Yes, Dr. Gregory House had a small nugget of wisdom to impart - mommie's immunities protect baby for the first 6 months. So if mommie was vaccinated as a child, great. If not, not so much great. Anyway, reason #1 to go ahead and decide to vaccinate. Also, weird, mutated measles spore stuck in your brain and waiting to explode until you're 17 is... bad. But apparently, not fatal!
