If you’re pregnant, you’ll be offered the RSV vaccine. It will help protect your baby against serious illness from RSV infection.
The respiratory syncytial virus (RSV) vaccine is offered during pregnancy. It helps protect your baby against serious illness caused by RSV infection.
RSV is a common respiratory virus. In most people it causes a mild illness with cold-like symptoms. It’s highly infectious and spreads easily when people with the virus cough or sneeze.
In Scotland, RSV is the most common reason that babies are admitted to hospital with respiratory (breathing) problems.
Those who are at highest risk of severe illness from RSV infection include:
Older children and adults can also get infected with RSV. The disease is more serious for young babies.
RSV infection is more common in winter, but can happen at any time of year.
RSV can lead to bronchiolitis. This condition causes small airways (bronchioles) in the lungs to become infected and inflamed.
Bronchiolitis is a common reason why babies under 1 are admitted to hospital. Over 1,500 were admitted to hospital with bronchiolitis in Scotland last winter.
You’ll be offered the RSV vaccine if you’re pregnant. It’ll help protect your baby against serious illness from RSV infection.
During pregnancy, you can get the RSV vaccine from 28 weeks. Having the RSV vaccine at this time means that your baby is protected even if they’re born early.
If you did not get the RSV vaccine at 28 weeks, you can still get it later in your pregnancy. It’ll still protect you from infection and reduce the risk of passing RSV infection to your newborn baby.
The best way to protect your baby from serious illness is getting all recommended vaccines at the right time.

The RSV vaccine is also offered to older adults.
The Abrysvo vaccine is offered in Scotland. It’s usually given as an injection in your upper arm.
The Abrysvo vaccine is not a live vaccine. It does not cause RSV infection.
There are very few people who cannot have the RSV vaccine.
You should not get the vaccine if you’ve had a severe allergic reaction (anaphylaxis) to:
You can view the ingredients in the Abrysvo vaccine patient information leaflet.
It’s important to tell the person giving you the vaccine if you:
You only need 1 dose of the RSV vaccine, even if you’re having multiple births (like twins or triplets).
If you get pregnant again in the future, you’ll need to get another dose of the vaccine at that time.
The RSV vaccine boosts your immune system, which then produces more antibodies against the virus. These antibodies then pass through the placenta to your baby. This helps protect your baby from the day they are born.
The vaccine has been shown to reduce the chance of your baby becoming very ill from RSV.
Like all medicines, no vaccine is 100% effective. If you have the vaccine, your baby may still get RSV. However, their RSV infection should be less severe.
If you get the RSV vaccine during pregnancy, the chance of your baby developing a serious infection caused by RSV reduces by over 80%.
In a clinical trial of almost 4,000 women, the vaccine had a good safety record. It’s now been approved by medicines regulators in the UK, Europe and the USA. Many thousands of women have since had the vaccine in national programmes. This includes more than 100,000 women in the USA.
The clinical trial compared pregnant women who received the vaccine with those that had not. Slightly more babies were born early in the group that had the vaccine than in the group who had not had the vaccine. It’s thought that this difference is due to chance, and that there is not a link between vaccination and early birth. However, this is why the vaccine is being given from 28 weeks rather than earlier in your pregnancy.
Overall, it’s still safer for you and your baby to have the vaccine than to risk your baby getting an RSV infection.
All medicines (including vaccines) are tested for safety, quality and effectiveness before they’re allowed to be used. Once they’re in use, the safety of vaccines continues to be carefully monitored.
You should be offered the RSV vaccine around your 28 week antenatal appointment.
Speak to your midwife to find out the local arrangements for vaccination. They’ll be able to advise you on how to get your vaccine.
It’s normal to experience side effects after the vaccine. These are usually mild. They may include:
You can report suspected side effects of vaccines and medicines through the Yellow Card Scheme.
