I'm not sure you have a choice!! -if booster vaccination is withdrawn.
The note I read didn't go into details, but I would be concerned about this
virus getting on a plane and arriving in the "Western Hemisphere" before you
can say "Sabin and Salk". Surely vaccination is what is keeping the
infection out of  the W-H?
.....the last time I remember getting a booster is >20yrs ago.

Various people (not usually virologists) have voiced concerns about
rebuilding smallpox from DNA clones....  and suggested that even the clones
be destroyed.
But what happens when the same time comes for polio? You can even make the
virus in a test-tube!!!!!!!!
