Gita Ramjee has become the first Indian-origin South African to have died after contracting the novel coronavirus. Ramjee, a stellar vaccine scientist and an HIV prevention research leader, had returned from London a week ago but reportedly showed no symptoms of COVID-19.
Since the trial participants were not exposed to the coronavirus after vaccination, the scientists said it is not possible for the current study to determine the efficacy of the candidate vaccine.
"The Indian Medical Association has requested all its 3.5 lakh members in 1,800 local branches to voluntarily come out to get vaccinated first to show the world that these vaccines are safe and efficacious," it said.
'However, the importance of children in transmitting the virus remains uncertain,' the scientists cautioned in the study. 'Coronaviruses are a large family of viruses that can cause infection and disease in animals, capable of rapid mutation and recombination, leading to novel viruses that can spread from animals to humans,' they said.
'Better to prevent than to wait for evidence. Protection delayed can also mean protection denied'
Initial data has shown immunity triggered by the two mRNA vaccines -- Pfizer-BioNTech and Moderna -- lasts for at least six months
Delhi, Mumbai and Kolkata have already reached their peak in case numbers in the past seven days, said Manindra Agrawal, a professor at IIT Kanpur and one of the researchers associated with the Sutra Covid model.

Solar Orbiter is on a unique trajectory that will allow its comprehensive set of instruments to provide humanity with the first-ever images of the Sun's poles, the US space agency said. This trajectory includes 22 close approaches to the Sun, bringing the spacecraft within the orbit of Mercury to study the Sun, and its influence on space, it said.
The World Health Organisation has said it is 'not yet clear' whether the newly-detected coronavirus variant Omicron is more transmissible or causes more severe disease compared to other variants, including the highly-transmissible and globally prevalent Delta variant.
In a statement, the PMO said three vaccines are in advanced stages of development in India, out of which two are in Phase II and one is in Phase-III. It further said Indian Scientists and research teams are collaborating and strengthening the research capacities in neighbouring countries such as Afghanistan, Bhutan, Bangladesh, Maldives, Mauritius, Nepal and Sri Lanka.
The researchers from King's College London in the United Kingdom also found that most systemic side effects -- meaning side effects excluding where the injection took place -- peaked within the first 24 hours following vaccination and usually lasted 1-2 days.
'The list of things to be done or added or removed will keep growing and it will be a while before the emerging models settle down into lasting structures,' predicts Umesh Shrikhande, CEO, Taproot Dentsu.
The study noted that nine of 30 large states -- Madhya Pradesh, Bihar and Telangana, Jharkhand, Uttar Pradesh, Maharashtra, West Bengal, Odisha, and Gujarat -- have high vulnerability to be impacted by the COVID-19 pandemic.
The United States intelligence community has failed to reach any firm conclusion on the exact origin of COVID-19 and is split on whether it leaked from a lab in China or emerged in nature, even though it does not believe the virus was developed as a biological weapon, according to results of a detailed review ordered by President Joe Biden.
Based on the observations, scientists said that additional care may be required for older men or those with underlying conditions. Yang and his team analysed several patient datasets to see if there were differences in how men and women respond to COVID-19.
As the Omicron strain spreads across the globe and questions on vaccine inequity dominate discussions, scientists are still scrambling to learn more about emerging variants of the deadly virus that has claimed millions of lives and crippled economies.
Omicron can evade the immune protection conferred by COVID-19 vaccines and natural infection, according to a peer-reviewed study which also suggests that the new variant of coronavirus is completely resistant to antibody therapies in use today.
However, the probe agencies stressed that all angles were being covered in the probe.
According to the study, published in JAMA Pediatrics, children are more likely to get very sick if they have other chronic conditions like obesity. "It is also important to note that children without chronic illness are also at risk. Parents need to continue to take the virus seriously," said coauthor of the study.
Long queues were seen outside walk-in vaccination centres across the UK on Monday as people queued for their booster vaccine doses, even as the government's work from home guidance came in force as part of measures to tackle the "tidal wave" of the Omicron variant of COVID-19.
"In addition to spreading more quickly, it also now appears that there is some evidence that the new variant - the variant that was first identified in London and the south east (of England) -- may be associated with a higher degree of mortality," Johnson said on Friday in his address at a virtual briefing from 10 Downing Street.
As the Omicron variant of Sars-CoV-2 takes centrestage, vaccine makers in India are of the view that scaling up the existing vaccines to make them more effective is possible.
Online marketplace majors, e-grocers, Internet of Things firms, app-based companies and transport service aggregators are among those that have had to shut shop or scale down operations. Now, survival skills like upskilling and retraining will determine who makes it.
ICMR's serological survey, whose findings will be made public next week, suggests that the rate of contagion may be a lot higher in most-affected cities such as Delhi, Mumbai, and Pune.
The approval by the Drugs Controller General of India (DCGI) was given on the basis of recommendations submitted by a COVID-19 subject expert committee (SEC) of the Central Drugs Standard Control Organisation (CDSCO).
India achieved a major milestone in its vaccination programme against COVID-19 as the cumulative vaccine doses administered in the country surpassed the 200-crore mark on Sunday.
Melting of Himalayan glaciers has doubled since the start of the 21st century due to rising temperatures, losing over a vertical foot and half of ice each year and potentially threatening water supply for hundreds of millions of people in countries, including India, according to a study published in 2019.

Italy, previously Europe's worst-hit, has recorded 33,600 COVID-19 deaths.
'Above 2,000 metres the gradient of the Himalayas is very steep and if you build any infrastructure (roads, dams, hydro power projects) in these regions, it will not be able to sustain these events (the onslaught of debris that comes down with great speeds).'
On both the occasions, the missiles intercepted the simulated targets with pinpoint accuracy. The missiles were tested for minimum and maximum range.
