The state Department of Human Services is recommending revaccinations for about 150 Southern Oregonians after it discovered some vaccines have been stored improperly.

The revaccination recommendation also includes nearly 22,000 other people in 12 Oregon communities. Dr. Mel Kohn, public health director for DHS, said in a news release that the vaccines are safe, but they may have lost potency because they were stored at higher-than-recommended temperatures.

Most of the affected vaccines were for protecting children against tetanus, diphtheria, pertussis, polio, measles, mumps, rubella, haemophilus influenzae type B, hepatitis A and B, human papilloma virus, viral influenza and pneumonoccal disease. Some adult vaccines may be affected because all vaccines are usually stored in the same area.

Providence officials said the recommendation includes people who were vaccinated at clinics operated by the Providence Health System, including Doctors Clinic, Jacksonville; Medford Family Practice, Medford; and Shady Cove Clinic, Shady Cove.

Jim Sellers, a spokesman for DHS, said letters are being sent to the people who should consider revaccination.
