Dear Ms. Giacomelli:

Thank you for your facsimile dated December 5 requesting an interpretation regarding an employee's adverse reaction to a Hepatitis A vaccination. Though the inoculation was not specifically required, the fact that it was recommended by your medical clinic for the employee's required travel to Venezuela makes it a work related episode for OSHA injury and illness recordkeeping purposes. Because the episode resulted in a vaso-vagal fainting and unconsciousness, the case must be recorded on the OSHA Log.

I hope you find this information useful. If you have any further questions, please call us at Area Code (202) 219-6463.
