WHO Says that the Delta Covid Variant is Becoming Globally Dominant

According to the World Health Organization’s chief scientist, the Delta version of Covid-19, which was initially found in India, is becoming the disease’s global dominant variant.

Soumya Swaminathan expressed concern that CureVac’s vaccine candidate failed to fulfil the WHO’s efficacy criterion in a trial, especially given the increased need for new, effective vaccines due to highly transmissible variations.

Despite improving vaccination rates, the Delta form has seen a sharp increase in infections in the United Kingdom, and Germany’s top public health expert anticipated it would quickly become the dominant variant there.

After record new infections in Moscow, largely with the new Delta form, fuelled worries of a third wave, the Kremlin blamed a rise in COVID-19 cases on a lack of immunizations and “nihilism.”

CureVac cited strains of the Coronavirus when it said this week that their vaccine was only 47% effective at preventing sickness, falling short of the WHO’s 50% target.

According to the company, there were at least 13 variations circulating in the research population. Given the effectiveness rates of similar mRNA vaccines from Pfizer, BioNTech, and Moderna, Swaminathan believes the world was expecting more from CureVac’s candidate.

Despite accounting for only about 5% of new worldwide infections and 2% of deaths, WHO experts said Africa remains a source of concern. According to WHO emergency programme head Mike Ryan, new cases in Namibia, Sierra Leone, Liberia, and Rwanda have risen in the last week, but vaccination access remains limited.
