Coronavirus vaccine current status: Oxford vaccine failed in animal trials; here is what happened

As the world puts a joint effort in battling the novel coronavirus, scientists and medical researchers are also working round the clock to develop a vaccine to defeat the highly infectious disease. Typically, a traditional vaccine takes years to develop as it has to go through several levels of clinical trials and needs to be tested for side-effects in the long run. However, as the experts across the globe continue to work at breakneck speed, we already have more than 100 potential vaccines for COVID-19.

The World Health Organization has already identified 7 to 8 top vaccine candidates that are being accelerated and effort is underway to speed up the development of these vaccines. In this race, the vaccine candidate being developed by Oxford University was touted as one of the leading potential vaccines. For their vaccine candidate ‘ChAdOx1 nCoV-19’, the researchers used a weakened strain of common cold virus (adenovirus) that causes infections in Chimpanzees and combined it with the genetical material of SARS-CoV-2 spike protein. The vaccine candidate was based on the idea of teaching the body to recognise the spike protein of the novel coronavirus and prepare the immune system to attack it, in case the virus ever entered the body. Additionally, clinical trials of the vaccine had already begun and more than 320 people were already given the jab of ChAdOx1 nCoV-19.
