The world greets newborn babies by bombarding them with everything from dust to disease-causing microbes. Babies can deftly parry exposures to certain harmful substances, thanks to antibodies passed onto them in the womb. But this kind of inherited immunity is short-lived, so a child must develop her own immune system response to combat life-threatening diseases. That’s where vaccines come into the picture.

By age two, most children will receive almost 30 shots designed to boost a child’s natural defenses against disease. Yet at the same time, parents who take their children for those recommended vaccinations might be inundated with Web site and celebrity-espoused rumors making false claims that shots are not necessary or cause autism. At best, navigating this landscape can be confusing. But when weighing the risks of encountering life-threatening disease against the benefits of receiving a vaccine there’s no contest. The vast majority of children do not experience anything worse than short-lived redness or itching at the spot of the shot. So why is there so much misinformation?

One reason is developmental timing. Children receive a bevy of vaccines before age two, roughly overlapping with when children with autism spectrum disorder may noticeably develop symptoms like the inability to gain new skills. That coincidence has helped the autism–vaccine connection myth persist. And what may have once been passed around by neighborhood gossip is now amplified worldwide by Web sites and social media. But the science simply does not bear out such fears. In August 2011 the Institute of Medicine (IOM) released a report that examined eight childhood vaccines and potential side effects. It found that vaccines are largely safe and that side effects are usually very rare and minor.
