing hospitalisation for newborns whose mothers are vaccinated more than 14 days before delivery.
Greta Hayward, Consultant Midwife at the UK Health Security Agency, said: “Having the RSV vaccine during every pregnancy is the best way for women to protect their newborn against RSV, as the vaccine boosts their immune system to produce more antibodies against the virus, and these then pass through the placenta to help protect their baby from the day they are born. RSV infects around 90% of children in their first two years of life.
“The RSV season usually starts in October and while there is no risk-free birth month, babies born in late summer or the autumn are most likely to be admitted to hospital. Hundreds of babies attend Emergency Departments each day for bronchiolitis through most of November and December. That is why it is so important that over the summer pregnant women reaching 28 weeks of pregnancy, ensure they are vaccinated as soon as possible.”
Around 100 community pharmacies in the East of England and the Midlands are also now delivering the RSV vaccine, with NHS England planning to expand this offer to up to 150 additional pharmacies across the country, focusing on areas where access is limited to make it as easy as possible for eligible people to receive their jabs.
Many of the additional community pharmacy sites will also be offering the pertussis (whooping cough) vaccine to eligible pregnant women, helping to improve uptake and free up GP appointments each year.
