For the majority of vaccine-preventable infectious diseases the
concept of vaccination at an early age in healthy children is wellestablished.
The basic vaccination programs against diphtheria,
tetanus, pertussis have been implemented worldwide decades ago
and have significantly reduced the burden of disease throughout
the world. Today’s vaccination schedules include other diseases
like Hib and hepatitis B, even in most of the developing countries.
While for these diseases childhood vaccination is not debated,
rabies PrEP is rarely considered. The reasons may be several.
Past rabies vaccines derived from nerve tissue were reactogenic
and often resulted in severe adverse reactions, and therefore were
only used in PEP cases where the side effects had to be accepted,
taking into account the fatal consequences of not administering
the vaccine. However, modern cell culture vaccines like HDCV,
PVRV, PDEV or PCECV are safe and well tolerated. Their reactogenicity
profile is not different from other childhood vaccines.
Vaccination of children could also be established for rabies, from
a safety as well as immunogenicity point of view. The scientific
mechanism behind the immune response is the same: The contact
with inactivated pathogen (in the case of rabies: inactivated
whole virus) leads to a T-cell mediated immune response, generating
memory cells, which in case of contact to the causative organism
(or a booster dose of vaccine) triggers an anamnestic response
