Vaccination fails to fully protect against viral disease, since it is based on attenuated virus.
The proportion of measles cases who were fully vaccinated (i.e. with two doses of measles-mumps-rubella-containing vaccine) was higher (14 %) than what was observed in France during the much larger epidemic that occurred between 2008 and 2011 (3–4 %).
So the discovery that 52 of the 98 teens who caught measles were fully vaccinated came as a shock to the researchers who conducted the investigation.
Eight HCWs were notified as measles cases; 6 were vaccinated with measles vaccine twice, 1 was vaccinated once, and 1 was unvaccinated.
This is why
The Attenuated virus that in the vaccine, only protects against Attenuated Virus but not against the real virus.
