Tetanus Immunisation

tetanus immunisation


All children and adults should be immunised against tetanus. See your practice nurse if you think that you are not fully immunised.

What is tetanus?

Tetanus is an infection caused by a bacterium called Clostridium tetani, which can attack the muscles and nervous system. Tetanus is a serious infection which can even be fatal. Tetanus bacteria (germs) live in the soil and dirt. The bacteria may get into your body through a cut or a wound in the skin. The bacteria make a toxin (poison) which causes the illness.

Even small wounds such as a prick from a thorn can allow enough bacteria to get into the body to cause tetanus. The illness takes up to 21 days to develop, sometimes more. Therefore, you may have forgotten about a small cut before the illness starts.

The vaccine

For young children, tetanus vaccine is normally part of the combined DTaP/IPV(polio)/Hib vaccine - this stands for 'diphtheria, tetanus, pertussis (whooping cough)/polio/Haemophilusinfluenzae type b' vaccine, which is given as part of the routine childhood immunisation programme.

For adults and teenagers who receive tetanus immunisation, a combined tetanus, diphtheria/polio vaccine (Td/IPV(polio)) is normally used.

The vaccine stimulates your body to make antibodies against the tetanus toxin. These antibodies protect you from illness should you become infected with this bacteria.

Tetanus immunisation timetable

All children are offered tetanus immunisation as part of the routine immunisation programme. A full course of tetanus immunisation consists of five doses of vaccine as follows:

  • Primary Course: Three doses of vaccine - as DTP/IPV(polio)/Hib at two, three and four months of age.
  • Booster Dose

  • 4th dose-Three years after the primary course - pre-school booster.
  • 5th dose,Aged 13-18 years - the school leaver booster - as Td/IPV(polio).10 years after the 4th dose - as Td/IPV(polio).

The primary course of three injections gives good protection for a number of years. The fourth and fifth doses (boosters) maintain protection. After the fifth dose, immunity remains for life.

Adults - are you immunised?

Some adults have not been fully immunised against tetanus because routine immunisation for children was not introduced until 1961. Men serving in the armed forces from 1938 onwards were offered tetanus immunisation. So, some older people may still be at risk.

The course does not need to be started again if an injection is delayed. A late injection is sufficient to catch up, even if you have it years after it was due.

Do I need a dose of tetanus vaccine after cuts, bites, etc?

  • If you are not immunised or up-to-date with boosters then an injection of vaccine is usually advised.
  • If you are up-to-date with tetanus immunisations, then you do not need a tetanus vaccine.
  • If your wound or injury is considered to be high risk for tetanus (for example, where there has been significant contact with soil or manure) then an injection of human tetanus immunoglobulin is usually given, regardless of whether your have been immunised against tetanus or not. This gives extra protection against tetanus.

I am going abroad - do I need a tetanus immunisation?

Usually not if you are up-to-date with your immunisations. However, if you are to travel to areas where medical attention may not be available, then a dose of vaccine may be advised. This is even if you have had five previous injections. In particular, if it has been more than 10 years since your last injection. This is a precautionary measure in case you have a very dirty wound and do not receive antiserum. Your doctor or practice nurse will advise.

Are there any side-effects from the tetanus vaccine?

It is common to get a little redness and swelling around the injection site, which goes after a few days. Some people feel slightly unwell for a day or so, with a mild headache, slight aching of the muscles and a mild fever. Severe reactions are extremely rare.

Who should not receive the tetanus vaccine?

If you are unwell with an illness causing a fever, it is wise to postpone an injection until the illness has gone (except if the dose is needed after a cut or wound). Also, you should not have another injection of vaccine if a previous injection caused a severe reaction. The tetanus vaccine is safe if you are pregnant or breast-feeding
