After some of its leaders questioned the approval process for Bharat Biotech’s Covid-19 vaccine, the BJP on Sunday hit out at the Congress. Party president J P Nadda alleged that whenever India achieves something commendable the opposition party comes up with “wild theories” to “ridicule” the accomplishments. Congress and the Opposition is not proud of anything Indian. They should introspect about how their lies on the COVID-19 vaccine will be used by vested interest groups for their own agendas. People of India have been rejecting such politics and will keep doing so in the future, the BJP chief said in a series of tweets.
