In September 2021, Amnesty International published A Double Dose of Inequality, which assessed the extent to which the pharmaceutical industry was restricting access to Covid-19 vaccines. This report updates that assessment of five leading vaccine manufacturers, AstraZeneca plc, BioNTech SE, Johnson & Johnson, Moderna Inc., and Pfizer Inc. It also includes for the first time an assessment of the two largest Chinese vaccine producers, China National Pharmaceutical Group Co., Ltd. (Sinopharm) and Sinovac Biotech Ltd. (Sinovac).
