In a swipe at the government, Congress leader Rahul Gandhi said on Friday that July has come, but vaccines have not, drawing a sharp retort from the BJP which cited figures to ask if spreading ''confusion'' is the opposition party's undeclared policy. <br />''July has come, vaccines have not. Where are vaccines,'' Gandhi tweeted. <br />The BJP hit out at him and claimed that people often ask why maturity, wisdom, and responsibility have not come to the Congress leader despite the passage of 51 Julys, a reference to his age.
