Is MMR a live vaccine

Yes! Keep in mind that no drugs, vaccines, or supplements is 100% free of side effects or adverse reactions. Like many things in life, you have to weight to risks versus the benefits. Many people tend to forget how bad were these diseases before the wide spread use of vaccines. Now, because of the vaccines, we don't see these diseases very often, but we do hear people with adverse reactions telling their stories loudly. Just like other things in life, bad news tend to spread like wildfire, but you'd never hear people who didn't have any problems.
