Off-the-Shelf Vaccine Shows Promise in Preventing Cancer Recurrence

 Researchers have announced encouraging results from an early-stage clinical trial investigating an innovative “off-the-shelf” cancer vaccine designed to prevent the recurrence of pancreatic and colorectal cancers. Unlike personalized cancer vaccines that are tailor-made for each patient—often requiring complex and time-consuming manufacturing—this new approach uses a standardized formulation that can be administered to many patients without genetic customization.





The vaccine, known as ELI-002 2P, specifically targets mutations in the Kras gene, which are present in about 90% of pancreatic cancers and 50% of colorectal cancers. These cancers are notorious for their aggressive nature and high rates of recurrence even after surgery and chemotherapy. The ability to deploy a ready-made vaccine against such a common genetic mutation offers significant advantages in speed, accessibility, and cost.

In the trial, 25 patients who had undergone surgery for pancreatic or colorectal cancer received the vaccine. The study found that patients with the strongest immune responses to ELI-002 2P enjoyed notably longer periods without disease recurrence and had lower mortality rates compared to those with weaker immune responses. Immune activity was measured through T-cell activation and antibody levels, showing the vaccine’s ability to train the body’s immune system to recognize and attack residual cancer cells.

While the results are promising, researchers caution that this was a small study without a control group, so further investigation is needed to validate the findings. However, the potential impact is substantial: a widely available, low-toxicity, and cost-effective cancer vaccine could complement existing treatments and offer hope to patients at high risk of relapse.

The next step will involve larger, randomized clinical trials to confirm efficacy, explore optimal dosing schedules, and evaluate long-term safety. If successful, this approach could represent a paradigm shift in oncology, turning cancer vaccines from niche, individualized treatments into scalable public-health tools.

By harnessing the body’s immune system through a standardized vaccine, researchers aim to create a broadly applicable defense against some of the deadliest and most difficult-to-treat cancers, offering renewed optimism in the ongoing fight against cancer recurrence.

Does AI pose a threat to sustainable development?

Image
  The 2025 World Economic Forum, being held in Davos from Monday to Friday under the theme " Collaboration for the Intelligent Age ", is expected to foster a spirit of cooperation and optimism in the digital age in a more sustainable way, despite the different positions of the participants and global uncertainties. Three experts share their views on the issue with China Daily. Projected estimates indicate that advanced artificial intelligence (AI) systems will necessitate over $1 trillion in investments for cloud and enterprise data center infrastructure within the next five years. The AI infrastructure includes servers equipped with graphics processing units (GPUs) or custom accelerators, dedicated networks, storage solutions and specialized facilities, which are all factors that demand significant capital investment. Therefore, evaluating the scale, potential returns and environmental impact of AI's rapid development and application is essential. The rise of AI will si...

Building urban resilience to climate change

Image
  Building Urban Resilience to Climate Change is an essential framework for cities to safeguard their infrastructure, ecosystems, and populations from the increasing threats of climate change. As urban areas grow and climate impacts intensify, it's crucial to develop adaptive measures that not only reduce vulnerabilities but also promote sustainable urban development. This approach involves a variety of strategies, including enhancing green infrastructure, improving water and energy management, promoting low-carbon transportation, and integrating climate adaptation into urban planning. Urban resilience focuses on creating systems that are both adaptable and responsive to climate stressors like heatwaves, flooding, and storms. By prioritizing nature-based solutions such as urban parks, green roofs, and wetlands, cities can mitigate heat island effects, improve air quality, and protect biodiversity. Moreover, integrating sustainable architecture, resilient infrastructure, and effici...

'Our model of cosmology might be broken': New study reveals the universe is expanding too fast for physics to explain

Image
 A recent study has revealed a puzzling discrepancy in our understanding of the universe’s expansion rate, suggesting that our current cosmological models may need a significant overhaul. The crux of the issue lies in the Hubble constant (H₀), a measure of the universe's expansion rate, which appears to differ depending on how it is calculated. For decades, scientists have relied on two primary methods to determine H₀. The first involves observing the cosmic microwave background (CMB), the faint afterglow of the Big Bang, and extrapolating the universe's expansion rate using early-universe physics. The second method uses the local universe, measuring distances to nearby galaxies via "standard candles" like Cepheid variables and Type Ia supernovae. However, these two methods yield conflicting results. The CMB method, based on data from missions like Planck, estimates H₀ to be around 67.4 kilometers per second per megaparsec (km/s/Mpc) . In contrast, local measurements...
