You absolutely cannot get influenza from the influenza vaccination unless you did the live intranasal administration. You can get a mild flu like illness for a few days which is just your immune system reacting and mounting an immune response. You can still get influenza regardless of vaccination, though symptoms are lessened. You can also get thousands of other respiratory viruses that people refer to as “the flu” without actually swabbing and checking for influenza. Also young healthy people die of influenza every year. I work in pulmonary and see it every year and it’s the worst part of my job. I hate it when we can’t save them and I have to tell that to their spouse and young kids or parents. It tears me up. It is just not right.
