RSV Vaccine for Pregnant Women

Receiving the RSV vaccine provides dual benefits: it protects the mother from infection and also protects the baby. During pregnancy, the mother’s immune system is weaker than usual, so it’s recommended to get the vaccine between 32-36 weeks of pregnancy.

RSV (Respiratory Syncytial Virus) is the most common respiratory virus that causes pneumonia in children. It can lead to severe diseases such as bronchiolitis, pneumonia, and is a leading cause of death in newborns. Every year, 100-300 children under the age of 5 in the United States (mostly under 6 months old) die from RSV infection. Children who get infected with RSV during the first 3 years of life are three times more likely to develop asthma compared to children who did not get infected.

The symptoms are similar to a common cold, such as having a fever for 2-3 days, a runny nose, and a sore throat for about 4 days. However, since pregnant women experience changes in their immune system, they are at greater risk of developing more severe illnesses, such as pneumonia, in over 50% of cases. The risk is higher if there are underlying health conditions such as asthma, heart disease, or respiratory failure, which can be dangerous for the baby. In cases where the pregnant mother contracts a severe infection, it may result in preterm birth, low birth weight, and a small baby.

RSV typically outbreaks during the rainy season (June-August) to the winter season (December-February).

The virus can spread through the air and enter the body via the eyes, nose, or mouth through bodily fluids such as saliva and mucus. Close contact with an infected person who coughs or sneezes, or touching contaminated objects such as door handles, tables, chairs, and toys, can also transmit the virus.

• The vaccine is administered to pregnant women between 32-36 weeks of pregnancy.
• After receiving the vaccine, the body helps to produce immunity, reducing the risk of pregnant women contracting RSV.
• Helps reduce the risk of respiratory diseases caused by RSV infections, complications during pregnancy, and reduces the severity of the disease.
• Helps pass immunity from the mother to the baby, protecting the baby from infection for up to 6 months.

The RSV vaccine can reduce the hospitalization rate of infants from RSV infection by 68% at 3 months and 57% at 6 months. It can also reduce the ICU admission rate for infants from RSV infection by 82% at 3 months and 69% at 6 months.

• In terms of vaccine safety, it can be administered to all pregnant women who have no history of vaccine allergies.
• Common side effects include pain at the injection site, headache, body aches, and nausea, but these symptoms are not severe.
• There is no reported benefit of this vaccine for breastfeeding mothers, so it is not recommended to administer the RSV vaccine to mothers after delivery.

• Get the RSV vaccine during pregnancy between 32-36 weeks
• Avoid contact with individuals infected with RSV, avoid crowded places, and wear a face mask
• Maintain hygiene by eating hot, using serving utensils, and washing hands thoroughly
• Clean frequently touched objects or surfaces
• Get adequate sleep
• Avoid smoking
