The #OxfordAstraZeneca COVID-19 vaccine, a version of which is also being used in India, is made from an adenovirus isolated from chimpanzee poop, which has been genetically changed so that it is impossible for it to grow in humans.
AZD1222 was co-invented by the University of Oxford and its spin-out company, Vaccitech.
It uses a replication-deficient chimpanzee viral vector based on a weakened version of a common cold virus (adenovirus) that causes infections in chimpanzees and contains the genetic material of the SARS-CoV-2 virus spike protein.
After vaccination, the surface spike protein is produced, priming the immune system to attack the SARS-CoV-2 virus if it later infects the body.
The vaccine has been granted a conditional marketing authorisation or emergency use in more than 70 countries across six continents.
The Serum Institute of India (@SerumInstIndia), the world's largest vaccine manufacturer by volume, is manufacturing a version of the Oxford-AstraZeneca COVID-19 vaccine named '#Covishield' in India.
@SerumInstIndia Meanwhile, the country registered 1,03,558 new #coronavirus cases in the last 24 hours, the highest ever single-day spike since the onset of the pandemic last year, taking the total tally to 1,25,89,067 on Monday.
@SerumInstIndia So far, 7.91 crore doses of coronavirus vaccine have been administered in the country since the drive began on January 16 after the approval for #Covishield and Bharat Biotech's #Covaxin.
In a world far older than our tame streets lined with fast-food joints, cafes and global supermarkets, a stone-age man stalked his large prey to attack it at the right moment with the most advanced stone tools available to him.
Did you start experiencing scorching summer heat from the very beginning of March 2021? Did you feel this March was much hotter than it usually is? If so, your instincts were spot on.
Last month, the country recorded an average maximum temperature of 32.65°C, which makes March 2021 the third warmest March India has endured in the past 121 years—since record-keeping began!
A new study from the University of Kansas has offered some crucial insight into the mechanisms behind the world's most powerful monsoon systems: Indian summer monsoon or the southwest monsoon.
Earlier this week, on March 29, the daytime temperature in Delhi breached the 40°C-mark—unprecedented for the month of March. If the forecasts hold true, the capital city could very well breach the record heat of 2019 in the upcoming summer months from April to June.
As per the latest seasonal outlook from the India Meteorological Department (IMD), Delhi, along with Haryana and Chandigarh, could witness 0.62°C warmer-than-normal temperatures from April to June.
