The Left parties Monday alleged that Prime Minister Narendra Modi "abandoned" his government's "discriminatory" immunisation policy, "fearing" a Supreme Court directive for universal free vaccination, and under Opposition pressure. <br /> <br />Modi in an address to the nation announced that the central government will provide free vaccines to states for all above 18 years starting June 21. <br /> <br />"Trying to defend his dubious discriminatory vaccine policy by passing the buck on to State governments. Now Modi abandons his policy, fearing a Supreme Court directive for a free and universal vaccination programme by the Centre," tweeted CPI(M) general secretary Sitaram Yechury.
