If you are at high risk of hepatitis B, for example because you work in healthcare, you may be offered the hepatitis B vaccine. The hepatitis B vaccine is considered safe during pregnancy.

A study looking at the health of 1339 people vaccinated during pregnancy, and their babies, found that having a hepatitis B vaccine while you are pregnant does not increase the chance of pregnancy loss, pregnancy problems or health problems for your baby.  

Some travel vaccines are made with a live, but weakened, version of the germ they are designed to protect you against. These vaccines are not recommended during pregnancy because there is a small potential risk that this kind of vaccine could cause your unborn baby to become infected. It is recommended that you avoid visiting countries where these vaccinations are required while you are pregnant, if you can. 

If you cannot avoid travelling to one of these areas, talk to a doctor or midwife, who can tell you about the risks and benefits of any vaccinations you might need. If there is a high risk of infection in the area you are travelling to, it may be safer to have the vaccine than travel unprotected.
