Human health implications of emerging diseases and the current situation in India's vaccine industry
Abstract
Emerging diseases are infectious diseases that pose significant threat to human health, causing millions of deaths and disabilities in the upcoming days. Periodic epidemics of new infections and old reinfections increase the global burden of disease prevalence. They can be caused by new pathogens or evolving ones, which change human behavior and environmental factors. Researchers have studied the dynamic connections between microbes, hosts, and the environment, but new infectious diseases like coronavirus disease 2019 (COVID-19), re-emerging diseases, and deliberately disseminated diseases persist despite earlier hopes of elimination. With heavy privatesector investments, Indian pharmacology now provides core Expanded Programme on Immunization vaccines to United Nations International Children's Emergency Fund, producing previously unattainable vaccines for diseases like meningitis, hepatitis B, pneumococcal conjugate, rotavirus, influenza A (H1N1), and COVID-19. India's vaccine sector has emerged, among the oriented leaders of the Bharat Biotech, Serum Institute of India, Panacea Biotech and Biological E. Specifically, the technology transferred from Western countries has benefited the sector, which produces 1.3 billion doses annually. The Serum Institute is the world's largest manufacturer of vaccines, providing measles and diphtheria-tetanus-pertussis vaccines to United Nations. The Serum Institute has developed several vaccines, including Nasovac, MenAfriVac, Pentavac, and an inactivated polio vaccine. India's success in vaccinations can be attributed to attractive investment conditions, government assistance, international alliances, and rising domestic technical talent. Despite its booming economy and technical advances, India's disproportionate share of the world's child mortality rate remains unchanged. However, the growing production and distribution of vaccinations in developing nations has initiated a new era, leading to a worldwide decline in childhood death and disease.
