However, HA can change to evade previously acquired immunity either by antigenic drift, whereby mutations of the currently circulating HA gene disrupt antibody binding, or by antigenic shift, with the virus acquiring an HA of a new subtype by re-assortment of one or more gene segments.
In addition to bacteria, when you're in a hospital, you're also at risk of acquiring a virus and not just a case of hospital-acquired sniffles.
