County Workers Stored 25 Types of Vaccines at Improper Temperatures. Now, 23,000 Ventura Residents Must Be Re-Immunized.
Some 23,000 patients who received vaccinations at Ventura County clinics between October 2017 and November 2018 must be re-immunized after it was discovered that county workers had stored the vaccines at improper temperatures.
To be fully effective, most vaccines must be stored at temperatures of 35 to 46 degrees Fahrenheit. But after a change in package processing was implemented, some of the vaccines dropped well below the safe range. The county is now “scrambling” to contact tens of thousands of patients, the Los Angeles Times reports.
Of those contacted so far, less than 5% — or about 1,200 —have come back for a second vaccination, raising serious public health and safety concerns. The county is trying to spread the word that the revaccinations are free and perfectly safe to receive a second time.
Twenty-five types of vaccines, including flu and HPV, as well as the antibiotic penicillin, may have been affected.
