Vaccine for RSV in Newborns: A Promising Breakthrough
“It’s a vaccine! No wait, it’s a miracle! Well, it’s definitely great news for pregnant women and their babies. Introducing Abrysvo, the newly approved vaccine for respiratory syncytial virus (RSV).” This is the kind of conversation you’ll overhear in the near future as this breakthrough vaccine becomes widely available.
Following approval by the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC) gave their stamp of approval to Abrysvo, placing it on the path to widespread availability. Finally, women can take an extra precautionary step during pregnancy to protect their newborns from RSV, a potentially severe respiratory illness.
Abrysvo can be administered to pregnant women between 32 and 36 weeks of pregnancy, providing infants with protection from birth through their first six months. RSV is a common cause of illness in children, with infants being particularly vulnerable. The approval of Abrysvo offers a new option to shield infants from this life-threatening disease.
The Need for RSV Protection
RSV is more than just a common cold; it can lead to serious lower respiratory illnesses such as pneumonia and bronchiolitis. Infants, especially those in their first year of life, are at the highest risk of severe illness, often requiring hospitalization. In fact, RSV is the leading cause of infant hospitalization in the United States.
However, RSV doesn’t discriminate based on age. People of all ages can be susceptible to this respiratory virus. It’s particularly prevalent in fall and winter, making it a seasonal concern. Most children will have been infected with RSV by the time they reach two years of age.

The Power of Abrysvo
Abrysvo, developed by Pfizer, is expected to be a game-changer in the fight against RSV. If enough women receive the vaccine, it has the potential to prevent 320,000 infant doctor visits and 20,000 hospitalizations each year. And the best part? Clinical trials have demonstrated the vaccine’s safety and effectiveness.
In one trial, around 3,500 pregnant women received Abrysvo, while another 3,500 received a placebo. The results were staggering. Abrysvo reduced the risk of severe illness by nearly 82% within three months after birth, and approximately 69% by the time the baby turned six months old. In a subgroup of pregnant individuals, the reduction in risk for respiratory illness and severe lower respiratory disease was 35% and over 91%, respectively, compared to the placebo.
Safety is also a priority, and Abrysvo’s side effects are minimal. The most common side effects reported were pain at the injection site, headache, muscle pain, and nausea. However, it’s important to note that preterm births showed a numerical imbalance in Abrysvo recipients. While the data is insufficient to establish causation, healthcare providers are advised to be cautious and monitor this aspect closely.
A Step Forward in RSV Protection
Before Abrysvo, the only available option for infants was Beyfortus, a lab-made antibody shot. Yet, the approval of a vaccine for pregnant women provides a proactive approach to protecting the most vulnerable population against RSV.
As Pfizer ramps up production, Abrysvo will become increasingly accessible across the United States. The CDC encourages parents to discuss RSV protection with their healthcare providers and consider either the vaccine during pregnancy or an RSV immunization for the baby after birth.
Now, let’s toast to the birth of a vaccine that can shield newborns from the wintertime woes of RSV. It’s a story worth celebrating, one more step toward a healthier and happier future.
