Vaccines to consider before and during pregnancy

Consider the advice of your health-care professional to ensure that your immunizations are up to date if you are planning your pregnancy.

1. Rubella

Rubella (German measles) can be very dangerous early in your pregnancy and for your unborn baby. Infection can lead to complications such as deafness, cataract, cardiac defect, bone damage, mental retardation, and enlargement of the liver and spleen. Before you conceive, get your immunity to rubella tested. It is often given as a combined measles-mumps-rubella (MMR) vaccine. Because this is a live-attenuated vaccine, it is not given during pregnancy and you should wait at least four weeks after getting the vaccine before trying to conceive.

2. Hepatitis B

Your job, lifestyle or health history may put you at increased risk to become infected with hepatitis B and you should be immunized against hepatitis B if you have not been before. The virus could be transferred to your baby and can pose risks for cirrhosis of the liver and liver cancer.

3. Influenza

Pregnant women are at increased risk of hospitalization and serious complications from H1N1 influenza. The seasonal flu vaccine is safe for pregnant women and is recommended for those who will be pregnant during flu season. Being immunized will also help protect your baby through his or her first few months of life.

4. Tetanus, diphtheria and pertussis

Tetanus and tetanus-diphtheria (Td) vaccines are well-established as being safe for pregnant women. Recently, the Td vaccine has been combined with a pertussis vaccine, known as the Tdap vaccine. Pertussis (whooping cough) can be serious for anyone, but for your newborn, it can be life-threatening and with the vaccine antibodies made by your body will provide your baby with some short-term, early protection against whooping cough.

5. Other vaccines

If you have a history of a chronic liver disease, your doctor may recommend the hepatitis A vaccine. If you need to travel abroad during pregnancy, you should talk to your doctor at least 4 to 6 weeks before your trip to discuss any special precautions or vaccines that you may need. If you are travelling to a country where you may be exposed to a meningococcal disease, your doctor may recommend the meningococcal vaccine.
