The vaccine was administered to the children yesterday at the booths specially set up for the purpose.
Fifty-four per cent of the targeted children have been covered on the first day of the 3-day campaign, a Haryana Health Department spokesman said here today.
He said that about 40 lakh children would be covered during this campaign in the state.
The drive will continue for another two days when the teams would go from door-to-door to administer vaccine to children who could not come to the booths yesterday.
About 3,300 officers and officials supervised the activity apart from independent Monitors of PGIMS, Rohtak and National Polio Surveillance Project (NPSP) of World Health Organisation.
