Some vaccines are only available on the NHS for groups of people who need extra protection.
During pregnancy, your immune system (the body's natural defense system) is naturally weakened to protect the pregnancy. This may make you less able to fight infections. As your baby grows, you cannot breathe so deeply, increasing the risk of infections such as pneumonia.
These changes can increase the risk of flu - pregnant women are more likely to have flu complications than non-pregnant women, and more likely to be admitted to hospital. Having the flu vaccine means you are less likely to get flu.
Cough is a very serious infection, with young babies most at risk. Most babies with coughs are admitted to hospital.
When you get the cough vaccine during pregnancy, your body produces antibiotics to protect against whooping cough. These antibodies are passed on to your baby and this gives them some protection until he or she is old enough to have their cough vaccine at eight weeks old.
