I’ve stopped even trying to get a flu jab after reading that this year’s vaccine is less than 50% effective. Some years it’s completely ineffective.
As someone who knows the difference between a bad cold and flu I know I’ve only had flu three times in a long life.
The vaccine must be changed each year, in hopes of matching the ever-mutating viruses. On average, it's been 40% effective, meaning it's prevented illness 40% of the time.
This doesn't really bother me. I decided last year (age 70) to start to have it. Having had flu only once in my life (I was about 50) I don't want at this age. Even is if it 40% effective.
