To the Editor:—
In two separate letters (199:282, 1967) Drs. Paul E. Klein and Arthur F. Greenwald recount problems of reactions to administration of tetanus toxoid and of influenza vaccine. Dr. Klein warns against administration of tetanus toxoid to an individual known to be hypersensitive, and Dr. Greenwald advises multiple small doses of influenza vaccine.I strongly urge intradermal inoculations in both instances. The protection given by this method of administration is adequate, and reactions are either mild or local. Frequently they are absent altogether.
