By figuring out how a common virus hides from the immune system, scientists have identified a potential vaccine to prevent sometimes deadly respiratory infections in humans.

The research was conducted using the human metapneumovirus (HMPV). The virus was discovered in 2001, but follow-up research has shown that it has circulated in humans for at least 50 years and is considered around the world to be the No. 2 cause of respiratory infections that can be especially dangerous for infants and the elderly.
HMPV is in the same family as respiratory syncytial virus (RSV), the No. 1 cause of human respiratory infections that can also cause serious illness in infants and the elderly—which means these findings may hold promise for development of a vaccine against RSV.
“This is exciting because RSV was discovered in 1953, but we still don’t have a…
