As part of a mounting campaign to reach people and let them know medical assistance is at hand, the U.S. Public Heath Service is distributing a film, “To Open a Door,” which chronicles methods employed in a largely Negro and Puerto Rican section of Newark, N.J., where a “crash program” was undertaken to induce residents to accept the Sabin oral vaccine against polio. Clergymen, like the Baptist minister shown here urging his church members to take the vaccine, played a key role in the project. Officials estimated that 80 per cent of an “almost unreachable” population received the vaccine. Credit Must Read: RELIGIOUS NEWS SERVICE PHOTO (MWN-NY-1D-65-NBM)
