What a great cause.  My children were both born in a developing nation (Ethiopia) and my son, while a mere 4 months old, nearly died from diarrhea--not something to vaccinate for obviously, but something that simple clean water (so readily available to us) could have prevented.  I have seen first hand the devastation that lack of preventive medical care can cause and vaccines are just that--preventive care that every child should have access too.  

Thank you!
