Oral or Parenteral
Occasionally, an individual may ingest vaccine accidentally or may be injected inadvertently by the intramuscular or subcutaneous route with a dose of vaccine.

These are not recommended routes of administration. No harm has been recorded from such events.

Management

It is prudent to follow the individual clinically and to examine the site of injection for any lesions in the one to two weeks following administration. If the injection is subcutaneous, some individuals will respond with a normal cutaneous response.
