Just one flu vaccine shot: Protects mothers throughout pregnancy and their babies during the first six months of life

Flu vaccination during pregnancy not only helps reduce the risk of influenza infection and prevent severe complications for the mother throughout pregnancy but also provides the baby with a valuable immune shield from birth. Through the transfer of maternal antibodies, the vaccine helps protect infants during the first six months of life – a period when they are still too young to receive the flu vaccine themselves.

Why should pregnant women get the flu vaccine?

During pregnancy, a woman’s immune system becomes naturally suppressed to prevent rejection of the fetus. As a result, expectant mothers are more vulnerable to influenza infection and its serious complications. Studies show that the hospitalization rate due to influenza in pregnant women is eight times higher than in non-pregnant women.

A single flu infection during pregnancy can lead to pneumonia, respiratory failure, or even encephalitis—all of which pose significant risks to both the mother and the developing baby. Moreover, influenza during pregnancy has been linked to preterm birth, stillbirth, and emergency cesarean delivery. Receiving a full dose of the flu vaccine greatly reduces these risks, helping to ensure a safer and healthier pregnancy.

Flu vaccination not only protects the mother but also provides early protection for the newborn. In the first six months of life, infants are not yet eligible for flu vaccination. However, when the mother is vaccinated during pregnancy, protective antibodies are transferred through the placenta and later through breast milk, forming a passive immunity shield that helps protect the baby against influenza during this critical early stage.

This means that with just one vaccination, the mother not only protects herself but also gives her baby a healthy start in life, significantly reducing the risk of flu infection during the first few months – when the baby’s immune system is still very fragile.

The best time for pregnant women to get the flu vaccine

According to recommendations from the World Health Organization (WHO) and the Vietnam Ministry of Health, the inactivated flu vaccine (which does not contain live virus) is completely safe for both the mother and the fetus.

If you are planning a pregnancy, it is best to receive the flu vaccine at least one month before conception to help your body build protective antibodies early in pregnancy.

If vaccination was not done before pregnancy, expectant mothers can still be safely vaccinated at any stage of pregnancy. However, the optimal time is during the second trimester (weeks 13 to 27), when the risk of side effects is lowest while still ensuring effective protection for both mother and baby.
