The last couple years since I've been faithful in taking multi vitamin, Vitamin C plus allergy pill everyday, I dont get colds.
Hubby who is a school teacher hasnt had a cold in over a year since I started him on the Vitamin C daily. Last year they didnt give teachers flu shots so it was important to get him started on Vitamin C (he takes it year round). Plenty of rest, fluids and exercise keeps us in check.
FYI tid bit....... #1 spreader of germs .... dirty hands.
Prevention of spreading.... wash hands often.
