Testing of samples from the 1950s demonstrated antibodies against this virus, suggesting infections have been common for at least several decades. Studies since have found hMPV in almost all ...

HMPV primarily affects the upper and lower respiratory tracts and is particularly concerning for vulnerable groups.

These immunogens elicit broad and potent hMPV-neutralizing antibodies. Human metapneumovirus (hMPV), a negative, single-stranded RNA virus, accounts for approximately 5-15% of infant respiratory ...
