Industry spiel:
Antibiotics are used during the manufacturing process of some vaccines to stop bacteria growing and contaminating the vaccine. However, antibiotics which commonly cause allergic reactions (such as penicillins, cephalosporins and sulphonamides) are not used in vaccines.  Traces of five antibiotics may appear in the following vaccines used in the UK. People with a known allergy to any of these antibiotics should ask for expert advice before receiving these vaccines.
Neomycin is used in the production of the MMR vaccines (MMRVaxPro and Priorix), one of the Pre-school Booster vaccines (Repevax), the shingles vaccine(Zostavax) and the chickenpox vaccines (Varivax and Varilrix).
Repevax may also contain traces of streptomycin and polymyxin b.
The Nasal Flu vaccine (Fluenz) may contain a trace of gentamicin.
The MenB vaccine may contain a trace of kanamycin.  ttps://  (copied 21 April 2016)
