Mumbai Legendary superstar Amitabh Bachchan, who has been the goodwill ambassador for Polio UNICEF campaign since 2005, has revealed that his granddaughter was given polio drops in his presence on Tuesday. "Day before yesterday (Tuesday), my little granddaughter was given polio drops in my presence," the 69-year-old said here Thursday after being honoured for his work as the ambassador for polio eradication campaign. While the programme has successfully eradicated polio across India for nearly 15 months now, Bachchan insists there is still a long way to go. Bachchan said: "We must ensure that there must be no cause of polio for at least three consecutive years. We have just crossed one year and there is still a long way to go." He further added: "As a parent, I can only ask you, request you and get angry on you to continue this very noble cause."
