You are a perfect example of the ignorance of the question about doubt in science. Because vaccines aren't 100% effective researchers are continuing to research immunology in general and specific vaccines to increase their effectiveness. This is because they DOUBT the effectiveness of the existing vaccines. If you don't believe that vaccines are going to be more effective in one hundred years you are a fool. Science would be neigh impossible if all people did was accept that what is good isn't good enough. I can only assume that you find vaccine denial so offensive that you were unable to read my comment for what it said. I'm the parent of a fully vaccinated three year old because I don't want my kid to die. I have my kid vaccinated for her own sake but also for the safety of those people who are immune compromised. It's completely ignorant to argue that there is no room for rational doubt about the efficacy of childhood vaccines. Telling people not to get vaccines because unsupported autism suspicions that are supported in no way be the data or because your god told you not to use technology that was developed after the 18th century is anti-social and probably immoral. People are so quick to accept what the NY Times science page tells them is fact when it's really just a way station of the path to greater understanding. Doubt is a necessary and essential part of being able to improve and understand our world in the face of new problems and evidence.
