A dose of reality about vaccines…
Subscribe: http://bit.ly/iotbs_sub Twitter: @okaytobesmart
↓ More info and sources below ↓

As more and more parents are choosing not to vaccinate their children or are vaccinating them later, diseases like measles are making a comeback. What's behind this antivax movement? Are vaccines safe? How do vaccines work? Why do some people claim there is a link between vaccines and autism? This week we look at why are people afraid of something that has saved so many lives, and the history and science of vaccines. #vaccine #antivax #measles
