An alarming outbreak of the mumps two years ago has raised questions about whether an additional vaccination is needed. A report in The New England Journal of Medicine on Thursday tracks the 2006 epidemic, the largest outbreak in two decades. Mumps had virtually disappeared in America since the 1990s, when doctors began using a second dose of measles-mumps-rubella vaccine among schoolchildren. But most of those who became infected in 2006 were college students who had received the double-vaccination, raising questions about whether a third dose may be needed.
