New Delhi, July 21 : The Serum Institute of India (SII) will launch the first Covid-19 vaccine called 'Covishield' and commence its trials soon in India. SII released a representative image of the vial of Covishield which is the vaccine developed by the Oxford University and pharma giant, AstraZeneca. Adar Poonawalla, CEO, SII, in a tweet, said: "Congratulations to the teams at @UniofOxford and @AstraZeneca for getting this product data out. It all seems to be going well. Hope to get positive results in the phase three trials in a few months. We have also hope to start phase three trials in India soon". The SII will be applying soon for the licensure trials of AstraZeneca Oxford vaccine to the Indian regulator. Commenting on the AstraZeneca-Oxford Vvaccine's results, Poonawalla said: "The trials have shown promising results and we are extremely happy about it. We will be applying for the licensure trials to the Indian regulator in a week's time. As soon as they grant us permission, we will begin with the trials for the vaccine in India. In addition, we will soon start manufacturing the vaccine in large volumes." Monday marked an important day in the battle against Covid as the first results of Oxford's Covid-19 vaccine show it is safe and provokes an immune reaction in a person that lasts for almost two months. The researchers are indicating that the vaccine may be ready by year-end. The results showed that more than 91 per cent of volunteers injected produced an immune response against the coronavirus that lasted a month or more. The immune responses remained strong for at least 56 days. Oxford University's vaccine - called AZD1222 - is being manufactured by pharmaceutical major AstraZeneca and the UK Government has ordered 100 million doses ahead of time. As per the results, the vaccine boosted T cell and antibody immunity. The vaccine produced a strong responses on both accounts, the study found, with T cell immunity peaking after two weeks and then dropping slightly by day 56. Antibody immunity, on the other hand, peaked after four weeks and remained high by day 56, indicating that it may well last for even longer. /IANS
