Pretty much what Tiger said happens. Here are some facts of the matter ! Take your Vitamin C every day! I haven't had a cold in years ! I'm glad too as it really messes with my bronchitis !
What happens to your body when a cold or flu virus invades | Metro ...
I agree with Tiger and Rooster.
I had a Vitamin C packet daily, its packed with 7 minerals.
Get your Flu and Pneumonia shots early (I had both two days ago).
Stay away from sick folks and practice good body and dental hygiene.
I can't remember the last time I had the flu or a cold.
