A vaccine, from the University of Oxford against the coronavirus, has begun to give positive results and produce antibodies and T cells, that can fight coronavirus, the experiment was carried out on 1,077 people. The vaccine, dubbed ChAdOx1 nCoV-19, developed at an unprecedented rate and cannot cause infections in humans, it has been greatly modified to resemble a coronavirus. For this, they used a genetically engineered virus that causes the common cold in chimpanzees. The UK has already ordered 100 million doses of the vaccine. The medical research found that 90% of people developed neutralizing antibodies after a first dose. Only ten people received two doses, and they all developed neutralizing antibodies. Of course, the vaccine has several side effects, with 70% of people in the trial developing a fever or headache. With a low number of cases in the UK, the vaccine study will be moved to other countries, involving 30,000 people in the US, as well as 2,000 in South Africa and 5,000 in Brazil, according to the BBC. The Oxford vaccine is not the first to succeed, other companies, well known as Moderna, were the first of the block, and its vaccine can produce neutralizing antibodies. They inject the coronavirus RNA (its genetic code), which then begins to produce viral proteins to trigger an immune response. BioNtech and Pfizer also had positive results with their RNA vaccine. The medical research cannot show whether vaccines, can either prevent people from getting sick or even reduce their Covid-19 symptoms, since due to the ethical side, impossible to offer people getting sick with coronavirus without a cure. Experts say that a solution could be at the end of this year, but it will take time for a mass launch.
