The
rash is erythematous and pruritic in most instances
and is most intense surrounding the vaccination site.
The degree of erythema is intense and the rash may be
raised or flat, with an urticarial border. The rash
tends to be symmetrical and often involves the palms
and soles.
Intense itching may accompany the rash and scratching
can lead to bacterial superinfection.
