I have been hearing some great things about Ivermectin.  In the part of the world I am in a person can just walk into a pharmacy and buy Ivermectin for a very low price.  I have also talked to people who have had first had experience with this drug and said it is very effective.  I am not sure where the world is going but it sure would be handy to have this stuff on hand.  It is likely that there will be “new strain” or newly released bio-weapon and there are many anti-viral drugs that are much more effective than any vaccine.  I would say be ready for the fall with some Ivermectin and some hydroxychloroquine.
