Washington: India is a leading producer and exporter of vaccines but two-thirds of Indian children do not receive vaccinations on time which makes them susceptible to diseases and contributes to untimely deaths, according to American researchers.
"This is a systemic problem," said the study's lead author, Nijika Shrivastwa, who recently finished her doctorate in epidemiology at University of Michigan (U-M) and is now at the South Carolina Department of Health and Environmental Control.
"Immunising a child six months after the recommended time period can have dramatic implications for a child's vulnerability to diseases," Nijika said.
Although India is a leading producer and exporter of vaccines, the country has the greatest number of deaths among children under 5, the majority are from vaccine-preventable diseases.
"Every year, 26 million children are born in India - the greatest number by far of any country in the world," said Matthew Boulton, senior associate dean for global public health at the U-M School of Public Health.
"Adding vast numbers of new children who need vaccination, while the older ones remain under or unvaccinated because of immunization delays, is like walking too slowly on a moving treadmillyou continuously fall further back," he said.
"Approximately, 95 per cent vaccination is required in a population to successfully stop measles outbreaks. India's childhood vaccination rate is simply too low to successfully control transmission of disease and prevent measles-related childhood illnesses and deaths," Boulton said.
