Pneumococcal disease: Closing the gap
oday, India is home to 99 million elderly people. By 2050, the number of elderly in this country will have gone up to 300 million1. With an increase in life expectancy from 32 years at the time of independence to 67.14 years in 20121, 10% of the population finds itself labeled as ‘senior citizen’....

Inevitably, age brings with it comorbidities, immune senescence and pneumococcal disease.
