Operation Warp Speed (OWS) was a public–private partnership initiated by the United States government to facilitate and accelerate the development, manufacturing, and distribution of COVID-19 vaccines, therapeutics, and diagnostics. The first news report of Operation Warp Speed was on April 29, 2020, and the program was officially announced on May 15, 2020. It was headed by Moncef Slaoui from May 2020 to January 2021 and by David A. Kessler from January to February 2021.

The Oxford–AstraZeneca COVID‑19 vaccine, sold under the brand names Covishield and Vaxzevria among others, is a viral vector vaccine for the prevention of COVID-19. It was developed in the United Kingdom by Oxford University and British-Swedish company AstraZeneca, using as a vector the modified chimpanzee adenovirus ChAdOx1. The vaccine is given by intramuscular injection. Studies carried out in 2020 showed that the efficacy of the vaccine is 76.0% at preventing symptomatic COVID-19 beginning at 22 days following the first dose and 81.3% after the second dose. A study in Scotland found that, for symptomatic COVID-19 infection after the second dose, the vaccine is 81% effective against the Alpha variant and 61% against the Delta variant.

SARS-CoV-2, the virus that causes COVID-19, was isolated in late 2019. Its genetic sequence was published on 11 January 2020, triggering an urgent international response to prepare for an outbreak and hasten the development of a preventive COVID-19 vaccine. Since 2020, vaccine development has been expedited via unprecedented collaboration in the multinational pharmaceutical industry and between governments. By June 2020, tens of billions of dollars were invested by corporations, governments, international health organizations, and university research groups to develop dozens of vaccine candidates and prepare for global vaccination programs to immunize against COVID‑19 infection. According to the Coalition for Epidemic Preparedness Innovations (CEPI), the geographic distribution of COVID‑19 vaccine development shows North American entities to have about 40% of the activity, compared to 30% in Asia and Australia, 26% in Europe, and a few projects in South America and Africa.
Post-vaccination embolic and thrombotic events, termed vaccine-induced immune thrombotic thrombocytopenia (VITT), vaccine-induced prothrombotic immune thrombocytopenia (VIPIT), thrombosis with thrombocytopenia syndrome (TTS), vaccine-induced immune thrombocytopenia and thrombosis (VITT), or vaccine-associated thrombotic thrombocytopenia (VATT), are rare types of blood clotting syndromes that were initially observed in a number of people who had previously received the Oxford–AstraZeneca COVID‑19 vaccine (AZD1222) during the COVID‑19 pandemic. It was subsequently also described in the Janssen COVID‑19 vaccine, leading to the suspension of its use until its safety had been reassessed. On 5 May 2022 the FDA posted a bulletin limiting the use of the Janssen Vaccine to very specific cases due to further reassessment of the risks of TTS, although the FDA also stated in the same bulletin that the benefits of the vaccine outweigh the risks.

A COVID-19 vaccine card is a record often given to those who have received a COVID-19 vaccine showing information such as the date(s) one has received the shot(s) and the brand of vaccine one has received, sometimes including the lot number. The card also contains information identifying the recipient and the location where the shot was given. Depending on the country, it could serve as an official document verifying one has received vaccination, which could be required by some institutions, such as a school or workplace, when boarding a cruise ship, or when crossing an international border, as proof that one has been vaccinated.
A vaccine passport or proof of vaccination is an immunity passport employed as a credential in countries and jurisdictions as part of efforts to control the COVID-19 pandemic via vaccination. A vaccine passport is typically issued by a government or health authority, and usually consists of a digital or printed record. Some credentials may include a scannable QR code, which can also be provisioned via mobile app. It may or may not use a COVID-19 vaccine card as a basis of authentication.
