Abstract
Dried typhoid vaccines were prepared by freeze-drying of heat-inactivated phenolized-cell suspensions and by an acetone-killed and dried technique. Portions of the dried powder obtained by each method were compressed into tablets. Tests with the products showed that drying and making of tablets did not affect the ability of the vaccines to protect mice or elicit antibodies in rabbits.
