The respiratory syncytial virus (RSV) commonly causes lung and respiratory tract infections in children. It kills or forces the hospitalization of thousands of babies around the world each year. Mayo Clinic researchers suggest that the virus is so common that most children have been infected with it by age two.
Researchers in Chile revealed that they have developed the first vaccine against the RSV. The team said, "After clinical trials can be held it hopes to market the vaccine against so-called RSV in four or five years."
In temperate climates like that of Chile, there are annual epidemics of the virus in winter.
"This virus is very harmful and costly for Chilean society and the vast majority of countries," said Kalergis.
Kalergis further added, "The vaccine has been successful in tests with animals and now the team is ready for clinical trials on people. Assuming we have financing and the results are favorable, we could have a vaccine in four or five years."
