I’m a virologist in a biotech company in Singapore. Here’s my story: I’ve been interested in infectious diseases since I was a kid, because my father almost died of TB when he was an infant. I must have been the only kid who looked forward to mass vaccination days in school. For a field trip to the Philippines after my bachelor’s and my first job shortly thereafter, I had to be immunized against a lot of other things that the average person doesn’t.
