My first came as a result of the common cold.
The second was after heart surgery, caught it quick,
The third was from I don’t know where. I just developed a cough that lasted for weeks, then when I coughed up a brown phlegm I knew what it was and went straight to the doctor.
Now I get the vaccine.
My granduncle caught it many years ago from trail dust while on a cattle drive. the doctor treated it with kerosene back then.
Have you had your vitamin d3 status checked?
If not, do so.
If you supplement, look into taking or eating foods with vitamin K2. Ask your doc before supplementing with that.
I used to get pneumonia several times a year, from common colds and even seasonal allergies. Since supplementing with d3 I haven’t had pneumonia in 7 years now. Also helps ameliorate cancer risk.
