Many of the viruses and bacteria that historically caused illness, disease and even death can now be effectively avoided through the widespread use of vaccines. Vaccinations are preparations of inactivated or weakened forms of bacteria or viruses. Administration of these vaccines to an individual allows the patient’s immune system to learn to fight and kill the virus or bacterium without the patient suffering from the illness normally associated with that organism.
Not all vaccinations are recommended while expecting. When deciding on vaccination safety during pregnancy, the guidelines are that live weakened viruses are not recommended while dead or inactivated viruses or bacteria are generally considered safe. If you have any specific questions about the need for a vaccine or its safety during pregnancy, feel free to discuss them further with your doctor.
If pregnant, the Cedar City Institute of Women’s Health recommends the administration of the influenza vaccination during flu season (October through May) and the TDAP vaccination during the last trimester of pregnancy if a patient has not previously been given TDAP in the past.
The following link to the Centers for Disease Control contains up to date recommendations for which vaccinations are recommended during pregnancy and which are best to be avoided.
