There's a lot of whooping cough (pertussis) around at the moment and babies who are too young to start their vaccinations are at greatest risk.
Young babies with whooping cough are often very unwell and most will be admitted to hospital because of their illness. When whooping cough is particularly severe, they can die.
Pregnant women can help protect their babies by getting vaccinated – ideally at 20 weeks, after the foetal scan, up to 32 weeks pregnant. If for any reason you miss having the vaccine, you can still have it up until you go into labour.
