This shouldn't even be a question. Vaccination is arguably the most important medical miracle in all of history. It has saved more lives than all the surgical procedures put together and itnhas done it at very little cost. We have forgotten the horros of small pox, polio, and rubella. A century ago average life expectancy in the US was in the fifties, not because old people didn't live into their 70s or 80s - many did. Because young people died of communicable diseases before ever tasting adulthood and long before they ever had a chance to grow old. We can save many children now who catch measels or rubella, not all of them, but many. And at huge cost in days spent in pediatric intensive care units. Vaccination is cheap, safe, and effective. Those who sound false alarms about vaccine safety are either uninformed, delusional, or profiting from the lie.
