The Janssen vaccine - the commercial name of the Johnson and Johnson manufactured vaccine - was authorised for use by the Medicines and Healthcare products Regulatory Agency on 28 May 2021. At the time of authorisation, no supply was available and none was expected until the end of the year. On 30 October 2021 the Government announced that it would donate all 20 million Janssen vaccines doses it had ordered to COVAX.
Given the maturity of the United Kingdom vaccination programme and strength of existing supplies to meet domestic requirements, the Government was able to identify the Janssen vaccine supply for donation, to be distributed to those most in need overseas. We remain confident that existing stocks of authorised vaccines meet the current requirement for National Health Service and care workers for both the primary course and booster vaccinations.
