Recent mumps outbreaks in vaccinated populations: no evidence of immune escape.

Rubin SA, Link MA, Sauder CJ, Zhang C, Ngo L, Rima BK, Duprex WP


Recently, numerous large-scale mumps outbreaks have occurred in vaccinated populations. Clinical isolates sequenced from these outbreaks have invariably been of genotypes distinct from those of vaccine viruses, raising concern that certain mumps virus strains may escape vaccine-induced immunity. To investigate this concern, sera obtained from children 6-weeks after receipt of measles, mumps and rubella (MMR) vaccine were tested for ability to neutralize a carefully selected group of genetically diverse mumps virus strains. Although the geometric mean neutralizing antibody titer of the sera was lower against some virus strains than others, all viruses were readily neutralized, arguing against immune escape.
