Getting the flu during pregnancy is one of the biggest fears of pregnant women, especially in the first 3 months of pregnancy. The flu virus not only puts the fetus at risk of birth defects, but high fever combined with the toxicity of the virus can also stimulate uterine contractions, leading to miscarriage or premature birth.

Tetanus vaccination for pregnant women is essentially a pre-exposure vaccination to create antibodies for the mother to avoid infection during childbirth, supporting the baby's body to help minimize tetanus infection when cutting the umbilical cord. Therefore, it can be said that tetanus vaccination for pregnant women is a way to protect the overall health of both mother and child.
