Janssen Ad26. RSV. preF Vaccine Description for 2022

Janssen Ad26. RSV. preF Vaccine uses its innovative vaccine technology platform®. This technology is based on the development and production of adenoviral vectors (for transfer of hereditary material) which can activate the immune system to stimulate immunity against the virus.

According to the CDC, Respiratory Syncytial Virus Infection (RSV) was discovered in 1956 and has since been recognized as one of the most common causes of childhood illness. It causes annual outbreaks of respiratory illnesses in all age groups. In most regions of the United States, RSV usually circulates during fall, winter, and spring, but the timing and severity of RSV season in a given community can vary from year to year. 

Although most children will be infected by RSV within the first year of life, adults are also susceptible to the virus. Usually, the illness is mild however some adults may have severe symptoms consistent with a lower respiratory tract infection, such as pneumonia. 

Janssen Ad26. RSV. preF Vaccine has been tested in several clinical trials with older adults. Positive results from the Phase 2b CYPRESS study have led to the initiation of a Phase 3 EVERGREEN study.
