This is the first I have heard that some medical teams are seeing a pattern emerging.
I am also pro-vaccination, however stopped having the flu vac back in about 2007 after becoming very ill about 3 months post vaccination. On my third year of flu vaccination I noticed a correlation with time frames of illness post flu vac. I don't seem to have a problems with other vaccinations, as a couple of years ago had the whooping cough vaccination with no adverse effects. So decided to stop yearly flu vax, I felt that my immune system got stressed, leaving me vulnerable to picking up a infection.
Since then I have not had any similar illness (pneumonia etc) I have not needed to take antibiotics for secondary bacterial infection for at least 10 years now.
I guess if you have had the flu vax in the past with no issues then that is a bonus.
