With this, not entirely true. Polio still exisit in other parts of the world, so if your friend *bob* went to a polio infected area and became a carrier, when he would come home and visit, your children can become infected (yes rare, but more then 0%)

There are high risk vaccination centers open that might be an option for when your ready later incase you didn't know



Love MN ;-)
I should have been more clear. While the risk isn't actually 0%, it's higher than that, it's such a small number like 0.000something% that it's classed at "statistically" 0%.
