Personalized mRNA Vaccine Shows Promise Against Late-Stage Kidney Cancer

INIndia|

A recent study published in the journal Nature has reported promising results for a personalized mRNA vaccine designed to treat late-stage kidney cancer, specifically renal cell carcinoma. Conducted by researchers at Dana-Farber Cancer Institute in Boston, the phase one clinical trial involved nine patients with stage III and IV kidney cancer, all of whom remained cancer-free for a median of 40 months following treatment.

The innovative approach involved tailoring vaccines to each patient using genetic material from their tumors. This method identified and utilized neoantigens—mutated protein pieces unique to each tumor—to trigger an immune response against cancerous cells. Notably, the study indicated that seven of the nine patients exhibited significant T cell reactivity against their tumors post-vaccination.

Experts, including Dr. Satya Prakash Yadav of Medanta Hospital, commended the research but cautioned that the vaccine may not be suitable for all cancer types. As the study progresses, the medical community is hopeful about the implications for renal cell carcinoma, although "we should not give false hope," noted Dr. Rajeev Jayadevan, a prominent physician in India.

Human Trafficking Network Busted in Delhi-NCR; Over 30 Children Sold

The Delhi Police have dismantled a human trafficking ring responsible for selling newborns to affluent families in the National Capital Region (NCR). Three suspects were arrested in Dwarka, while the gang's mastermind, identified as Saroj, remains at large, according to police officials. Operating primarily in Gujarat, Rajasthan, and the NCR, the gang reportedly kidnapped children from economically disadvantaged families, with over 30 infants sold for prices ranging from ₹500,000 to ₹1,000,000 (approximately $6,000 to $12,000) each. Among the rescues was a four-day-old newborn. The arrests followed a 20-day investigation where authorities analyzed call records of over 20 suspicious mobile numbers. "The team worked on classified information before apprehending the three suspects on April 8," stated Dwarka Deputy Commissioner of Police Ankit Chauhan. Notably, one of the arrested, Anjali, had previously been arrested in a separate trafficking case. Police are also in the process of identifying and pursuing legal action against families who purchased the children, aiming to hold all parties accountable for their involvement in this illicit trade.
