Unlike diseases such as measles, mumps or chicken pox, the flu virus is constantly changing. Every time it changes, it becomes a new type of flu virus. These different types of flu viruses are called “strains.” A flu shot that protected you last year may not protect you against this year’s new strain. When you get the flu shot, you prevent yourself from getting sick, as well as you friends and family members.
Therefore, it is important that you and your family get your flu shot every flu season. The flu season usually starts in early September or when kids go back to school. Getting a flu shot also helps prevent you from having to take time off work because you or someone you care about is sick. It also prevents you from spending money on medicine you otherwise wouldn’t need. Flu shots are especially important for children and the elderly, because their bodies are not as good at fighting infections. Flu shots should be available at your family
doctor’s office, your local Walgreens or CVS pharmacy.
