He further said, "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."

Raghavan, while briefing the media personnel over the Covid-19 situation in the country said, "Variants are transmitted same as original strain. It does not have the properties of new kinds of transmission. It infects humans in a manner that makes it more transmissible as it gains entry, makes more copies and goes on, same as the original."
"A phase 3 is inevitable, given the higher levels of circulating virus but it is not clear on what time scale this will occur. We should prepare for new waves," the Principal Scientific Advisor said.
"Previous infection and vaccine will cause an adaptive treasure on the virus, a new kind of changes that will escape. Therefore, we should be prepared scientifically to take care of that," he said.
He further said, "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."
"Scientists of India and all over the world are working to anticipate these kinds of variants and act against them rapidly by early warning and developing modified tools. It is an intense research program, happening in India and abroad," he added.
During the media briefing, Joint Secretary of Union Health Ministry Lav Agarwal informed that 12 states have more than 1 lakh active cases, 7 states have 50,000 to 1 lakh active cases, and 17 states have less than 50,000 active cases.
"Maharashtra, Kerala, Karnataka, Uttar Pradesh, and Andhra Pradesh have around 1.5 lakh active cases," Agarwal said.
"There are some areas of concern. Bengaluru reported around 1.49 lakh cases in the last one week. Chennai reported 38,000 cases. Some districts have recorded further and speedy Covid-19 cases, which include Kozhikode, Ernakulam, Gurugram," the Joint Secretary said.
