Vaccines are an important part of a healthy pregnancy. They help protect you and your baby against serious diseases.
Some diseases are particularly harmful to pregnant people and their babies and can cause birth defects, premature birth, miscarriage, and death. Many of these diseases can be prevented through vaccination.
It’s important to know which vaccines you need before, during, and after pregnancy.
- Vaccines before pregnancy
It’s best to make sure all of your routine vaccines are up to date before becoming pregnant. This is important because some vaccines cannot be given during pregnancy but provide important protection. For example, the measles, mumps, rubella (MMR) vaccine should not be given during pregnancy, but rubella infection during pregnancy can cause miscarriage and serious birth defects. If you are planning to become pregnant, talk to your health care provider about vaccines you may need.
It’s also a good idea to make sure that everyone in your household is up to date with their vaccines. This will help protect your baby by lowering the chance of household members getting a disease and passing it onto your baby. This is especially important because babies don’t start getting vaccines until they are two months old, and most vaccines require more than one dose. This means that newborn babies are especially vulnerable to disease. Even though you may not be able to receive certain vaccines while pregnant, it is safe for others in your household to receive routine vaccines during your pregnancy.
- Vaccines during pregnancy
It is recommended that all pregnant people get the pertussis (whooping cough) and influenza (flu) vaccines during each pregnancy to protect themselves and their babies. Other vaccines may be recommended for during preganncy if you're are travelling or at risk for certain diseases.
Influenza (flu) vaccine
Canada's National Advisory Committee on Immunization recommends that all pregnant people at any stage of pregnancy get the influenza (flu) vaccine during the influenza season to protect themselves and their newborns. Pregnant people should receive the inactivated influenza vaccine (given by injection).
What is influenza?
Influenza, often called the flu, is an infection of the upper airway caused by the influenza virus. Influenza spreads easily from person to person through coughing, sneezing, or having face-to-face contact.
Why is the influenza vaccine recommended during pregnancy?
Influenza can be very serious during pregnancy. Normal changes that happen in your body during pregnancy, like changes in your immune system, make you more likely to get really sick from influenza and to be hospitalized.
Influenza can also be harmful to your baby. When you get the influenza vaccine during pregnancy, you can pass protective antibodies to your baby that can help protect your baby for several months after birth. This is important because babies can get really sick from influenza but can’t get the vaccine until they are six months old. If you did not receive the influenza vaccine during pregnancy, you should get it as soon as possible after your baby is born and preferably before discharge from the hospital.
Getting the influenza vaccine during the influenza season will help protect you and your baby.
What is the best time to get the influenza vaccine?
The influenza (flu) vaccine is recommended and provided for free for pregnant people during the influenza season (usually from October to April each year). For best protection, you should get immunized as soon as possible during the influenza season.
Is the influenza vaccine safe in pregnancy?
Pregnant people should receive the inactivated influenza vaccine (given by injection). There is good evidence to show the inactivated influenza (flu) vaccine is safe for pregnant people and their babies.

Flu Shots During Pregnancy
COVID-19 vaccineCOVID-19 vaccination is recommended for all people 12 years of age and older, including people who are pregnant, breastfeeding or who may become pregnant.Pregnant people are at increased risk of serious illness and complications from COVID-19 infection. Vaccines can drastically reduce this risk and can be given safely at any time while trying to conceive, during pregnancy or while breastfeeding.Evidence from around the world continues to grow and has not found any safety concerns for pregnant or breastfeeding people who were vaccinated or for their babies. Studies have shown that pregnant people who get a COVID-19 vaccine receive the same levels of protection that non-pregnant people do, and that this protection can be passed on to your baby.There are currently no known serious risks (such as an increased risk of miscarriage or possible birth defects) when getting a COVID-19 vaccine while pregnant or breastfeeding (or providing expressed human milk) to either the person being vaccinated or the child.The Canadian Society of Obstetricians and Gynaecologists recommends that pregnant or breastfeeding people should be offered the COVID-19 vaccine at any time if they have no symptoms or medical conditions preventing them from getting immunized. There is no evidence to suggest that COVID-19 vaccines will affect fertility or the pregnancy itself.For more information, go to the BC Centre for Disease Control’s COVID-19: planning for your vaccine handout for people who are pregnant, breastfeeding or thinking about getting pregnant.For more information on COVID-19 vaccines, go to our COVID-19 vaccine section.
Pertussis (whooping cough) vaccine
The Tdap vaccine is recommended and provided free to pregnant people in every pregnancy. The vaccine should be given at 27-32 weeks of pregnancy regardless of previous Tdap immunization history but may be given as early as 13 weeks and up until delivery. The pertussis vaccine is given as the tetanus, diphtheria, pertussis (Tdap) vaccine. This will protect newborn infants in BC from severe outcomes related to pertussis infection.
What is pertussis?
Pertussis is a serious infection of the airways caused by the pertussis bacteria. It can cause complications such as pneumonia (an infection of the lungs), seizures, brain damage, and death. Pertussis is most dangerous in babies.
Why is the pertussis vaccine recommended during pregnancy?
Babies don’t start getting the pertussis vaccine until they are two months old. The best way to protect your baby from pertussis and its complications during their first two months of life is to get the vaccine yourself. When you get the pertussis vaccine, your body makes protective antibodies. Antibodies are proteins made by the body to help fight off diseases. You can pass some of these antibodies on to your baby through your placenta before birth. These antibodies will help protect your baby from pertussis during their first couple of months of life. This is when your baby is most at risk of getting pertussis and of having serious complications from it but is too young to get vaccinated.
What is the best time to get the pertussis vaccine?
The best time to get the pertussis vaccine is between 27 and 32 weeks of pregnancy. This allows time for you to pass the protective antibodies on to your baby. However, the vaccine may be given earlier and can be provided up until delivery. Talk to your health care provider about timing.
Is the pertussis vaccine safe in pregnancy?
The pertussis vaccine is very safe for pregnant people and their babies.
Where can I get the pertussis vaccine?
Tdap vaccine will be provided by prenatal care providers including family doctors and midwives, but can also be provided by specialty prenatal care service providers and by community-based pharmacists, or at the local health unit at adult immunization clinics.
In certain situations, other vaccines may be recommended during pregnancy.
- The hepatitis B vaccine is recommended for pregnant people whose jobs, lifestyles, or health histories puts them at high risk of becoming infected with hepatitis B. Your health care provider will let you know if you need the hepatitis B vaccine.
- The hepatitis A, meningococcal, and polio vaccines may be recommended for pregnant people travelling to areas of the world where these diseases are common. Tell your health care provider if you are travelling outside Canada during your pregnancy.
Safety of vaccines during pregnancy
Inactivated vaccines are generally safe in pregnancy. However, live vaccines (for example, the measles, mumps, rubella (MMR) and the chickenpox (varicella) vaccines) should generally not be given during pregnancy because they have not been proven to be safe for pregnant people and their babies.
Your healthcare provider can tell you which vaccines are recommended for you and which vaccines are safe to get during pregnancy.
- Vaccines after pregnancy
If you didn’t catch up on certain vaccines before or during your pregnancy, it’s important that you get them as soon as possible after your baby is born. This will help protect you and your baby, by lowering the chance of you getting a vaccine-preventable disease and passing it onto your baby. It will also ensure you’re protected in future pregnancies. It’s safe to receive vaccines right after birth, even if you are breastfeeding.
