Oregon's health care workers always go the extra mile. Even the snow did not stop these Josephine County health workers from making sure no vaccines were wasted, vaccinating drivers waiting for the road to be cleared in an impromptu clinic on Highway 199.
A COVID‑19 vaccine is a vaccine intended to provide acquired immunity against COVID‑19. Prior to the COVID‑19 pandemic, work to develop a vaccine against the coronavirus diseases SARS and MERS had established knowledge about the structure and function of coronaviruses; this knowledge enabled accelerated development during early 2020 of varied technology platforms for a COVID‑19 vaccine. By January 2021, 69 vaccine candidates were in clinical research, including 43 in Phase I–II trials and 26 in Phase II–III trials In Phase III trials, several COVID‑19 vaccines demonstrated efficacy as high as 95% in preventing symptomatic COVID‑19 infections. As of January 2021, nine vaccines have been authorized by at least one national regulatory authority for public use: two RNA vaccines (the Pfizer–BioNTech vaccine and the Moderna vaccine), three conventional inactivated vaccines (BBIBP-CorV from Sinopharm, BBV152 from Bharat Biotech and CoronaVac from Sinovac), three viral vector vaccines (Sputnik V from the Gamaleya Research Institute and the Oxford–AstraZeneca vaccine), and one peptide vaccine. Many countries have implemented phased distribution plans that prioritize those at highest risk of complications, such as the elderly, and those at high risk of exposure and transmission, such as healthcare workers. As of 14 January 2021, million doses of COVID‑19 vaccine had been administered worldwide based on official reports from national health agencies.[3] Pfizer, Moderna, and AstraZeneca predicted a manufacturing capacity of billion doses in 2021, which could be used to vaccinate about 3 billion people (as the vaccines require two doses for a protective effect against COVID‑19). By December, more than 10 billion vaccine doses had been preordered by countries,with about half of the doses purchased by high-income countries comprising only 14% of the world's population
