Parents of school-age kids today probably never witnessed a whooping cough outbreak or the measles because they were lucky enough to have lived in a generation of vaccinated kids. But this luxury of good health could slip away all too quickly as more and more families opt out of routine vaccinations.
If you want to look at the hard facts, the good health of our kids depends on a numbers game.
Preventing kids (and adults) from getting diseases depends on a statistic: As long as about 90-95% of us vaccinate our kids, our kids are relatively safe according to an Associated Press report. Even the un-vaccinated kids are protected because the vaccinated kids keep the disease numbers down. In simple terms, our kids are healthy due to herd immunity.
