Humans fail to develop lasting immunity to Norovirus due to high mutation rates
the verdict
SUPPORTED
the evidence backs this
confidence 81/100
Genomic evolution and high mutation rates in norovirus capsid proteins drive antigenic changes, enabling the virus to evade prior immunity and cause repeated infections.
