MCQs in Vaccinations And Immunization


Q 1:

The mother of five children asks for advice regarding her third child, a 10-year-old boy who has severe cerebral palsy and lives in a residential institution. The physician at the institution has recommended a yearly influenza vaccine, but the mother is concerned that her son is fragile and would become ill from the vaccine.
Of the following, your BEST recommendation is that the boy receive:

A. a divided dose of the whole virus vaccine
B. antiviral prophylaxis at the start of the influenza season
C. no vaccine until there is a documented influenza virus infection in the residential home
D. the split-virus vaccine prior to the influenza season
E.  the whole virus vaccine only if the strains in the community match the influenza vaccine offered that year

Answer

D


Children who live in residential institutions for the developmentally disabled should receive routine childhood immunizations and an annual immunization against influenza as recommended. Immunization against influenza is important because the infection can spread rapidly in an institution, and these children are more likely to have complications with the infection.

            The influenza vaccine is available in three different forms: the inactivated whole virus and the subvirion and purified surface antigen vaccines (two forms of the “split-virus”). The split-virus vaccine should be used in children younger than 12 years of age because it is associated with a lower incidence of side effects in this age group. Either whole virus or split-virus vaccine can be administered to adults and adolescents. Children younger than 9 years who have not received the vaccine previously require administration of two doses 1 month apart.
