The immunity developed by a mother after vaccination during pregnancy is passed on to her baby in the womb. This immunity helps protect the baby during the first few months of life.
Vaccines recommended in pregnancy
Whooping Cough Vaccine
Women should get whooping cough vaccine during each pregnancy. between week 16 and 36 of your pregnancy (you can have it after 36 weeks but it’s less effective)
Whooping cough (also known as pertussis) is highly contagious and can be life-threatening for babies.
Getting the whooping cough vaccine protects you and your baby.
Flu Vaccine
The flu vaccine is inactive and can be given safely at any time during pregnancy.
A pregnant woman who gets the flu is at risk for serious respiratory illness and complications. Getting flu in pregnancy can also so lead to premature birth and smaller babies. Flu vaccination during pregnancy provides immunity against influenza infection to babies in the first 6 months of life.

Covid-19

You should also get your first round of COVID-19 vaccination or any booster doses you are due to protect yourself from the virus.

COVID-19 vaccines are safe for you and your baby. They protect you from getting very unwell if you get COVID-19.

Most pregnant women who get COVID-19 get mild to moderate symptoms. They give birth as planned and the risk of passing on COVID-19 to their baby is low.

But pregnant women are more likely to get very unwell and need treatment in intensive care than a woman who is not pregnant. The virus may also cause complications for your baby.

Children under the age of 1 are at higher risk of hospitalisation and severe illness from COVID-19. Young babies whose mothers were vaccinated in pregnancy, were less likely to need hospital care with COVID-19.

Getting a COVID-19 vaccine during pregnancy gives you and your baby the best possible protection from COVID-19.

During pregnancy immunity to rubella is checked routinely. MMR vaccination is only required if you do not have documentation of having had at least one MMR vaccine in the past.
