Objective] To observe the immunological effect of intramuscular cholera vaccine.
Study on the prophylaxis against ETEC diarrhea by locally produced oral cholera vaccine
Methods The mice were immunized by different doses of cholera vaccine. Titer of antiserum against cholera strain and toxin were tested by indirect enzyme-linked immunosorbent assay (ELISA).
The researchers say the experimental cholera vaccine produced reactions in the immune system and in areas of mucosal tissue.
But research in Japan may lead to rice plants that contain a cholera vaccine that does not need to be kept cold.
