Why Oxford Vaccine Results Boost India’s Fight Against Covid | India News
“The efficacy and safety of this vaccine confirm that it will be very effective against Covid-19 and will have an immediate impact on this public health emergency,” Pascal Soriot, Astra’s CEO, said in a statement.
The vaccine developed by the University of Oxford was 90% effective in preventing Covid-19 when administered as a half dose followed by a full dose at least a month apart, according to data from late-stage trials in Gran Britain and Brazil.
Another dosage regimen showed an efficacy of 62% when administered as two full doses separated by at least one month, and the combined analysis of both dosage regimens resulted in a mean efficacy of 70%.

The encouraging results are expected to come as an injection in the arm for India, as it has the inexpensive Oxford vaccine to inoculate most of its population.
The Oxford candidate is being manufactured locally by the Serum Institute of India, which aims to deliver the first of 100 million doses to healthcare workers and the elderly by January next year.
In reaction to the announcement, Serum CEO Adar Poonawalla said he’s delighted to learn that Covishield, the local name for the vaccine, will soon be widely available.
“I am pleased to hear that Covishield, a low-cost, logistically manageable and soon to be widely available vaccine, the # COVID19 vaccine, will offer protection up to 90% in one type of dosing regimen and 62% in the other regimen. dosage. More details on this will be provided tonight, “Poonawalla said on Twitter.
The vaccine has a significant advantage over candidates like Moderna and Pfizer, which were also found to be more than 90% effective, in terms of cost and storage.
Poonawalla recently said that the vaccine will have a maximum price of Rs 1,000, which is only a fraction of the expected price of Moderna and Pfizer vaccines.
In addition, the puncture can be kept at refrigerator temperatures, while those from Pfizer and Moderna, based on novel messenger RNA technology, require freezing for longer-term storage and transport.
The Oxford University vaccine is based on a harmless, weakened version of a common cold virus, or adenovirus, that causes infections in chimpanzees. The vector (the carrier) is derived from adenovirus (ChAdOx1) extracted from chimpanzees. It is genetically engineered so that it does not reproduce in humans.
