Do Vaccines Work On Omicron Sub-Variant? What WHO's Soumya Swaminathan Said
The idea of attaining herd immunity through natural infection to fight against Covid is "foolish" as there are huge costs to be paid, Chief Scientist at the World Health Organisation Dr Soumya Swaminathan told NDTV today, adding that the WHO has always maintained this stand. About the new Omicron sub-variant, she said that BA.2 is more potent than BA.1 and its transmission is more than other sub-variants. It's taking a grip in some countries, especially India and Denmark, she added.
