Is Omicron nature’s way of curbing the pandemic? #IndiaNEWS
In the short time since the Omicron variant was identified in South Africa in November 2021, researchers have quickly learned that it has three unique characteristics: It spreads efficiently and quickly, it generally causes milder disease than previous variants and it may confer strong protection against other variants such as Delta.This has many people wondering whether Omicron could act as a vaccine of sorts, inoculating enough people to effectively bring about herd immunity – the threshold at which enough of the population is immune to the virus to stop its spread – and end the Covid-19 pandemic.As immunology researchers at the University of South Carolina who are working on inflammatory and infectious diseases, including Covid-19, we find the characteristics of Omicron in the pandemic setting particularly intriguing. And it is these characteristics that can help answer that question.Some 4.73 billion people across the globe – about 61.6% of the world’s population – have received at least one dose of a Covid-19 vaccine. In the United States, 63.4% of the population is fully vaccinated with two doses as of late January 2022, while only 39.9% of Americans have received the booster dose. Such low levels of vaccination resulting from vaccine hesitancy and the complexities of the global vaccine supply chain cast doubt on reaching herd immunity through vaccination anytime soon.Omicron and vaccine
