Parotitis and aseptic meningitis have been described as complications of mumps vaccination with Urabe, Leningrad–Zagreb and Leningrad-3 strains of the vaccine but not with the Jeryl–Lynn strain1.
The review showed that higher rates of aseptic meningitis and parotitis have been reported for the Urabe, leningrad-zagreb and Leningrad-3 strain vaccines compared to the Jeryl-Lynn strain vaccine.
The Committee further concluded that available data are insufficient to distinguish between the safety profile with respect to aseptic meningitis for Urabe, Leningrad-Zagreb and Leningrad-3 strains.
