Ty21a strain of Salmonella typhi is a live vaccine ingredient for the prevention of typhoid fever.
MFDS ingredient code M267589
Ty21a strain of Salmonella typhi is an attenuated live strain, a variant of the typhoid bacillus Salmonella typhi. This ingredient is used in vaccines to induce an immune response in the body to prevent typhoid fever infection. It is primarily administered in oral vaccine form.
This live strain multiplies in the human body in an attenuated form, prompting the immune system to recognize it and produce antibodies. The immunity formed in this way helps to respond quickly and effectively when actually exposed to the typhoid bacillus.
Approved uses differ by product. Check each product's information for its actual use.
The Ty21a strain typhoid vaccine uses live attenuated bacteria, unlike inactivated vaccines, to enhance the intestinal immune response. This allows for oral administration and differentiates it by having a relatively long duration of immunity.
