Why vaccinate during pregnancy?
Vaccination during pregnancy helps protect both you and your baby from serious infections.
These pregnancy vaccines are carefully chosen to protect you while you're pregnant - and to pass on protective antibodies to your baby before they’re even born.
-
Vaccines work by teaching your immune system how to recognise and fight certain germs.
They contain a harmless version of the germ (or just part of the germ), so your body can safely build protection without you getting sick.
Once your immune system learns what to look for, it remembers how to fight it off in the future.
-
Young babies are especially vulnerable to some infections because their immune systems are still developing, and they haven’t yet had their own vaccinations. That’s why giving your new baby early protection by getting vaccinated while you are pregnant is so important.
During pregnancy, protective antibodies made by your immune system cross the placenta, to your baby. When you're vaccinated during pregnancy, this boosts the level of antibodies in your blood and increases how much can be passed to your baby before birth. These antibodies protect your baby from infection in their first few weeks of life, before they’re old enough to get their own vaccines.
Even if you have been vaccinated before, getting your recommended vaccines in every pregnancy maximises protection for your baby.
