What is Oxford university’s ChAdOx1 Covid-19 vaccine?

The AZD1222 vaccine developed by Oxford is based on a chimpanzee adenovirus called ChAdOx1, responsible for causing common cold in Chimpanzee. However, the virus is modified further to make sure it doesn’t infect the humans. The genetic instructions of the coronavirus were transferred by spike protein to make sure the vaccine resembles the coronavirus. The trials have already been conducted on monkeys with no adverse effects recognized so far.

The next phases of Oxford vaccine will see if the immune response at the early stages protects against the virus or not. “The global programme is made up of a Phase III trial in the US enrolling 30,000 patients, a paediatric study, as well as Phase III trials in low-to-middle income countries including Brazil and South Africa which are already underway,” the university said in a release. It is still unknown how strong immune response is required to completely protect against the disease. There is still much work left before we declare a vaccine that can fight against the pandemic.

Till date, the world has seen more than 6 lakh deaths due to COVID-19 with more than 14 million confirmed cases. India stands at the third position in the most number of cases reported while the United States of America has reported the highest number of cases. With the cases increasing at a rapid pace, there is an urgent need for the Vaccine to protect the people.
