Oxford and CanSino Vaccine Prompt a Protective Immune Response in Hundreds of People who Got the Shot

According to Scientists at Oxford University, hundreds of people who got vaccinated for experimental coronavirus vaccine in an early trial prompt a protective immune response. They began testing the vaccine in April in about 1,000 people, where half of them got an experimental vaccine. In a study published on Monday in the journal Lancet, scientists stated that they found their experimental COVID-19 vaccine producing a dual immune response in people aged 18 to 55 that lasted at least two months after they were immunized. Dr. Adrian Hill, director of the Jenner Institute at Oxford University, said that they are seeing an excellent immune response in almost everybody.

Hill also added that neutralizing antibodies are produced and a reaction in the body’s T-cells, which assist in fighting off the coronavirus. Minor side effects such as fever, chills, and muscle pain are experienced during the experimental COVID-19 vaccine. Hill also indicated that in U.K. South Africa and Brazil, there would be more extensive trials assessing the vaccine’s effectiveness, involving about 10,000 people. There will also be another big trial aiming to enroll about 30,000 people in the U.S. soon. Hill confirmed that they might have adequate data by the end of the year to determine if the vaccine should be adopted for mass vaccination campaigns.

Hill also indicated that Oxford’s vaccine is developed to reduce disease and transmission by using a harmless virus — a chimpanzee cold virus, engineered so it can’t spread. In triggering an immune system response, this safe virus carries the coronavirus’ spike protein into the body. Together with drugmaker AstraZeneca, Oxford is committed to making about 2 billion doses to be used globally. He added there was a hope that if they had a vaccine quickly enough, they could put out the pandemic. Hill, however, noted that he thought it was going to be very difficult to control this pandemic without a vaccine.

Germany, France, the Netherlands, Italy, the U.S., and the U.K. are among countries that have signed deals to receive hundreds of millions of doses of the vaccine. According to British politicians, Britons will be the first to get it if the shot proves useful. On Monday, Chinese researchers reported using a similar technique as the Oxford scientists on about 500 people. They said that an immune response was detected in those who were immunized. But they noted that it wasn’t possible to tell if they were protected from the disease since the participants were not exposed to the coronavirus afterward. The Chinese military was approved by China’s government to use CanSino’s vaccine while it explores final-stage studies.
