India well-equipped to swiftly detect, contain new COVID variants: Ex-ICMR DG Bhargava
XFG variant
is part of the SARS-CoV-2 virus's natural evolution, said Prof. (Dr)
Balram Bhargava
, former of Director General of the Indian Council of Medical Research (
ICMR
) and former Secretary of the Department of Health Research.
He added that India is well-positioned to detect and contain emerging variants swiftly due to the widespread deployment of rapid
molecular diagnostic platforms
such as
Truenat
.
As of Tuesday morning, India has reported 6,815 active COVID-19 cases. According to data from the Indian SARS-CoV-2 Genomics Consortium (INSACOG), 163 cases of the new COVID-19 variant XFG have recently been detected across the country.
Dr Bhargava said that XFG variant carries mutations that may enhance its ability to bind to human cells and bypass immune defences.
"Early reports suggest that the variant has high immune escape potential, but there is no current evidence to indicate increased severity.
However, as the virus adapts, India's diagnostic infrastructure has adapted since the very first wave. RT-PCR remains the cornerstone of COVID-19 diagnostics, and the widespread deployment of rapid molecular platforms like Truenat puts India in a strong position to detect and contain emerging variants swiftly--even in remote and resource-limited settings," he said.
Dr Bhargava, who played a key role in India's pandemic response, stressed the continued importance of point-of-care testing in identifying emerging variants such as XFG.
"Vigilance is critical now, and not panic. As we've done in the past, we should continue testing when symptomatic, masking in crowded spaces, and staying up to date with vaccinations," he said.

From The Hindu, July 21, 1975: Second link-up a cliff-hanger
Moscow, July 20: Soviet space scientists spent seven cliff-hanging minutes during the second docking operation between Apollo and Soyuz-19 as the two spacecraft buckled and rolled and even began to rotate, a Soviet space official revealed to-day. Dr. Vladimir Syromyatnikov, the head of the Soviet-American task force which designed and built the docking mechanism used to join the two spacecraft during their flight together through space, said the final link-up had taken place under 'extreme conditions'. The pitching and tossing about of the two spacecraft between 12:33 and 12:40 GMT had been 'rather unexpected', he said. Space controllers watching the action on their television screens lived through seven emotion-filled minutes, he added. He said the fact that all went well in the end was proof of the ability of the mechanism to withstand all the shocks to which it was subjected. 'We do not know the exact reasons for yesterday's incident and specialists from the two countries are at work analysing the causes,' Dr. Syromyatnikov said. The Soviet expert said it would not have been 'tragic' if the mechanism had buckled during the docking operation because the astronauts would have then taken immediate steps to separate the two spacecraft ready for their return to earth. The docking mechanisms were not directly attached to the space capsules used in the descent to earth, Dr. Syromyatnikov noted.

ICMR invites partners to launch and sell its new malaria vaccine
The Indian Council of Medical Research (ICMR) has invited the country's vaccine manufacturers to partner with it to launch and sell a malaria vaccine that its Regional Medical Research Centre, Bhubaneshwar, has developed. Called AdFalciVax, it is a recombinant vaccine, meaning parts of the genes that encode for targets are inserted into a cell, the target proteins are expressed, and then used to trigger an immune response. Malaria is a parasitic infection transmitted by mosquitoes. While the current vaccine protects against the most common one that causes infection in humans called plasmodium falciparum, there are at least four other parasites from the same family known to cause infection in humans. P. vivax is the other one that commonly causes malaria infections, especially in India. The others — p malariae, p ovale, and p knowlesi — cause fewer infections. While the pre-clinical studies have already shown positive indications, the company that collaborates with the ICMR will be responsible for further development, human clinical trials, and scale-up for commercial production. The vaccine contains the genetic material of two targets — one for a major protein called CSP found on the surface of the malaria parasite and another for a combination of parts of two proteins that affect the pathogen's lifecycle. 'There are some key differences in the ICMR vaccine as compared to the other two currently in the market. One, this vaccine used the DNA for the whole CSP protein instead of just a few parts, meaning it is likely to produce a stronger immune response. Two, the other target that is used prevents the development of the p. falciparum in the mosquito's midgut during its lifecycle. What this essentially means is that it prevents the infection not only in the vaccinated person, but stops the further spread of the disease by disrupting the lifecycle of the pathogen even when it has already been picked up by a mosquito from an infected person for further transmission,' said Dr Subhash Singh, project manager for development of the vaccine. Senior scientist Dr Susheel Singh and director Dr Sanghamitra Pati were part of the development process. The pre-clinical validation was done in collaboration with ICMR-National Institute of Medical Research and the National Institute of Immunology.

Shun 'sterlisied living', reconnect with nature to tackle Covid-like pandemics: Renowned scientist
New Delhi: Shunning today's "sterilised" and "hyper-clean" lifestyle and reconnecting with natural elements like soil, rivers, fresh air can strengthen people's immune system and better prepare them to face Covid-like pandemics in future, renowned scientist Ajai Kumar Sonkar has said. In an exclusive conversation with PTI, Sonkar, whose development of pearl-making techniques through state-of-the-art tissue culture surprised the world, used an analogy comparing the human body to a mobile phone. "By coming in touch with nature, the human body gets information about bacteria and their evolving forms just like a mobile phone needs regular software updates to function properly," he said. "Like Covid , any future pandemic will not occur merely due to bacteria and viruses, but because of our own biological mistakes. To deal with such a nightmare, we must reconnect with nature ," said Sonkar, who was awarded Padma Shri , India's fourth-highest civilian award, in 2022. Sonkar, who has conducted in-depth research for years on microbiology and aquatic biology in India and abroad, said, "Modern humans have become so sterilised (artificial and chemical cleanliness shields) that now their bodily immune system is unable to even recognise environmental pathogens." "As long as humans were in contact with soil, rivers, and natural air, their immune system continuously received information about bacteria and their evolving forms (microbial updates), just like how mobile phones receive regular software updates," he added. Sonkar said today's "hyper-clean" culture has distanced the people from this natural protective shield. "We have not only sterilised our homes but have also separated our bodies from the microbes that protect us from diseases," he said. Revealing a particularly startling finding from his research, he said the Ganga River is a living microbial network that reads the microbial data of anyone entering it and responds with protective bacteriophages -- viruses that destroy harmful bacteria. "When people bathe in the river, they introduce their body's microbes to the Ganges, and in return, the Ganges protects them by destroying pathogens through bacteriophages," he said. "This gives natural training to the human body's immune system. This is the reason why people who come in contact with it are more resistant to new diseases," Sonkar, who is considered among the world's leading scientists on microbiome and bacteriophages of the Ganga, said. Sonkar, who has spent decades researching microbiology and aquatic ecosystems in India and abroad, claimed that developed nations like the US and those in Europe were severely affected by Covid due to "microbial amnesia." "Societies like Europe and America have been victims of 'microbial amnesia' for decades. People there live in such clean and sterilised environments that no new 'data' reaches their immune systems. "They are cut off from the changing forms of bacteria/viruses. As a result, whenever a new bacterium arrives, the body takes time to recognise it and the death rate increases," he said. When asked about the way forward, Sonkar said, "We must reconnect with nature. We must see the Ganga not just as a sacred river but as a teacher... Reactivating the biological systems of soil, rivers, and air could be the real strategy to prevent pandemics. "Vaccination is only an insufficient response. In a constantly changing climate environment, vaccination can never replace natural microbial intelligence . Living with the natural ability to fight bacteria and their new forms is the real prevention of any pandemic," he added.
