Otitis media og bronkospasmer blev indberettet signifikant hyppigere blandt modtagere af vaccine end blandt modtagere af placebo; blandt de tilfælde, der efter forsøgets forskers opfattelse kunne anses for vaccine- relaterede, var forekomsten af otitis media (0, 3%) og bronkospasmer (< 0, 1%) imidlertid den samme for modtagere af vaccine og placebo.
Otitis media and bronchospasm were reported in significantly more vaccine than placebo recipients overall; however, among cases that were considered to be vaccine-related in the opinion of the study investigator, the incidence of otitis media (0.3%) and bronchospasm (< 0.1%) was the same for vaccine and placebo recipients.
