Summary

The improper use of needles and syringes and contamination of multidose medication vials can result in transmission of bloodborne pathogens (e.g., hepatitis B virus {HBV} and human immunodeficiency virus {HIV}) and other infectious agents from patient to patient (1-6). Since September 1993, CDC has received reports from health-care providers and public health departments in two U.S. cities regarding improper infection-control practices during vaccination of employees at worksite vaccination programs. These practices could potentially have exposed vaccine recipients to infectious agents. This report summarizes the preliminary findings of an ongoing investigation of these reports.(*)

District of Columbia. A company occupational health officer reported that a physician retained to administer influenza vaccine to employees had been observed reusing needles to subsequently vaccinate other employees. Investigation by the local health department confirmed that the physician vaccinated a series of employees by using the following routine: the physician first aspirated several doses of vaccine from a multidose vial into a syringe, inoculated an employee, and then, after wiping the needle with an alcohol swab, used the same needle and syringe to subsequently inoculate another employee.

Pennsylvania. A supervisor at a worksite reported that a physician retained to administer influenza and pneumococcal vaccines to employees had been observed puncturing multidose vials of vaccine with needles that had been used previously to inoculate patients. Investigation by the local health department confirmed that the physician first aspirated a dose of influenza vaccine into a syringe and inoculated an employee; then, using the same syringe and needle, aspirated pneumococcal vaccine from a multidose vial of that vaccine and inoculated the same person. Although a new syringe and needle were used for each employee, the physician repeatedly punctured the multidose vials containing pneumococcal vaccine with used needles.

Follow-up. Persons who received vaccinations at these worksites have been counseled and offered serotesting for bloodborne pathogens (e.g., HBV and HIV). Further investigation and follow-up of the vaccine recipients are ongoing.

Editorial Note

This report describes examples of improper use of needles, syringes, and multidose vials that could potentially result in patient-to-patient transmission of infectious agents. For example, bacteria can survive in and have been transmitted to patients through contaminated multidose vials and syringes (1,2,7). HBV has been transmitted by contaminated multidose medication vials and reuse of contaminated needles and syringes (3,4). In addition, nosocomial patient-to-patient transmission of HIV has occurred when needles and syringes were reused without being properly sterilized (5) or were inadvertently reused between patients (6). Finally, in a laboratory simulation of improper clinical use, syringes and multidose vials became contaminated with viruses (8).

Reports of transmission of infectious agents by a single injection with a contaminated needle and syringe or from a multidose vial have been limited. However, the frequency with which injections are administered in health-care settings increases the likelihood of infection transmission if proper infection-control practices are not followed when medications, vaccines, and other parenteral substances are injected. The following infection-control principles are consistent with previous CDC recommendations and should be adhered to by health-care providers and all other persons who administer parenteral substances by injection (9,10):
