There is no evidence to suggest that existing Covid vaccines do not work on the Omicron variant, Union Health Minister Mansukh Mandaviya said on Tuesday.
"While there is no evidence to suggest that existing vaccines do not work on Omicron, some of the mutations reported on spike gene may decrease the efficacy of existing vaccines," he told the Rajya Sabha in a written reply.
Responding to a question on whether the vaccines being administered in the country are effective to develop immunity against the Omicron variant, he informed the house that there is limited available data, and no peer-reviewed evidence, on vaccine efficacy or effectiveness to date for Omicron. However, vaccine protection is also by antibodies as well as by cellular immunity, which is expected to be relatively better preserved.
