India shows why we will all need COVID vaccine booster shots

COVID mutations could spin out of control if situations like that in India continue to occur. Dr Khan explains how boosters will work and examines the news about a new malaria vaccine.
The mass production of the COVID-19 vaccines has been nothing short of a feat of medical science, and the rollout across many countries has been incredible. But there is a fly in the ointment – two, to be precise: How long does the protection provided by a vaccine last? And, will the vaccines be effective against emerging variants? The tragic situation unfolding in India is a case in point when it comes to fighting new variants of the coronavirus. India has a population of 1.4 billion and had an excellent start to its vaccination programme. It is also home to one of the biggest manufacturers of vaccines in the world: the Serum Institute of India (SII), which was making and exporting millions of vaccines to other countries as cases were coming down in India. But due to recent public gatherings, and the early easing of lockdown measures, India has found itself at the epicentre of the pandemic, setting global records for daily cases and deaths. The world has watched in horror as scenes of people struggling to breathe outside hospitals have streamed across news networks.
