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 hydrochloride monohydrate
- magnesium chloride hexahydrate
- polysorbate 80
- 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 chemindustry.com website, Polysorbate80 is a glycol analog.
