FDA approves GSK's MMR vaccine, the first new green light in more than half a century

GSK is bringing one of its widely-licensed vaccines to the US, giving pediatricians a new option for a common childhood shot for the first time in more than 50 years.

The FDA approved GSK’s measles, mumps and rubella vaccine for individuals 12 months and older, the company announced Monday morning. Branded as Priorix, the shot had already been licensed in more than 100 other countries before coming to the US.
