Microorganisms and Disease The influenza vaccine is administered each year because mutations in the viral hemagglutinin may allow the virus to evade the immune response elicited by previous vaccines it is a polysaccharide vaccine that does not confer long-term protection None of these the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time mutations in the viral hemagglutinin may allow the virus to evade the immune response elicited by previous vaccines it is a polysaccharide vaccine that does not confer long-term protection None of these the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time ANSWER DOWNLOAD EXAMIANS APP
