Vaccines are pharmaceutical products that come with risk that can be greater for some people. No vaccine is safe for everyone. If you choose to vaccinate, ask eight questions before you do. Number one. Am I sick right now? Getting vaccinated while sick could increase risks for a vaccine reaction or lower vaccine effectiveness. Number two. Have I had a bad reaction to a vaccination before? Getting re-vaccinated after a previous vaccine reaction could cause a more serious reaction, injury or even death. Number three. Do I have a personal or family history of vaccine reactions, neurological disorders, severe allergies or immune system problems? Always review your personal and family history when evaluating vaccine benefits and risks.
