Do you know how many people died before introduction of influenza vaccine ?
if the drug company just want to cheat people money and influenza vaccine is not effective, how about other vaccines?
If you think vaccines are not effective you just simply do not receive vaccines
DO NOT regret if you got any illness:lol (include hepatitis, chickenpox, measles,mumps, rubella,tetanus....these vaccines are produced by same drug company as influenza vaccines)
Mind you once a highly infectious and fatal disease (include death of some Ching Dynasty Emperors):small pox was successfully eliminated from the world since 1980 by vaccines,otherwise nowadays you and I still under the threat of this horrible disease.
If you want to save money is up to you but please do not use other ridiculous excuse
If you do not know the exact effect of infuenza vaccine you better search more reliable information before making a ridiculous conclusion
