The impact of coronavirus has continued to disrupt the lives of people on a global scale. While the attempt to contain the spread of the deadly virus continues, there’s yet another possibility of a second wave that looms over the world.According to the head of National Expert Group on Vaccine Administration for COVID-19 (NEGVAC), VK Paul, the number of Covid-19 cases and related deaths in India has surely declined in the last three weeks, however, he does not rule out the possibility of a second wave of infections in the winter season.In an interview with PTI, he said, "In India, the new coronavirus cases and number of deaths have declined in the last three weeks and the pandemic has stabilised in most of the states.""However, there are five states (Kerala, Karnataka, Rajasthan, Chhattisgarh and West Bengal) and 3-4 Union Territories (UTs), where there is still a rising trend," Mr Paul adds.On being questioned about the storage and distribution of vaccine once it is available, Dr. Paul, who is also leading the team of expert panel working towards tackling the pandemic in the country, answered by saying, "Once the vaccine is available, there will be enough resources for delivering vaccines and making it accessible to the citizens and there will be no concern about resources under those circumstances".However, while the attempt to develop a clinically approved vaccine is still underway, it is first important to understand the risks of a second coronavirus wave and how it’s affecting countries globally.
