Pandemic Third Wave Response: The Feel-Good Factor And The Expendables!

An encompassing aura of complacency seems to have spread across India, probably faster than the Variant of Concern, Omicron itself.

This sense of complacency or the feel-good factor, of course, has various ‘sound’ reasons varying from almost proven trends internationally, advisory-driven perceptions, comments by experts and the variant being considered as an immunity booster, even more powerful than the precautionary vaccine dose. So far, only the South African experience shows exponential rise in numbers accompanied by equally rapid decline after a few days and that Omicron leads only to a mild disease, particularly for the fully vaccinated. Fatality figures, however, do not follow the SA standards as a lot of people have died or still dying in

This doubt permeates even the vaccine development process: even if a safe and effective vaccine is ultimately found, would it be able to provide long-term immunity in vaccinated persons. Now, the first confirmed case of a COVID-19 reinfection in Hong Kong reaffirms this doubt. A 33-year-old man in Hong Kong got COVID-19 positive in late March 2020 and recovered in the first part of April. Then in August he visited Spain and while returning to Hong Kong he was found positive again at the airport. In the first he was symptomatic while he was asymptomatic in the second infection. Hong Kong researchers did a genome sequencing on the patient and confirmed reinfection, revealing that in the first instance he was infected with the prevalent Asian strain of SARS-CoV-2 an
