Pfizer’s New Vaccine, Abrysvo, Protects Newborns from Respiratory Syncytial Virus (RSV)
Pfizer, one of the leading pharmaceutical companies, has recently developed a groundbreaking vaccine called Abrysvo to safeguard newborns against the respiratory syncytial virus (RSV). This virus is a common cause of lung infections in infants and can lead to severe respiratory illnesses.
The newly approved vaccine works by administering it to pregnant individuals during late pregnancy. By doing so, protective antibodies pass through the placenta and onto the developing fetus, providing crucial defense against RSV. This innovative approach has shown promising results in clinical trials, reducing the risk of lung infections by approximately 57% within the first six months of an infant’s life. Moreover, it offers a remarkable 76.5% protection against severe RSV infections.
The U.S. Food and Drug Administration (FDA) granted approval for Abrysvo in August, and it has now been recommended by the Centers for Disease Control and Prevention (CDC). This approval marks a significant milestone in the fight against RSV.
To ensure optimum protection, the CDC suggests administering the vaccine during and in preparation for the RSV season, which typically occurs from late fall to early spring. It is recommended to receive the vaccine between weeks 32 and 36 of gestation. Dr. Mandy Cohen, the CDC’s director, urges parents to engage in discussions with their healthcare providers to consider either the maternal RSV vaccine or an RSV immunization for their baby after birth.
Although there is currently no approved RSV vaccine specifically designed for infants, antibody drugs are available to offer protection. The CDC advises that most infants will likely only require protection from either the maternal RSV vaccine or infant immunization, but not both.
With the introduction of Abrysvo and its approval by the FDA and endorsement by the CDC, there is renewed hope for the prevention of RSV among newborns. This breakthrough vaccine not only reduces the risk of lung infections but also provides substantial protection against severe cases. As the medical community continues to advance in combatting RSV, it is crucial for parents to consult their physicians regarding the best preventive measures for their little ones. Stay informed and protect your loved ones from respiratory syncytial virus.
