From 1 September 2024, pregnant women can have a free vaccine in each pregnancy to protect their babies against respiratory syncytial virus (RSV). Make sure you are up to date about this important new vaccination to raise awareness and promote uptake.
Why the RSV vaccine is needed
RSV is a common virus which can cause a lung infection called bronchiolitis. In small babies this condition can make it hard to breathe and to feed. Most cases can be managed at home but around 20,000 infants are admitted to hospital with bronchiolitis each year in England. Infants with severe bronchiolitis may need intensive care and the infection can be fatal in some cases. RSV is more likely to be serious in very young babies, those born prematurely, and those with conditions that affect their heart, breathing or immune system.
RSV accounts for approximately 33,500 hospitalisations annually in children aged under 5-years-old. It is a leading cause of infant mortality across the world and results in 20 to 30 deaths per year in the UK. RSV infects up to 90% of children within the first 2 years of life and frequently re-infects older children and adults.
How the RSV vaccine protects babies
The vaccine boosts the mother’s immune system to produce more antibodies against the virus. These antibodies then pass through the placenta to help protect babies from the day they are born. RSV vaccination reduces the risk of severe bronchiolitis by 70% in the first 6 months of life. After this age, babies are at much lower risk of severe RSV.
Older children and adults can also get RSV infection, but the disease is more serious for small babies and people aged 75 and over.
