Natural immunity???? My wife is allergic to wasp stings, on one of her visits to her PCP she pointed out that she should be building up an immunity to the wasps. Not so said the doctor you don't build up immunity, it just gets worse. Right now you can control it with OTC pills but many more encounters will require an epipen (sp) and could result in death. Where the heck is her immunity? You don't feed peanut butter to someone who is allergic to nuts.
Another point on another thread it was pointed out that the vaccine is not a vaccine but is altering your DNA so said a Bogus Biologist.. What? If that's the case all the labs with their DNA databases are worthless since you can change your DNA by getting the vaccine. Think of the advantage that criminals will have. No longer can your DNA be used as proof. Just get a vaccine and you now have different DNA. But, you may no longer be related to a famous person and could have a serial killer in your ancestoral line.
