What happens if intradermal injections of rabies vaccine are partially or entirely injected subcutaneously?
Reported are the results of a study with the Thai Red Cross two-site intradermal purified Vero-cell rabies vaccine (PVRV) schedule that was deliberately injected into subcutaneous tissue. The 44 healthy nonimmune Thai adults who were enrolled in the study were randomly assigned to the following groups and given PVRV as shown: group A (two intradermal injections on days 0, 3, and 7); group B (one intradermal and one subcutaneous injection on days 0, 3, and 7); and group C (two subcutaneous injections on days 0, 3, and 7). Neutralizing antirabies antibody titres were determined on day 14 using the rapid fluorescent focus inhibition test. High rabies antibody titres were obtained for all three groups. These results suggest that the economical and safe Thai Red Cross intradermal PVRV regimen could be used in selected general health care facilities.
