I have had a compromised immune response (Asthma). I have been in a position to go into bronchitis and could go into pneumonia from a simple cold, if I didn't use antibiotics

I learned a few years ago about zinc, vit D and vit C, playing an integral part in combating infections of the lungs and now do not have a problem. I got through the coof even with little problem, thankfully.

It isn't unbelievable to me, that people can easily die from any sort of simple infection that others can fight off easily

.BTW, no doctor ever told me how to take care of infections by using these simple remedies

I don't discount antibiotics, I just don't use those as a go to first response anymore.
