Intradermal administration of viral vaccines.
Intradermal administration maybe useful in lowering the cost of vaccination against hepatitis B significantly, and may also be helpful for the rapid induction of antibodies, reversing non-responsiveness, improving postexposure prophylaxis and immunising immunocompromised people. In addition, delayed type hypersensitivity skin reaction to the vaccine could serve as a useful marker for the acquisition of T helper type 1 immunoreactivity in vivo. However, there are some disadvantages when using intradermal vaccinations, including the requirement for skilful administration, the absence of approval from licensing authorities, the development of local skin reactions and a lower antibody response when 1/10 of the standard vaccine dose is used. This requires that appropriate vaccination regimens, including the correct vaccine dosage, and vaccination schedule are followed. In the future, a similar vaccination strategy might also be applied for the prevention and control of other infectious diseases. Copyright 1998 John Wiley & Sons, Ltd.
