According to a recent SBI Ecowrap report, the average duration of the third wave for top countries is 98 days and that of the second wave is 108 days, with the third-wave peak as a multiple of second at 1.8 and second wave as a multiple of first at 5.2 (for India it was at 4.2). But, gene mutations in viruses can change these calculations. The B.1.617 variant alongside various other strains is the reason behind the deadly second wave. The virus mutates in such a way that it deceives the body's immune response and makes way to escape. This can increase risks of reinfection in those who have already developed antibodies or have been vaccinated. At the onset of the pandemic, it was believed that the younger population was devoid of perils of the virus and they remained relatively unaffected during the first wave. However, during the second wave, a higher number of children and adolescents got infected and now, they are at larger risks of becoming severely ill in the third wave.
To avert the catastrophic consequences, vaccination should be our topmost priority, especially for the children who could be the next vulnerable group. India has around 15-17 crore children in the 12-18 age bracket and it should go for an advanced procurement strategy like that adopted by developed nations to inoculate this age group. Vaccination in rural India remains a huge challenge. Behavioral dynamics of the population are also affecting vaccination drives. The children in metros are aware but a larger section in rural areas is influenced by factors including perception, trust, norms, beliefs, etc before they decide to take the shot. This challenge has to be mitigated through the setting up of robust vaccination mechanisms and awareness drives at rural levels.
