Margaret Keenan's second COVID-19 vaccine
- maker:
- Pfizer Incorporated


















Empty vial that contained the second dose of the Pfizer / BioNTech vaccine against COVID-19 given to the first individual vaccinated in the UK's mass vaccination campaign, Margaret Keenan, on 29th December 2020, LOT EJ1688, Expiry date 03/2021
The COVID-19 vaccine created by Pfizer in collaboration with BioNTech was developed, tested and approved in less than a year. It works by introducing into the body a messenger RNA (mRNA) sequence that contains the genetic instructions for the vaccinated person’s own cells to produce the vaccine antigens and generate an immune response – priming the body for a COVID-19 infection. It was the first vaccine using mRNA technology to be approved for human use.
Vaccines are widely credited for their role in reducing the spread of the virus, diminishing the severity of illness and lowering incidences of death caused by COVID-19. The vaccine was approved in the UK by the Medicines and Healthcare products Regulatory Agency (MHRA) on 2nd December 2020, becoming the first COVID-19 vaccine approved for general use. This vial contained Margaret Kennan's second dose, after she received her first at the start of the UK's vaccination role out on 8 December 2020. At the time, doses were recommended to be three weeks apart but advice from the Joint Committee on Vaccination and Immunisation (JCVI) changed on 30 December 2020 to make vaccines more accessible to a wider number of people on the priority list.
