I want to know the answer to the following question:
When did the Rubella vaccine come out?
All the background I'm provided with is that "Other notable new vaccines of the period include those for measles (1962, John Franklin Enders of Children's Medical Center Boston, later refined by Maurice Hilleman at Merck), Rubella (1969, Hilleman, Merck) and mumps (1967, Hilleman, Merck)". Is that enough to answer the question?
