Help protect infants against the risk of RSV from birth

RSV is a highly contagious respiratory virus that can make your baby sick, especially if they’re under 6 months old.

  • Nearly 50% of all RSV hospitalizations during the first year occur during the first 3 months of life.

How does maternal immunization with ABRYSVO protect your baby?

Maternal immunization with ABRYSVO is a choice pregnant women can make to help protect their babies.

  • Maternal immunization with ABRYSVO refers to the process of vaccinating a pregnant woman so protective antibodies can be passed to the baby through the placenta before birth.
  • During pregnancy, your body naturally passes on antibodies that help protect your baby against bacteria and viruses, like RSV, in the first few months of life, before they’re old enough to develop their own protection. Pfizer’s ABRYSVO helps your body create RSV antibodies that are passed to your unborn baby to help protect them from birth through 6 months.
  • Eligible pregnant women can choose to receive Pfizer’s RSV vaccine ABRYSVO between 32 and 36 weeks of pregnancy so that their baby doesn’t have to receive a shot themselves after birth.

Pfizer's vaccine ABRYSVO helps protect your baby against RSV.

ABRYSVO was studied in a clinical trial including over 7,000 pregnant women and their babies, where 3,495 pregnant women received ABRYSVO and 3,480 received a placebo. The study showed ABRYSVO reduced the risk of severe RSV by 69% compared with placebo in infants measured at 6 months after birth.

Ask About Pfizer’s ABRYSVO

Pregnancy is a time when you may have a lot of questions for your doctor. Start the conversation about RSV and Pfizer’s ABRYSVO today.

Is my baby at risk for RSV?

Respiratory syncytial virus (RSV) is the leading cause of hospitalization in infants. The risk of your baby being admitted to hospital with RSV is 16x higher than the flu. RSV is very easily spread to people in hospitals, at home, and in nurseries. The largest group of babies requiring hospitalization due to RSV are those aged less than 6 months old.

Other things that can put infants at risk are:

  • Are born prematurely
  • Are up to 12 months old, especially those 6 months and younger
  • 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 could I do to help protect my baby against RSV?
Babies are most vulnerable to getting sick from RSV during their first 6 months. 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 a vaccine for pregnant women that helps protect your baby against RSV from birth through the first 6 months of their life.
How does getting vaccinated help protect my baby?
Pfizer’s ABRYSVO helps your body create RSV antibodies that are passed from you to your unborn baby, and helps protect your baby from 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 September through January (in most of the continental United States). However, there are areas in the U.S., including southern 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.
