Having worked in several countries with terrible sanitation, and having had close contact with people maimed by polio, I am very upset about your comment. While sanitation is having a huge impact, your dismissal of the importance of vaccinations is simply outrageous.
To be clear: vaccinations are not only an additional option besides better sanitation. They are the only thing which can lead to an eradication, which is overdue.
And if you insist on alleging that the decline of polio, and the possible worldwide eradication are just coinciding with vaccination, we have serious beef, you and I.
