Whether or not you can get a vaccine while breastfeeding depends on which vaccine you are planning to get. For example, the New Crown vaccine can also be given during breastfeeding, and there is no need to interrupt breastfeeding for this reason. Generally speaking, inactivated vaccines administered during breastfeeding basically do not affect the quality of breastmilk, and will not affect the baby because some vaccines pass through the milk, including influenza vaccine, new crown vaccine, rabies vaccine, chickenpox vaccine, hepatitis B vaccine and so on. But after all, there have been no detailed clinical studies done on many types of vaccines, so if it’s not necessary, try to wait until after breastfeeding to get the shot in case of allergies or other problems. Live attenuated vaccines should be avoided during breastfeeding because relatively speaking, injecting such vaccines may affect the health of the mom or the baby. During the breastfeeding period, if you have to take the vaccine, you need to consult a professional doctor before taking the injection.
