Strictly speaking, a hominid is considered as a general term corresponding for Homo, Pan and Gorilla. If this pertains to the genus Homo (class Hominini), then we only have one species left called Homo sapiens (modern humans) which developed from the ancestors called Homo erectus or Neanderthals. However, hominid could also mean the gorillas and chimpanzees belonging to another genus called Pan (class Hominini) and Gorilla (class Gorillini), respectively.
Answer:
Immunity from vaccination is not as effective as the natural immunity.

Explanation:
Influenza is an infectious disease caused by influenza viruses, which can be divided into four types A, B, C and D. In humans, influenza A and B viruses are known to cause epidemics, while A viruses are known to cause pandemics. Influenza viruses are also found in birds and mammals (e.g., dogs, cats, cattle pigs and horses). Cross-species virus transmission refers to the transmission process of infectious viruses between hosts from different species. Several viruses that may cause severe diseases in humans have originated from animal species, e.g., avian influenza A virus that can be transmitted to humans through an intermediate host (e.g., pigs). Other examples of cross-species virus transmission include the Ebola virus and Hantaviruses. It has been suggested that cross-species transmission is a common phenomenon in rapidly evolving viruses.
