With flu season looming, medical professionals encourage you to get the flu vaccine early. Dr. Mark Engelman says contrary to some conspiracy theories, the shot itself does not make you sick, although you may feel a little unwell. He likens it to firefighters responding to an alarm.
The vaccine’s not the only way to fend off the flu and other illnesses, though. Dr. Engelman says a healthy diet and exercise are important to keeping your immune system in peak condition. For those who take vitamin C, he says get most of it from your daily diet. Supplement it with not more than a gram or two a day to avoid oversaturation.
