The leading contender for vaccine OXFORD-ASTRAZENECA could release the results of the trials conducted in India by November-end of early-December. In case that happens, the Oxford vaccine manufactured by Serum Institute would be available sooner than expected. Niti Aayog member Dr VK Paul said that the vaccine candidates are progressing well in clinical trials. After the Oxford-AstraZeneca vaccine trial, Johnson and Johnson had to halt their vaccine trial after a participant fell in. However, as for all the trials being carried out in India, there has been no reports of any participant falling sick. Meanwhile, another company in India has joined the race to develop a COVID-19 vaccine. It must also be kept in mind that the number of doses is a key factor in vaccination. The fewer the number of doses, the faster the inoculation process would wrap up. India so far has only two-dose and three-dose vaccines. Oxford vaccine and Bharat Biotech’s candidate are two-dose vaccines, while Zydus Cadila’s is three-dose.
