According to the Cambridgeshire News, UK, the Oxford AstraZenica vaccine contains “the weakened adenovirus encoding the SARS CoV 2 Spike glycoprotein, as well as the following excipients:

  • L-histidine
  • L-histidine hydrochloride monohydrate
  • magnesium chloride hexahydrate
  • polysorbate 80
  • ethanol
  • sucrose
  • sodium chloride
  • disodium edetate dihydrate
  • water for injections”


The full package insert from the UK Medicines and Healthcare Products Regulatory Agency is here as well.

From what i’m seeing on the website, Polysorbate80 is a glycol analog.
