A webpage on Natural News claims that it is a bad idea to get a flu shot because certain flu shots contain antibiotics. It says:
The flu vaccines contain antibiotics such as neomycin, polymyxin B and gentamicin which are added to eliminate stray bacteria found in the mixture. Evidence shows that antibiotics wipe out beneficial bacteria that is needed for optimum health. Antibiotics ironically lower the immune system and cause Candida overgrowth.
Do flu shots contain antibiotics and if so, does that make them harmful to your health?
