Vaccines in our FOOD????

[Guest guest]

They have been attempting this POTATO vaccine for several years now.. When

the potato is cooked the vaccine is neutrilized... So it did not work in

the past. Bananas is the method that they are looking at with more hopeful

results.. No one cooks bananas..
