malaria is super effective  entire worlds supply of ivermectin was given to african kids to combat malaria it no longer works! malaria parasite is now immune   =rss 10% of african kids with malaria have worms that are totally immune to ivermectin these kids are maybe going to die, african malaria has 33% death rate however men with sickle cell anemia become immune to malaria because to parasite dies after getting exposed to their mutated blood sickle cell anemia severely limits what you can do with your life but since it eliminates malaria the gene responsible for it has survived to this day
