It's almost back-to-school time, and that means it's time for immunizations.
The University of Pennsylvania's Dr. Mike Cirigliano joined "Good Day" on Monday morning to talk about how exactly vaccinations work to prevent disease.
First, he mentioned meningitis, which 3,000 to 5,000 people get every year and 1 in 10 die from. It can be fatal even with antibiotics in 25 percent of cases, and the key is protection with immunization.
And more and more cases of measles in the United States are due to lack of immunization, Dr. Mike said.
He tackled whether you can get autism from vaccinations, what he has done with his own son and what he recommends to all of his patients.
