There has never been a vaccine against coronaviruses for human, and coronaviruses are known since 1920 There have been vaccines against coronaviruses for animals... But their efficacity is average, and in fact, they are more about preventing diseases triggered by a corona infection than preventing the corona infection itself So in the end, it's not a surprise that vaccines turn out to be either lame or totally pointless when it comes to combatting covidXX Sauces https://en.wikipedia.org/wiki/Coronavirus#History >>The earliest reports of a coronavirus infection in animals occurred in the late 1920s >>Vaccines are available for animal coronaviruses IBV, TGEV, and Canine CoV, although **their effectiveness is limited**. In the case of outbreaks of highly contagious animal coronaviruses, such as PEDV, measures such as destruction of entire herds of pigs may be used to prevent transmission to other herds.[50] https://en.wikipedia.org/wiki/COVID-19_vaccine#Background >>Prior to COVID‑19, a vaccine for an infectious disease had never been produced in less than several years – and **no vaccine existed for preventing a coronavirus infection in humans.** [14] However, vaccines have been produced against several animal diseases caused by coronaviruses, including (as of 2003) infectious bronchitis virus in birds, canine coronavirus, and feline coronavirus.[15] Previous projects to develop vaccines for viruses in the family Coronaviridae that affect humans have been aimed at severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). Vaccines against SARS[16] and MERS[17] have been tested in non-human animals.
