    What is the Cancer Vaccine Russia is offering?

    Why in the News?

    In December 2024, Russia announced the development of a new mRNA-based personalized cancer vaccine, with plans to make it available for free to patients by early 2025.

    What is mRNA (Messenger RNA)?

    • mRNA is a type of RNA that transports genetic information from DNA to ribosomes, guiding the production of proteins.
    • It tells the cell which proteins to make by providing the exact sequence of amino acids.
    • Unlike DNA, mRNA does not stay in the cell permanently; it gets degraded after protein synthesis.
    • mRNA-based vaccines (like COVID-19 vaccines) teach cells to produce harmless viral proteins, triggering an immune response.

    What is an mRNA Cancer Vaccine?

    • Unlike traditional vaccines, mRNA vaccines provide genetic instructions to train the immune system to detect and attack cancer cells.
    • This technology gained prominence with the COVID-19 vaccines (Pfizer-BioNTech, Moderna) and is now being adapted for cancer treatment.
    • These vaccines are therapeutic, designed for patients who already have cancer, not for prevention.

    How do mRNA Cancer Vaccines Work?

    • Cancer cells evade the immune system by suppressing immune responses.
      • Immunotherapy works by enhancing the body’s natural ability to detect and destroy these cancerous cells.
    • Unlike chemotherapy, which kills both healthy and cancerous cells, immunotherapy selectively targets only cancer cells, reducing harmful side effects.
    • mRNA cancer vaccines are customized for each patient, targeting specific tumor antigens, making them highly personalized and potentially more effective.
    • While traditional infectious disease vaccines prevent illness, mRNA cancer vaccines are therapeutic, meaning they are administered to patients who already have cancer to help their immune system fight the disease.

  • Foreign Policy Watch: India-China

    [15th February 2025] The Hindu Op-ed: Dealing with China’s weaponisation of e-supply chains

    PYQ Relevance:

    Q) The USA is facing an existential threat in the form of China, that is much more challenging than the erstwhile Soviet Union.” Explain.  (UPSC CSE 2021)

     

    Mentor’s Comment: UPSC mains have always focused on China as a threat to the USA (2021), and China is using its economic relations and positive trade surplus as tools (2017).

    In mid-January, reports said China blocked its engineers and technicians from working at Foxconn in India and recalled those already there. It also restricted exports of key manufacturing equipment, which China dominates. While Foxconn brought in Taiwanese workers, the lack of equipment is a bigger challenge. This move threatens India’s goal of becoming a global manufacturing hub.

    Today’s editorial discusses challenges arising from China’s dominance in the global supply chain. This topic is relevant for GS Paper 2 and GS Paper 3 in the UPSC Mains.

    _

    Let’s learn!

    Why in the News?

    Recently, China has stopped its engineers and technicians from travelling to work at Foxconn’s facilities in India.

    How is China using e-supply chains as a strategic tool?

    • Monopoly Over Critical Manufacturing Equipment: China dominates the production of high-tech manufacturing equipment required for semiconductor and electronics production. Example: In early 2024, China restricted the export of specialized manufacturing machinery to Foxconn in India, slowing down iPhone assembly and production.
    • Control Over Key Raw Materials: China holds a significant share of the global supply of rare earth elements (REEs) essential for electronics, EV batteries, and defense technology. Example: In 2023, China imposed export restrictions on gallium and germanium, two critical metals used in semiconductor and military applications, impacting global supply chains.
    • Workforce and Knowledge Transfer Restrictions: By preventing its engineers and skilled technicians from working in foreign manufacturing hubs, China restricts the transfer of tacit knowledge to competitors. Example: Chinese engineers working at Foxconn’s Indian facilities were recalled, creating a skills gap that affected Apple’s production capacity.
    • Disrupting Supply Chains to Gain Geopolitical Leverage: China can manipulate logistics, trade policies, and export restrictions to pressure countries and corporations dependent on its supply chains. Example: During the U.S.-China trade war, China imposed export controls on key components for companies like Huawei and Apple, demonstrating its leverage in global electronics production.
    • Deep Integration into Global Manufacturing Networks: Through initiatives like the Belt and Road Initiative (BRI) and heavy investments in industrial zones, China ensures that multinational corporations remain reliant on its supply chains. Example: Despite U.S. sanctions, companies like Tesla and Apple continue significant operations in China due to its well-integrated and cost-effective supply chain ecosystem.

    What are the risks and vulnerabilities posed by China’s control over e-supply chains?

    • Disruptions to Critical Industries: China’s dominance in semiconductor manufacturing, rare earth metals, and electronics components makes other nations vulnerable to supply chain shocks.
      • India depends on China for over 75% of electronic components, affecting smartphone and telecom industries. The 2020 global chip shortage, worsened by China’s export controls, severely impacted industries like automobiles, defence, and consumer electronics.
    • Geopolitical and Economic Coercion: China can weaponize supply chains to exert diplomatic pressure or punish countries for political disagreements.
      • Post-Galwan clash (2020), India faced delays in customs clearance for Chinese goods, disrupting industries reliant on imports.
      • Lithuania faced trade restrictions in 2021 after allowing a Taiwan representative office, showing how China uses supply chains as leverage.
    • Vulnerability in Strategic Sectors (Telecom, Defense, Energy): Dependence on Chinese technology in strategic sectors poses risks related to cybersecurity, espionage, and sabotage.
      • India banned Huawei and ZTE from 5G trials due to concerns over data security. The U.S. and EU have imposed restrictions on Chinese telecom firms citing national security threats.
    • Supply Chain Manipulation and Price Volatility: China’s control over rare earth metals, batteries, and semiconductors allows it to manipulate prices and supply.
      • Despite efforts to develop local lithium-ion battery production, India still relies on China for key materials, affecting the EV sector. In 2023, China restricted gallium and germanium exports, leading to price spikes for these critical semiconductor materials.
    • Stifling Competitor Growth and Technological Dependence: China restricts the transfer of critical machinery and skilled labor to competitors to maintain its manufacturing edge.
      • China’s ban on engineers working in Indian Foxconn plants and export curbs on key equipment have slowed India’s smartphone manufacturing expansion. U.S. firms like Apple, Tesla, and Intel remain dependent on China’s supply chains, despite attempts at diversification.

