Can measles vaccine cause measles? Yes, but hopefully a milder case of spots
Did you know that 38% of the 194 cases of measles that were sequenced by CDC in the 2015 outbreak were vaccine strains?
“Of the 194 measles virus sequences obtained in the United States in 2015, 73 were identified as vaccine sequences (R. J. McNall, unpublished data).”

The authors were from the US CDC, Canada’s National Microbiology Lab in Winnipeg and Germany’s Robert Koch Institute. The high number of vaccine strain cases had not been published by CDC, at least at the time this paper came out in 2017.
Parents should be made aware of this additional side effect of measles vaccination.
