Hi dr , i get flu shot every year but i still have been sick by the others spread disease. please tell me what kind of vitamins i can take to avoid the sickness. thank you ?

Common cold: Good Morning, I dont believe there is any vitamin out there that will prevent sickness from the common cold or flu. Best prevention is to continue to get vaccinate yearly, practice good hand hygiene, get plenty of sleep (7-8 hours per night) and eat a healthy well balanced diet with plenty of fruits and vegetables. Taking a multi vitamin daily is fine, but it is unlikely to prevent any cold.
