Warning that even though the vaccine has a high efficacy for preventing EV71-associated hand, foot and mouth disease, it might play a small part in reducing the overall incidence of hand, foot and mouth, even by universal mass immunization of children.

"This virus has caused a fairly severe outbreak in the Sydney metropolitan region over the past six months, with many children admitted to hospital, some with life-threatening disease. A very high level of protection is demonstrated by this study in the short term (about a year follow up) and it will be important to determine longer-term protection," he said.
