The CDC and FDA ensure the safety of vaccines through rigorous testing. Highmark’s Preventive Schedule recommends vaccinations based on factors such as age, gender, and health history. The flu shot, a crucial defense against the flu, is recommended for everyone over 6 months old. With a strong safety record, the flu vaccine cannot cause the flu, offering protection and helping to reduce the spread of symptoms to others. ACSHIC members must receive vaccinations at their PCP’s office.
