are acquired by inhalation

The possession of a segmented RNA genome

A limited number of capsule types

None of these

it is a polysaccharide vaccine that does not confer long-term protection

mutations in the viral hemagglutinin may allow the virus to evade the immune response elicited by previous vaccines

the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time
