Answers to common questions about RSV and vaccination while pregnant

Is my baby at risk for RSV?

RSV is the #1 reason why babies are hospitalized. Almost half of RSV-related hospitalizations in babies happen in the first 3 months of life. RSV can cause inflammation in the lungs, which may make it hard for your baby to breathe.

Infants and young children are at higher risk for RSV if they:

• Are born prematurely
• Are under 6 months of age
• Are less than 2 years old with chronic lung disease or heart disease present from birth
• Have weakened immune systems
• Have neuromuscular disorders including difficulty swallowing or clearing mucus from the chest

What could happen if my baby gets RSV?

RSV may cause a baby to develop a severe wet cough, wheezing, difficulty breathing, or even pneumonia. Babies who become sick with severe RSV may need to be admitted to the hospital. There is a risk that babies who become sick with RSV may have problems with their lungs later in life including asthma.

What can I do to help protect my baby against serious respiratory disease caused by RSV?

Babies are most vulnerable to getting sick from RSV during their first 6 months of life. That's because a baby's immune system isn't fully developed when they are born and needs time to grow stronger. One way to help protect newborn babies is to vaccinate pregnant women during weeks 32 through 36 of pregnancy. Pfizer’s ABRYSVO^® is the only RSV vaccine given during pregnancy, from 32 through 36 weeks, that helps protect your baby against serious respiratory disease caused by RSV, from birth through 6 months.

Is there a time of year when my baby is at a higher risk of getting RSV?

The CDC recommends ABRYSVO if you are 32 through 36 weeks pregnant during RSV seasons—September through January in most of the U.S. However, there are areas in the U.S., including Florida, Alaska, Hawaii and the U.S. territories, where RSV does not follow typical seasonal patterns and the recommended months for maternal vaccination may differ.

Talk to your OB-GYN to learn more about how to protect your baby against RSV during their first RSV season and whether ABRYSVO is right for you.

How does getting vaccinated with ABRYSVO while pregnant help protect my baby?

Pfizer’s ABRYSVO helps your body create RSV antibodies that are passed from you to your unborn baby. These antibodies help protect your baby against serious respiratory disease caused by RSV, from birth through 6 months.

How was Pfizer’s ABRYSVO studied in pregnant women?

ABRYSVO was studied in a clinical trial including over 7,000 pregnant women and their babies, where 3,698 pregnant women received ABRYSVO and 3,687 received a placebo.

If I’m pregnant, when should I get Pfizer’s ABRYSVO?

The CDC recommends ABRYSVO if you are 32 through 36 weeks pregnant during RSV season—from September through January in most of the U.S. However, there are areas in the U.S., including Florida, Alaska, Hawaii and the U.S. territories, where RSV does not follow the typical seasonal patterns and the recommended months for maternal vaccination may differ.
