It's spread through coughs and sneezes which release the germ into the air, which can then be breathed in by others.
It can cause some people to become seriously ill, and can be very dangerous for infants and the elderly, sometimes causing death. Those most at risk of becoming very seriously ill are:
- babies under 6 months old
- children who were born prematurely
- adults over 75
- people who have a weakened immune system or heart or lung problems
- people who smoke, or babies who are exposed to tobacco smoke
A vaccine has now become available that offers good protection to those who are most at risk from becoming unwell because of RSV infection.
Who can have the vaccine
Older adults
Your GP will usually contact you if you are aged between 75 and 79 years old to invite you for your RSV vaccine.
If you turned 80 on or after 1 September 2024, you're eligible for the RSV vaccine until 31 August 2025.
The vaccine is just a one-off dose for older adults.
People who are pregnant
The vaccine is offered to the pregnant person during their antenatal appointment at around 28 weeks. It's important to have the vaccine around this time for best protection for your baby.
The protection passes from the mother to the baby, so they're more protected from becoming seriously unwell if they get RSV infection. It's important to have the vaccine every pregnancy to help protect each baby.
Where to get the vaccine
Older adults can ge the vaccine through their GP.
People who are pregnant can get the vaccine at maternity appointments.
The vaccine is available all year round.
Protect your baby from RSV infection
To protect your baby from RSV infection:
- take up the offer of the RSV vaccine during pregnancy for best protection for your baby
- for the baby's first few months you can ask people to stay away from your baby if they have a cold
- catching coughs and sneezes with a tissue and getting rid of it and washing your hands or catching coughs and sneezes in the bend of your elbow
- regular handwashing with soap and water
- cleaning toys and frequently touched surfaces regularly
