Thus, a posting like Mr. Zuckerberg's becomes vital for sending the pro-vaccine message forthrightly — although we would add one caveat. It might also be useful to link to that photograph some trusted and reliable information about childhood vaccinations. Here's one from the American Academy of Pediatrics (aap.org/en-us/advocacy-and-policy/aap-health-initiatives/immunization/Pages/default.aspx). Here's another from the Centers for Disease Control and Prevention (cdc.gov/vaccines/). And, close to home, here's an excellent source of current information on vaccines of all types from Johns Hopkins Bloomberg School of Public Health (vaccinesafety.edu/). Kudos to someone from Silicon Valley for leading the charge, especially given that, according to Wired magazine's review of California's health database, it's a region with a below average vaccination rate. Conservative politicians may chafe at the federal government potentially mandating such preventive care, but if that's what it takes for parents to act in the best interest of their own children — and society as a whole — that may be part of the future, too.
