Recommendation 8: All biodefense contracting and granting agencies should consider covering the cost of immunizing at-risk research workers, so that this cost is not borne solely by the institutions working on government-supported programs. The committee supports the idea of central SIP administration but recommends that the SIP explore options for having a small number of satellite clinic locations around the country to reduce travel and inconvenience for other participating institutions (provided that they are able to adhere to the IND protocols).
