Hillary Clinton hits GOP with pro-vaccine tweet

The science is clear: The earth is round, the sky is blue, and #vaccineswork. Let's protect all our kids. #GrandmothersKnowBest

Clinton ends the tweet with a nod to her granddaughter, Charlotte, who was born late last year. Clinton regularly used her grandmother status as a rhetorical tool while campaigning for Democrats in 2014.

Federal health officials have expressed concern over a recent measles outbreak that has been fueled by skepticism among some parents of infant vaccination schedules. Measles is a disease that children a regularly vaccinated against.

Both Obama and Clinton have altered their opinions on this issue, though, because during the 2008 presidential nomination fight, the two left the door open to vaccines causing autism and other issues.

Obama said the science was “inconclusive,” while Clinton wrote in an anti-vaccine questionnaire that she was “committed to make investments to find the causes of autism, including possible environmental causes like vaccine.”
