'

Diphtheria toxoid is an inactivated form of the diphtheria toxin. It is used in vaccines to protect against diphtheria.

Diphtheria toxoid looks like diphtheria toxin, but it is not toxic. When it is injected into the body, it stimulates the body to produce antibodies to the diphtheria toxin. These antibodies will then protect the person from diphtheria if they ever come into contact with the toxin.

Diphtheria toxoid is used in vaccines to protect against diphtheria. It is most commonly used in combination vaccines, such as the Tdap vaccine, which protects against tetanus, diphtheria, and pertussis (whooping cough). In the United States, the Tdap vaccine is recommended for all people over the age of 11.

Diphtheria toxoid can also be used in a vaccine to protect against diphtheria and other infections. This type of vaccine is known as a combination vaccine, and it can be used to protect against several different infections at once.

Diphtheria toxoid can also be used to protect against infections in people who have not been vaccinated before. In this case, the vaccine may be given in a single dose or in a series of doses.

In summary, diphtheria toxoid is an inactive form of diphtheria toxin used in vaccines to protect against diphtheria. It is most commonly used in combination vaccines, such as the Tdap vaccine, and it can also be used in a single dose or in a series of doses to protect people who have not been vaccinated before.
