Public health officials say many Oregon teenagers aren't getting the vaccinations they should be getting at their age.
Federal figures show that 84 percent of teens have been vaccinated against tetanus, diphtheria and pertussis, or whooping cough. That's above the national average.
But, The Oregonian reports, only 65 percent have been immunized against meningococcal disease disease.
About 60 percent of Oregon girls have had one dose of the HPV vaccine against human papilloma virus, but only a third have had all three doses. Among boys, the corresponding numbers are much lower: 25 percent and 6 percent.
Health officials say it's unknown how many teens get annual flu shots, but they suspect the number is low.
