The world has gained a new weapon in the war on malaria, among the oldest known and deadliest of infectious diseases: the first vaccine shown to help prevent the disease. By one estimate, it will save tens of thousands of children each year.India’s Bharat Biotech will be producing part of the world’s only malaria vaccine that has been developed by Pharma major GSK, and was recently approved by WHO (World Health Organisation).Malaria kills about 500,000 people each year, about half of them children in Africa. The vaccine, called Mosquirix, is not just a first for malaria — it is the first developed for any parasitic disease. Parasites are much more complex than viruses or bacteria, and the quest for a malaria vaccine has been underway for a hundred years. It is a game changer for public health and infant mortality. Creating a vaccine to protect against a bacteria or a virus is hard enough. But parasites are more complicated organisms.
