Smallpox could be very bad. I was teaching a seminar for some of my Japanese students who were going overseas for home stays, and some of them were interested in why they had to get “ yellow cards” but others didn’t. I started to explain and suggest that vaccinations for things like meningococcus were good even for countries like the US. They got hung up on the word “vaccination”, so I showed them my smallpox scar. None of my students had one, and then I realized that almost no one has gotten one for almost 40 years.
‘___________no one has gotten one for almost 40 years.’
Believe it’s over 40 years - closer to 45-plus.
