Daily Press file photo Sandra Gibbs, 12, faces up to the challenge of being immunized by Michelle Johnson today in 1993 at Gladstone Middle School. School nurse Joan DeKeyser said state law requires students to be immunized. About 275 students were given booster shots for tetanus, polio, measles, mumps and rubella. School employees, too, were immunized with flu, vaccine, tetanus boosters and the last of three hepatitis B shots. About 400 vaccines were administered through the health department. Daily Press photographer Doug Brooks later put down his camera to receive a flu shot. No, Brooks’ grimace was not recorded for posterity.