    How can countries and companies safeguard themselves from China’s influence over e-supply chains? (Way Forward)

    • Supply Chain Diversification (China Plus One Strategy): Countries and companies should expand production to alternative locations to reduce reliance on China.
      • Example: Apple is shifting iPhone production to India, Vietnam, and Mexico to mitigate risks from China. The U.S. has passed the CHIPS Act (2022) to boost domestic semiconductor manufacturing and reduce reliance on Chinese supply chains.
    •  Strengthening Domestic Manufacturing and R&D: Governments should invest in local industries, incentivize component manufacturing, and build advanced R&D ecosystems.
      • Example: India’s Production-Linked Incentive (PLI) Scheme supports domestic electronics and semiconductor manufacturing. Japan and South Korea are increasing investments in semiconductor fabs to reduce dependence on China.
    •  Forming Strategic Trade Alliances and Technology Partnerships: Nations should collaborate on trade agreements and secure alternative sources for critical materials and technology.
      • Example: India, the U.S., Japan, and Taiwan are working together under the Chip 4 Alliance to strengthen the semiconductor supply chain. The EU-U.S. Trade and Technology Council (TTC) is securing alternative semiconductor and rare earth suppliers.
  • Panchayati Raj Institutions: Issues and Challenges

    Panchayat Devolution Index report released

    Why in the News?

    The Ministry of Panchayati Raj released a report in Delhi on Thursday about how powers are given to Panchayats in different states. The report ranks states and UTs based on six key areas.

    What are the Key Highlights of the Report?

    • Devolution Index: The report ranks states and Union Territories (UTs) based on six dimensions: Framework, Functions, Finances, Functionaries, Capacity Enhancement, and Accountability.
      • The overall devolution has increased from 39.9% to 43.9% between 2013-14 and 2021-22.
    • Top Performing States: The top five states in the devolution ranking are Karnataka, Kerala, Tamil Nadu, Maharashtra, and Uttar Pradesh. Notably, Uttar Pradesh improved its rank significantly due to enhanced accountability measures.
      • Uttar Pradesh made a significant jump from 15th to 5th place, highlighting governance reforms and accountability measures.
    • Capacity Building & Infrastructure Growth: The Rashtriya Gram Swaraj Abhiyan (RGSA) played a crucial role in increasing the capacity enhancement index from 44% to 54.6%, along with improved Panchayat infrastructure (office buildings, internet connectivity, etc.).
    • Significant Progress in Functionaries: The percentage of functionaries assigned to Panchayats increased from 39.6% to 50.9%, indicating efforts in recruitment and personnel strengthening.

    What are the Major concerns in effective Devolution?

    • Election Management: State Election Commissions (SECs) sometimes consult with state governments on election dates, leading to potential delays or political manipulation.
      • Example: In Maharashtra, Panchayat elections were delayed in 2022 due to the state government’s interference
    • Non-centrality of Panchayats: Panchayats operate in subjects designated for them in the eleventh schedule but face challenges that undermine their constitutional mandate.
      • Example: In many states, rural development schemes like PMGSY (Pradhan Mantri Gram Sadak Yojana) are implemented by state departments rather than Gram Panchayats.
    • Inadequate devolution of functions, funds, and functionaries: The devolution of functions, funds, and functionaries to PRIs has been inadequate, limiting their ability to effectively discharge their responsibilities.
      • Example: In Jharkhand and Odisha, despite having legal provisions for devolution, Panchayats have limited control over education, health, and agriculture schemes.
    • Lack of financial autonomy: PRIs don’t have enough financial independence since they mostly depend on irregular and inadequate grants from state governments.
      • Example: In Uttar Pradesh, Gram Panchayats rely heavily on state grants for executing local projects.
    • Lack of Support Staff: There is a severe lack of support staff and personnel in panchayats, such as secretaries, junior engineers, computer operators, and data entry operators, which affects their functioning and delivery of services by them.
      • Example: In Bihar, several Gram Panchayats function with just one Panchayat Secretary managing multiple villages.

    What are the recommendations in the report? 

    • Comprehensive Curriculum Development: Implementing a two-year course in Local Public Service Management that covers essential areas such as public systems, financial management, personnel management, law, and e-governance for Panchayat functionaries
    • Enhance Capacity Building & Digital Governance: Improve digital infrastructure, training programs, and data-driven governance. Example: Telangana’s success in capacity enhancement highlights the importance of institutional strengthening for effective governance.
    • Ensure Greater Transparency & Accountability: Implement real-time financial monitoring, social audits, and grievance redressal systems. Example: Uttar Pradesh’s leap in rankings is attributed to anti-corruption measures and a robust transparency framework.

    Way forward: 

    • Strengthening Institutional Autonomy & Devolution: Ensure full devolution of functions, funds, and functionaries to Panchayati Raj Institutions (PRIs) with legal safeguards to prevent state interference. Example: Karnataka’s success in decentralized governance through direct fund transfers to Gram Panchayats.
    • Capacity Building & Technology Integration: Expand digital infrastructure, conduct regular training for PRI members, and adopt real-time monitoring for transparency. Example: Telangana’s effective use of digital governance and capacity-building initiatives under the Rashtriya Gram Swaraj Abhiyan (RGSA).
