Phlegm Damp is a natural physiological process of secreting phlegm generated by dying bone marrow cells within our skull.
It get deposited (damped) above the neck around the blood vessels and tissues where that process is not visible to naked eye.
It is very rich in nutrients so external bugs like bacteria and viruses can easily grow on it.
So , no matter how much you try to kill the bug (bacteria or virus) you still leave room for new bug to come and grow on it.
So Vaccine can never provide protection from Phlegm Damp Infection or immunity for it.
Only way to solve this is to regulate the irregular inflammation process.
