A. Melanoma cells come from melanocytes, the skin cells that give it color. When these cells grow too much and become cancerous, they cause melanoma, a dangerous kind of skin cancer that can spread fast if not treated early.
Q. What is mRNA, and how is it used in vaccines?
A. mRNA, or messenger RNA, is a molecule that carries genetic instructions from DNA to the cell's protein-making machinery. It acts like a messenger, conveying the code needed to build specific proteins that perform various functions in the body. In vaccines, mRNA teaches cells to produce a harmless piece of a virus or cancer antigen, triggering the immune system to respond and protect the body.

This novel
cancer vaccine
is designed to train the immune system to recognize and attack melanoma cells by creating a bespoke mRNA blueprint derived from each patient's unique tumor mutations. The process involves sophisticated artificial intelligence algorithms that analyze the tumor's genetic data to produce a molecular template, which is then synthesized at Gamaleya's production facilities. This tailor-made mRNA encodes proteins that activate a targeted cytotoxic immune response, aiming not only to eradicate primary tumors but also to address metastatic cancer sites.
Gintsburg elaborated that the entire vaccine development cycle—from tumor sequencing to vaccine production—can be completed within about one week due to AI-assisted mathematical modeling and neural network computing. This rapid manufacture represents a significant leap compared to typical timelines in personalized cancer therapies.
Q. What is a personalized cancer vaccine?
A. Personalized cancer vaccine is a tailored immunotherapy designed to train the patient's immune system to recognize and attack their specific cancer cells. It uses information from the patient's tumor genetics to create a unique vaccine that targets tumor-specific mutations, differing from general vaccines.
The vaccine model was developed starting in mid-2022 and has already demonstrated promising efficacy in preclinical animal studies, showing the ability to suppress tumor growth and reduce metastasis.
The upcoming Phase I clinical trials will take place at two of Russia's foremost oncology centers: the
Hertsen Research Institute
and the N.N. Blokhin National Medical Research Center of Oncology in Moscow. Importantly, this tailored vaccine is part of a wider Russian initiative to advance cancer treatment across various difficult-to-treat types, including pancreatic, kidney, and non-small-cell lung cancers.
The Russian Ministry of Health classifies this vaccine development and approval under a new, specialized regulatory process recognizing its individualized nature, differing fundamentally from traditional drug registration. The state plans to provide this cancer vaccine free of charge to Russian citizens, with an estimated production cost of around 300,000 rubles (approx. USD 2,869) per dose covered by government funding.
According to health authorities, about 4 million Russians live with cancer, and approximately 625,000 new cancer cases are diagnosed annually, underlining the urgent need for innovative therapies. The vaccine's success could mark a pivotal moment in Russia's fight against cancer and elevate its personalized medicine program.
Unlike the COVID-19 mRNA vaccines designed to target a single viral antigen, this personalized cancer vaccine encodes multiple neoantigens specific to each patient's tumor, offering a multi-targeted immune approach.

Model school plans tours, steps to de-stress students
Trichy: Stunned by two student suicides in two months, govt model school authorities in Trichy are planning to undertake a series of stress management measures like recreational trips and counselling for students. Most of the students reside in the hostel to prepare for competitive exams along with their regular classes. Officials said initially 55 Class XII students, who are also CLAT (Common law admission test) aspirants, will be taken on a day's trip to Thanjavur next week. "Both the students who died by suicide recently were CLAT aspirants. For now, this group has complained more of stress. However, we will gradually identify students in other streams and proceed accordingly," an official source told TOI. A targeted approach would be adopted to prevent further such incidents. The school currently has about 520 students also getting coached across various streams of competitive exams. The administration plans to rope in speakers and personalities to engage with students on life and stress management, organize visits by a govt psychiatrist and mental health team every 15 days, and conduct regular parent-teacher meetings. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Why Seniors Are Snapping Up This TV Box, We Explain!

"To blame the school administration or the nature of coaching as a reason for stress is unfair," said the official. On Thursday, Class XII student B Yuvraj from Vellore had hanged himself in his hostel room. Minister Anbil Mahesh Poyyamozhi had paid a visit to the school on Friday and advised more care. In June, a girl named D Krithiga from Thiruvallur also died by suicide in her hostel room. The school with state-of-the-art infrastructure was built at a cost of Rs57 crore to exclusively train students for clearing competitive exams. It was inaugurated by chief minister M K Stalin on May 8. Suicides in other govt schools have also been recorded this year. A class XII student was also found hanging in the hostel of the blind school in Puthur in March.

