The flu can be a serious illness that, at worst, may lead to hospitalization or even death. At best, it will make you feel like you’ve been hit by a Mack truck and had your head dipped in a bucket of slop for a few days. The good news is that a seasonal vaccine is available each Fall that can protect you and your family from the most common strains of the flu in any given year. While everyone should consider getting vaccinated, it is particularly important if you are over 65, you have chronic lung disease like asthma or COPD, you have reduced immunity for any reason, or you will be around young children.
