                         potential need for repeated doses in theater.

                         (2) Comparison of protection afforded by RAV vaccine
                         as compared to ISG

                            (a) Field efficacy trials with the HAV vaccines
                            have not been completed. However, it is known
                            that most or all volunteers develop neutralizing
                            antibody of a titer higher than that provided by
                            ISG. Since ISG is providing only antibody
                            mediated protection, it is probable that the
                            antibody stimulated by vaccine represents a degree
                            of protection which is superior to that afforded
                            by ISG.

                         (3) Potential target populations

                         All soldiers in Saudi Arabia would be at equal risk
                         of this enterically transmitted disease.

                         (4) implication of fielding this IND product.

                         Data on over 6000 successful administrations of this
                         vaccine have been obtained. However, licensure is
                         not anticipated in the immediate future. Therefore,
                         all use of this product would come under the rules
                         governing use of IND products. Informed consent
                         possibly in an abbreviated form, may be required. A
                         protocol for large scale use will be required. Some
                         data will have to be collected from the volunteers.
                         A brochure will be required for use of the vaccine by
                         unit physicians.

                  6. Recommendation for use of this vaccine

                     a. Arrangements should be made purchase all available
                     doses of this vaccine.

 vaccine should be given to the following groups of
                     soldiers:

                         (1) Soldiers who have not had ISG yet.
                         (2) Soldiers who require updating of ISG.

               B. MSD

                  1. Status of development

                       This vaccine is in also in IND status. Versions of it
                  have been given to fewer than 100 persons, but it appears
                  to be highly immunogenic and safe. Data provided by the
                  company indicate that a preparation containing either 200
                  or 400 ng of viral protein will stimulate antibody,
                  detectable by a modified FAVAB test in all recipients.
                  However, only 10 recipients have been evaluated for each
                  vaccine schedule. The vaccine also appears to be quite
                  safe.
