Is the Coronavirus vaccine a panacea for everything? Does a vaccine mean all our problems with Covid19 are solved? Dr Gagandeep Kang India's top vaccine scientist says we will have a vaccine in the next 6-12 months but it's just one part of the answer. We have absolutely no knowledge of efficacy of ANY vaccine at this point. We don't even know if it will work in the elderly. Dr Kang spoke to Govindraj Ethiraj, founder IndiaSpend and DataBaaz on the intense race for vaccines in tackling the Covid-19 health crisis and the components of a cure for Coronavirus. Dr Kang is a professor at Christian Medical College, ( CMC ) Vellore.
