Essential Programme on Immunization

The year 2024 commemorates 50 years since the launch of the Expanded Programme on Immunization (EPI) by the World Health Organization (WHO) in 1974 which is now known as Essential Programme on Immunization.

About Essential Programme on Immunization:

  • It was launched as the Expanded Programme on Immunization (EPI) by World Health Organisation in 1974 to ensure that all children, in all countries, benefited from life-saving vaccines.
  • It has evolved into what is now commonly known as the Essential Programme on Immunization.
  • Disease covered (Total 13):
    • Initially this programme focused on protection against six childhood vaccine-preventable diseases namely Bacillus Calmette-Guérin (BCG), diphtheria, pertussis, tetanus, polio, and measles.
    • Later on WHO added 7 more disease under this initiative Haemophilus influenzae type B (Hib), Hepatitis B (HepB), rubella, pneumococcal disease (PNC), rotavirus (Rota), human papillomavirus (HPV) and COVID-19 (for adults).

India’s Universal Immunization Programme (UIP)

  • India launched the EPI in 1978, which was later renamed as the Universal Immunization Programme (UIP) in 1985. 
  • Objectives:
    • To rapidly increase immunization coverage.
    • To improve the quality of services.
    • To establish a reliable cold chain system to the health facility level.
    • Monitoring of performance.
    • To achieve self-sufficiency in vaccine production.
  • Eligibility:
    • All beneficiaries’ namely pregnant women and children can get themselves vaccinated at the nearest Government/Private health facility or at an immunization session site (Anganwadi centres/ other identified sites) near to their village/urban locality on fixed days.
    • The UIP covers all sections of the society across the country with the same high quality vaccines.
  • Under UIP, immunization is providing free of cost against 12 vaccine preventable diseases.
  • Nationally against 9 diseases – Diphtheria, Pertussis, Tetanus, Polio, Measles, Rubella, severe form of Childhood Tuberculosis, Hepatitis B and Meningitis & Pneumonia caused by Hemophilus Influenza type B.
  • Sub-nationally against 3 diseases – Rotavirus diarrhoea, Pneumococcal Pneumonia and Japanese Encephalitis; of which Rotavirus vaccine and Pneumococcal Conjugate vaccine are in process of expansion while JE vaccine is provided only in endemic districts.

Thrombosis with Thrombocytopenia Syndrome

Recently, AstraZeneca (AZ) has admitted its Covid vaccine may cause Thrombosis with Thrombocytopenia Syndrome (TTS).

About Thrombosis with Thrombocytopenia Syndrome:

  • It is characterized by blood clots (thrombosis) combined with low levels of platelets (thrombocytopenia), which are necessary for blood clotting.
  • It often involves unusual blood clot locations, such as in the brain (cerebral venous sinus thrombosis) or abdomen.
  • Symptoms of TTS: Severe or persistent headaches, blurred vision, Shortness of breath, Chest pain, Leg swelling, Persistent abdominal pain and Easy bruising or tiny blood spots under the skin beyond the injection site etc.
  • It is classified into two tiers based on the location of the blood clot and the severity of the symptoms.
  • Tier 1:
    • Uncommon site of thrombosis (like the brain-cerebral venous sinus thrombosis or the gut such as splanchnic vein, associated with bowel ischaemia and surgery, portal vein or other rare venous and arterial thromboses).
    • Thrombosis in more common locations (deep vein thrombosis or pulmonary embolism).
    • Platelet count is less than 1,50,000 per microlitre.
    • A positive anti-PF4 ELISA result is supportive, but not required for diagnosis.
  • Tier 2:
    • Common sites of thrombosis include leg or lungs (venous thromboembolism, deep vein thrombosis, pulmonary embolism).
    • Platelet count is less than 1,50,000 per microlitre.
    • A positive anti-PF4 ELISA result is required.
  • Tier 1 TTS carries a higher risk of mortality and morbidity than Tier 2. Tier 1 could be more common among younger age groups.

DRDO’s Supersonic Missile-Assisted Torpedo Delivery System Achieves Success

The Defence Research and Development Organisation (DRDO) has achieved a significant milestone in enhancing India’s anti-submarine warfare capabilities with the successful flight-test of the Supersonic Missile-Assisted Release of Torpedo (SMART) system. This next-generation torpedo delivery system was successfully flight-tested on May 01, 2024, at around 8:30 AM from Dr. APJ Abdul Kalam Island off the coast of Odisha.

Extending the Range of Lightweight Torpedoes

  • SMART is a missile-based system designed to significantly extend the range of lightweight torpedoes used by the Indian Navy. By incorporating advanced technologies, this canister-based system can deliver torpedoes far beyond their conventional range, providing a strategic advantage in anti-submarine warfare operations.

Advanced Sub-Systems and Mechanisms

The SMART system comprises several cutting-edge sub-systems, including:

  • Two-stage solid propulsion system
  • Electromechanical actuator system
  • Precision inertial navigation system

Additionally, the system incorporates advanced mechanisms such as symmetric separation, ejection, and velocity control, which were successfully validated during the flight-test.

Enhancing Naval Capabilities

  • Defence Minister Shri Rajnath Singh congratulated the DRDO and industry partners on the successful flight-test, stating, “The development of the system will further enhance the strength of our Navy.”
  • Dr. Samir V Kamat, Secretary, Department of Defence R&D and Chairman DRDO, lauded the synergistic efforts of the entire SMART team and encouraged them to continue on the path of excellence.

Revolutionary System for Naval Warfare

  • With its advanced capabilities, the SMART system represents a significant advancement in India’s naval warfare capabilities. By extending the range of lightweight torpedoes, this system will provide the Indian Navy with a strategic advantage in safeguarding the nation’s maritime interests.

Zimbabwe Introduces New Currency Amid Skepticism

Zimbabwe has launched a new currency called the ZiG (short for Zimbabwe Gold) in an attempt to address the country’s long-running currency crisis. The ZiG, backed by Zimbabwe’s gold reserves, was introduced electronically in early April and has now been released in banknote and coin form.

Mistrust and Rejection

  • Despite being the sixth currency since the collapse of the Zimbabwe dollar in 2009, the ZiG is already facing mistrust and rejection from some quarters. Several government departments and businesses are refusing to accept the new currency, preferring to stick with the U.S. dollar, which remains the most trusted currency among Zimbabweans.

Conflicting Policies

  • While some businesses, like gas stations, have been allowed to reject the ZiG in favor of U.S. dollars, others are being ordered to use the new currency exclusively, facing punishment if they don’t comply. This conflicting approach has raised suspicions about the government’s commitment to the ZiG.

A Painful History

  • Zimbabwe’s hyperinflation crisis in 2009, which saw prices spiraling out of control and the printing of a 100 trillion Zimbabwe dollar banknote, remains a painful memory for many Zimbabweans. The U.S. dollar became a lifeline during this period, and its use has continued despite subsequent currency attempts.

  • The Bharat 6G Alliance and Industry Alliance 6G are poised to sign an agreement soon, with plans to finalize collaboration details in the coming quarter.

Memorandum of Understanding (MoU) Expected

  • Similar to the agreement with the US, the partnership between Bharat 6G and Industry Alliance 6G is likely to take the form of a memorandum of understanding.

Bharat 6G Alliance: An Overview

  • Established by India’s Department of Telecommunications, the Bharat 6G Alliance aims to drive 6G technology development in India by bringing together industry players, academia, and research organizations.

Global Collaborations for 6G Innovation

  • India’s collaboration with both the US and Europe underscores a concerted effort to accelerate 6G innovation globally, with a focus on standards development, research, and market access for Indian firms.
