The flu vaccine is one that is proven to be safe during pregnancy. We strongly recommend that all women who will be pregnant during flu season (November-March) receive a flu vaccine. Vaccines to avoid during pregnancy: MMR, chickenpox, and Lyme disease. The Covid vaccine is safe and effective in pregnancy. Talk to your doctor before receiving any other type of vaccination. Pertussis (whooping cough) vaccine is also recommended during pregnancy. This decreases the likelihood that your baby will contract whooping cough in the first few months of life. It is recommended that all people who will care for the baby have a recent pertussis vaccination.
