rigors. If there is likely to be a delay in medical evaluation, most authorities support this
strategy, but there is no proof that such early self-treatment will lower the incidence of OPSI.
The use of prophylactic measures should never be allowed to engender a false sense of
security, because OPSIs involving pneumococcal infection have been reported in patients
receiving penicillin prophylaxis and vaccinated patients (68).
