once a decade, even without a shot. It's not something you can really measure in one year.

So how are they measuring it? Especially when the stats are averaging less than 50 percent effectiveness of the vaccine itself over the last 15 years? They are just using the stats of people who come in and get treatment? They ask them if they had the shot? I'm guessing.

But then I'm reading studies saying that yearly flu shots are making people less protected than say someone who just had their first shot in 5 years.

I'm not saying to not get it. Just that it has a lot of unanswered questions
