I get that and accept I was being a little simplistic but it still remains that if someone who has had it then gets a severe attack of the virus it must mean that the vaccine didn't work in the first place.
You shirley cannot say that if a person gets a severe attack after having the vaccine and then recovers that this demonstrates that it works better on people with severe cases than those with mild or no virus problems?
That makes no sense what so ever.
