Pfizer/BioNTech’s Covid-19 vaccine, Comirnaty, has seen a phenomenal increase in its Q3 2021 forecast sales for 2022 and 2023 compared to its Q2 forecasts, with increases of 190% and 228% for 2022 and 2023 respectively, resulting in 2022 forecast sales of $28.4bn and 2023 forecast sales of $13.4bn. Comirnaty is currently the leading prophylactic vaccine for Covid-19 by forecast sales and is expected to generate an unprecedented $100bn in sales from 2020 to 2027, driven by large forecast sales from 2021–2024, according to the Coronavirus Disease 2019 (COVID-19) Sector Forecast: Q3 2021 Global Analyst Consensus Sales report.

Comirnaty was the first globally approved Covid-19 vaccine, approved by the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) on 2 December 2020 by emergency use authorisation (EUA). It has since gone on to become the leading Covid-19 vaccine by sales and was recently granted full approval by the US Food and Drug Administration (FDA) on 23 August. It currently remains significantly ahead of its main rivals, Moderna’s mRNA-1273, AstraZeneca’s Vaxzevria and Johnson & Johnson’s Covid-19 vaccine, by total forecast sales between 2020 and 2027. Only Moderna’s mRNA-1273 forecast sales approach the same level of sales, with forecast sales of $41.8bn between 2020 and 2027, which is still $60bn less than Comirnaty’s $100bn over the same period.
