How long does it take to develop immunity to mumps after vaccination with MMR?
In one study 86.6% of vaccinees had evidence of mumps seroconversion at 4 weeks after immunization and 93.3% had evidence of seroconversion after 5 weeks. However, seroconverion may not result in immunity. About 80% of persons who have received 1 dose can be considered protected and 90% after 2 doses.
