Diphtheria and tetanus toxoid is a combination vaccine. It helps protect against diphtheria (a contagious bacterial infection that affects the linings of the nose and throat) and tetanus (a bacterial infection that causes painful contractions of the neck and jaw muscles).
It works by getting your body to produce antibodies (proteins that are produced by the immune system which help in fighting infections) to protect you against the bacteria that cause diphtheria or tetanus.
Diphtheria and tetanus toxoid vaccine is to be given intramuscularly (into the muscle).
Your doctor or nurse will administer the injection for you.
The total number of injections you will receive will be decided by your doctor.
Ensure that you keep all appointments with your doctor so that you do not miss any doses. Your doctor also needs to regularly monitor your response to Diphtheria and tetanus toxoid vaccine.
If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.
