WHO's chief scientist Soumya Swaminathan on Thursday said even though vaccines may not be able to provide absolute protection against different variants of SARS-CoV2, it can certainly reduce the risk of death and complications.
The World Health Organisation's chief scientist said there will be a need to be on guard in the months to come as well.
She called on Science and Technology minister Jitendra Singh and discussed various aspects of the current COVID-19 pandemic as well as a wide range of other issues.
"Even though the vaccine may not be able to provide absolute protection against different variants of virus, it can certainly reduce the risk of death and complications," a statement quoting Ms Swaminathan said.
In a country as diverse and heterogeneous as India, with multiple beliefs and faiths, it could not have been easy to embark on such a massive vaccination drive, Mr Singh said.
