The North Platte area is facing a shortage of the chickenpox vaccine, forcing parents to scramble to update their children's immunizations before the school year.
Published reports reveal that the West Central District Health Department ran out of the Varicella vaccination last week, but officials expect a new shipment to arrive by next week.
Department director Shannon Vanderheiden says her clinic expects to receive more than 500 doses of the vaccine.
Health service manager Tammy Hall says the clinic usually keeps only about 100 doses, and an immunization clinic held last week wiped out the clinic's supply.
This year, it's mandatory for students in kindergarten through 12th grade to have a second chickenpox vaccination.