Aarogyasri overhaul: 3 crore beneficiaries, coverage raised to Rs 10L
1 2 Hyderabad: In a major push to make healthcare more inclusive and accessible, the Telangana govt has significantly expanded the Aarogyasri scheme, both in terms of coverage and benefits. With fresh ration card distributions and long-pending hospital payments cleared, the health initiative is set to cover over three crore people. At the heart of this transformation is the automatic linkage of white ration cards to Aarogyasri eligibility. As more families receive these cards, they are instantly enrolled under the scheme, leading to a dramatic rise in beneficiaries. According to state officials, an additional 30 lakh people have been brought under the scheme's ambit in recent months, taking the total to over 93 lakh families. Arrears cleared You Can Also Check: Hyderabad AQI | Weather in Hyderabad | Bank Holidays in Hyderabad | Public Holidays in Hyderabad A key turning point was the govt's decision to clear ₹1,590 crore in arrears owed to private hospitals. This move, completed over the past 20 months, has restored confidence among private healthcare providers, many of whom had previously reduced their participation due to delayed payments. With this financial clarity, more hospitals are coming forward to rejoin the network. Over 100 private hospitals have expressed interest in being empanelled under Aarogyasri, boosting the scheme's capacity across the state. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Buy Resmed AirSense 11 with flat 20% off ResMed Buy Now Undo Enhanced treatment cap The govt has also made critical upgrades to the benefits offered. The treatment cap has been increased from previous limits to ₹5 lakh–₹10 lakh, enabling coverage for high-cost treatments that were earlier inaccessible to many low-income families. In a first-of-its-kind review in a decade, health minister Damodar Raja Narasimha met with hospital administrators and revised treatment package rates by 22%, acknowledging rising costs and aiming to ensure better quality of care under the scheme. Broader reach Originally designed to cover 90 lakh white ration cards (supporting 28.4 million individuals), the scheme's expansion now supports over three crore people, thanks to the ongoing white ration card distribution drive. The integration process has become more seamless and transparent, eliminating bureaucratic hurdles for families seeking medical help, officials siad. Officials also report increased utilisation of Aarogyasri for chronic illnesses such as kidney diseases, thanks to the scheme's now broader and better-funded structure. The renewed Aarogyasri scheme, with deeper coverage, higher financial support, and better hospital participation, is emerging as a cornerstone of the state's public health infrastructure, officials added.

PGI's Rs 490 cr Advanced Neuroscience Centre nears launch by Sept
Chandigarh: India's healthcare system, currently facing a critical shortage of neurologists—with just one specialist available per million people—is on the brink of a major breakthrough. The Postgraduate Institute of Medical Education and Research (PGI), Chandigarh, is preparing to launch its long-awaited Advanced Neuroscience Centre, a Rs 490 crore project that promises to revolutionise neurological and neurosurgical care across the country. Approved in 2017 and with construction beginning in 2020, the centre is now nearing full operationalisation. PGI officials have confirmed that the outpatient department (OPD) is expected to become functional by September, marking a significant milestone in the journey to improve access to specialised brain and spine treatment. Once fully operational, the centre will join the ranks of premier institutions like NIMHANS Bengaluru and AIIMS Delhi's Cardiothoracic and Neurosciences Centre. However, PGI's facility stands out for its integrated model, combining neurology and neurosurgery services under one roof. "This will be the largest such centre in India where both specialities are housed in a single building," said a PGI official. "Beds will be consolidated, not scattered across departments, ensuring seamless care for patients. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Access all TV channels anywhere, anytime Techno Mag Learn More Undo " The project has faced several hurdles over the years. Construction was halted during the Covid pandemic in March, 2020 and resumed with limited labour by June. More recently, delays were caused by the renewal of pollution control clearance from the state pollution control board and the calculation of property tax arrears owed by PGI. Despite these challenges, the administration remains optimistic about the centre's phased rollout. The facility will feature 300 general ward beds, 10 modular operating theatres, dedicated ICUs, 10 High Dependency Unit (HDU) beds, and 30 private ward beds. It will offer advanced sub-specialities such as cerebrovascular surgery, skull base surgery, and spinal functional neurosurgery. A key highlight is the Brain Suite, a specialised operating room designed for complex neurosurgical procedures. While some equipment requests—like a 3T MRI, Bi-plane DSA, and dual-energy CT scan—were scaled down due to budget constraints, PGI faculty believe the centre will still significantly enhance diagnostic and treatment capabilities. "Patients come from all corners of India because of the expertise and affordability PGI offers," said a senior faculty member. The Advanced Neuroscience Centre is expected to serve as a national hub for neurological care, addressing a long-standing gap in specialised treatment. With its integrated approach and cutting-edge infrastructure, the centre is poised to offer a lifeline to thousands of patients who currently struggle to access timely and affordable brain and spine care.
