Ideally, pregnant women should avoid getting vaccines , since antibodies in the virus could harm the fetus.
Live vaccines are particularly risky.
The best rule is to simply avoid traveling during your pregnancy to countries where vaccinations are needed. Of course, you may not be able to avoid going to such places. Others, such as those for malaria or hepatitis B, are less dangerous. When it comes to flu shots , I advise my healthy patients with normal pregnancies to avoid them because they are unnecessary. I do think flu shots are a good idea for pregnant women with medical conditions such as diabetes or a chronic, debilitating illness.
