Comment: While the Pneumonia vaccine has been introduced relatively later in India, and still faces a lot of resistance due to its high price (almost 4000 INR ~ 70 USD), this is good evidence that shows that it really reduces the risk of Invasive Pneumonia in the children. Data from India would be better, but is unsurprisingly unavailable.
