and I've heard rumor that you may weaken your immune system should you introduce articifial help
Well, you should check your sources then. Most vaccinations - especially the
active Influenza vaccination - are no "artificial help" but contain parts or or even complete viruses. Those antigens stimulate your own immune system so by the time the real virus breaches your outter defenses you're ready for it!
Influenza has been a major killer in the history of men. Every 80years (I think) we see a major epidemie. It's a shame that seldom diseases like SARS, Anthrax or even pocks get overdramatasized while we see thousands of casualties by Influenza every year.
It's true the population at risk are children and older people. But also people with heart or lung diseases, people with diabetes or liver problems. Also do not only think about yourself - people who are in constant contact with other, maybe weakend patients, put them at risk also. That's why medical personal, public servicers etc. should be vaccinated as well. And last but not least a high vaccination rate will have a good impact on economy for causing less off days due to sickness.
Vaccines aren't an all-cure-wonder but help holding dangerous diseases at bay. Of course there can be complications - as with all medication. But would you deny yourself anti-biotics in case of a life threatening pneumonia only because there have been reports of allergic reaction or death after ab-injection?
