Come Monday, I'll have Jan ask his boss about the vaccine. Perhaps there's
more than one type, like the "killed" vs. the "live" polio vaccines. You
could catch polio from the old "live" oral vaccine, if you hadn't already
been vaccinated. Perhaps once the population has all been vaccinated, as
in the human population with polio, the vaccination is effective, but putting
a vaccinated animal in with non-vaccinated is disaster? Just speculating.
I'll let you know when I find out anything.
