Vax Facts Friday 12.19.25
Q: What type of vaccine is the MMR vaccine?
A. Conjugate vaccine
B. Live, “weakened” viral vaccine
C. Toxoid vaccine
D. Inactivated viral vaccine
The correct answer is B. Live, “weakened” viral vaccine
The MMR vaccine is a live, “weakened” viral vaccine that contains three vaccines (measles vaccine, mumps vaccine and rubella vaccine) combined into one shot. All three vaccines are made by weakening the viruses so that they do not replicate enough to cause disease but still reproduce enough to provide protective immunity.
