The announcement comes after multiple real-world investigations revealed that the strain, which is extremely resistant to antibodies evoked by vaccination as well as antibodies from previous infections, reduced the efficiency of most commonly used doses to under 40%.

The World Health Organization’s technical advisory group said on Tuesday that current Covid-19 vaccinations may need to be upgraded to guarantee that they are effective against novel variations like Omicron. The announcement comes after multiple real-world investigations revealed that the strain, which is extremely resistant to antibodies evoked by vaccination as well as antibodies from previous infections, reduced the efficiency of most commonly used doses to under 40%.

“The composition of current Covid-19 vaccinations may need to be changed,” the panel of independent experts stated in a statement, “to guarantee that Covid-19 vaccines continue to deliver WHO-recommended levels of protection against infection and illness by VOCs, including Omicron and future variations.” The WHO set a 50% efficacy threshold for coronavirus vaccines, which each of them met when tested against the variety that first circulated in 2020, but which has since been lowered due to the emergence of the Sars-CoV-2.

TAG-CO-VAC, a WHO panel, has asked vaccine manufacturers to generate and provide data on the performance of Omicron-specific vaccines for the time being. Omicron-specific vaccines are being tested by several companies, including Moderna and Pfizer, while pan-coronavirus vaccines are being tested in clinical trials by others. Pan-coronavirus vaccines are challenging to develop.

Talking about the recent update, India reported nearly 200,000 new Covid-19 cases in a significant rise, with as many as 194,720 persons testing positive, according to statistics released by the Union health ministry on Wednesday. Daily fatalities also increased, with 442 lives lost owing to the viral sickness, according to the report. In a troubling development, the number of active cases has risen to 955,319, an increase of 133,873 cases since Tuesday’s bulletin. In addition, 60,405 more patients were discharged, bringing the total number of people who have recovered to 34,630,536. According to the data, recoveries, active cases, and deaths account for 96.01 percent, 2.65 percent, and 1.34 percent of the total caseload, respectively. On the Omicron front, the infection count has risen to 4868, up from 407 on January 11 when the new variant’s data was released.
