~~~Warning: very long article, but worth reading~~~
A few months ago I was involved in a truly interesting dialogue on Facebook (on a public page) with a young man named Alexandru Ioan Voda, a student in Biomedical Sciences and a PhD student at Oxford. It was a real pleasure discussing with him.
Since the conversation came to an end, I would like to post the essential part of it here for my English-speaking readers and for future reference.
It started after the young man had addressed an acquaintance of mine on the topic of the "measles virus".
