This is quite an interesting topic. I am from Kerala state of India which has probably lowest child mortality rates, extended life expectancy, zero cases of polio and 100% literacy. ( I don't necessarily agree to all these figures as numbers and reality will vary. But this gives a slight picture). There are numerous other issues like unemployment, lack of any industries, lack of skilled labor they have all migrated to other countries.

Why I gave this introduction is to share the surprising resistance towards vaccinations that happened recently for a Measles-Rubella (MR) vaccination . ( http://www.thenewsminute.com/article/measles-rubella-vaccine-drive-starts-kerala-experts-speak-about-safety-and-necessity-56817 ) It took me by surprise as I have seen multiple vaccinations drives in the past and people in this region has wholeheartedly supported such drives. I think religious propaganda, exposure to media and alternate opinions etc is creating such varying opinions. In India Whatsapp vidoes and facts plays a major role in deciding what people do and form opinions as per my observation. Now the articles I quoted not share my view point or I don't have enough knowledge to say yes or no in this particular vaccination program. In general to reach an opinion I read supporting research from PubMed, avoid pseudo scientific ones and try to form an opinion or leave it. This comment is just to raise awareness that such cases are everywhere, even with places which are known for literacy freedom of expression etc as well.
