What is RSV?

Respiratory syncytial virus (RSV) is a common respiratory virus that can cause severe respiratory illness. It is the leading cause of bronchiolitis and pneumonia in children under 1 year old.

Pfizer's RSV Vaccine Receives FDA Approval

On March 2, 2022, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation to Pfizer's RSV vaccine candidate.

Key Points:

* Pfizer is the only company with a regulatory application for an RSV vaccine for both adults and infants. * The vaccine is intended for active immunization of pregnant individuals at 32 through 36 weeks gestational age. * The vaccine is designed to protect infants from RSV infection during their first few months of life.

How Does the Vaccine Work?

The RSV vaccine is a passive immunization vaccine. It works by introducing antibodies against RSV into the body. These antibodies help protect the infant from RSV infection by neutralizing the virus.

Vaccine Safety and Efficacy

Phase 3 clinical trials of the vaccine have shown it to be safe and effective in preventing RSV infection in infants. The vaccine was well-tolerated, with no serious safety concerns reported.

Conclusion

The FDA's approval of Pfizer's RSV vaccine is a major breakthrough in the fight against RSV. The vaccine has the potential to prevent thousands of cases of RSV infection and hospitalization in infants each year.
