Compound that with the fact many adults don’t actually get the flu that often and it’s not exactly a sure choice for most. I have a terrible immune system and I’ve gotten the flu once as a teen/adult and I’m nearly 35. Apparently the average is 1-2 times a decade. A more effective, longer lasting vaccine would make it a lot more palatable for people.
