Gov. Phil Murphy defended his strategy Wednesday, stressing that opening eligibility on April 19 to those over age 16 does not mean everyone who qualifies will immediately come forward to be immunized. He compared it to boarding an airplane row by row, in that you don’t wait for everyone in one section to get on before calling the subsequent group.
