Immunization screening:

The threshold dose of PA for rabbits was chosen by injecting rabbits intramuscularly (i.m.) on days 0 and 14 with either 10 g, 1 g, 0.1 g, 0.01 g, or 0 g of PA (List Biological Laboratories, Campbell, Calif.) diluted in PBS in a volume of 0.5 ml, each adsorbed to 1 mg of aluminum per ml … The primary and secondary antibody response profiles were examined by injecting rabbits i.m. with 50 g of PA/Alhydrogel on days 0 and 21 and collecting blood periodically to test serum for the presence of antibodies to PA and TNA titers in the serum.

2.3. Protection against aerosol exposure

Rabbits were injected i.m. with 0.1 g of PA/Alhydrogel and boosted with 0.1 g of PA/Alhydrogel 4 days (day 86), 8 days (day 82), or 12 days (day 78) before aerosol exposure on day 90 following the primary immunization. …
