Even as the second wave of coronavirus infections continue to wreak havoc across the natipn, Principal Scientific Advisior to Centre K VijayRaghvan has warned that a third wave is inevitable. During a press briefing by Health Ministry on Wednesday, the top scientist said that India needs to be prepared for new waves.
"A phase three is inevitable, given the higher levels of circulating virus but it is not clear on what time scale this phase three will occur. We should prepare for new waves," VijayRaghvan said.
Explaining how variants work, VijayRaghvan said," Variants are transmitted same as original strain. It doesn't have properties of new kinds of transmission. It infects humans in a manner that makes it more transmissible as it gains entry, makes more copies & goes on, same as original."
During the briefing, the Principal Scientific Advisior emphasised on upgrading the vaccines to fight against new variants of SARS-CoV-2 virus. "Vaccines are effective against current variants. New variants will arise all over the world and in India too but variants that increase transmission will likely plateau. Immune evasive variants and those which lower or increase disease severity will arise going ahead," he said.
"Scientists of India and all over world are working to anticipate these kinds of variants and act against them rapidly by early warning and developing modified tools. It's an intense research programme, happening in India and abroad," he further added.
VijayRaghvan also suggested laboratories to prepare a map of all possible changes that can happen due to the coronavirus, adding that only sometimes can viruses erode immunity so rapidly.
