The tetanus vaccine is used to protect against tetanus infection. This is a serious disease caused by tetanus bacteria, which is found in soil and manure. If an adult or child has a cut exposed to soil, they could get tetanus. Other ways tetanus bacteria can get into your body are through:

  • open fractures where the skin is broken and the bone exposed
  • bite wounds
  • wounds that have foreign objects, eg, wood splinters
  • crush injuries
  • burns
  • body piercings and tattoos
  • eye injuries.

Tetanus affects your nervous system and causes severe muscle contractions, mainly of your jaw and neck muscles. Find out more about tetanus.

  • Vaccination is the best method for preventing tetanus infection. 
  • This doesn't stop the bacteria growing in a contaminated wound, but it provides protection against the harmful toxin released by the bacteria.
  • You can't get tetanus disease from the vaccine, as it doesn't contain live, active bacteria.

In Aotearoa New Zealand, the tetanus vaccine is given in combination with other vaccines as 1 injection and comes in different brands. These are Infanrix-hexa®, Infanrix-IPV® and Boostrix®.

Vaccination with 3 or more doses of a tetanus-containing vaccine is required for full protection, followed by booster vaccinations throughout life. 

As part of the New Zealand childhood immunisation schedule(external link), tetanus vaccine is offered free to: 

  • babies at 6 weeks, 3 months and 5 months as Infanrix-hexa®
  • children at 4 years as Infanrix-IPV®.  

Read more about childhood immunisation.

Getting the tetanus vaccine in childhood doesn't give you lifelong immunity as the effect of the vaccine wears off with time, so booster doses are needed.

Booster doses are free for:

  • children at 11 years of age
  • adults from 45 years of age who haven't previously received 4 doses of tetanus-containing vaccine
  • adults from 65 years of age unless they've already had a tetanus booster within the past 10 years.

Read more about immunisation for older children and immunisation for adults.

Boosters may also be needed after some cuts, grazes and wounds if it's been more than 5 years since the last booster. Adults who have never had a tetanus injection will need to have a course of 3 injections at least 1 month apart. 

It's recommended that pregnant women get the Boostrix vaccine during their second or third trimester. Read more about pregnancy and immunisation.

Tetanus vaccine is given by injection in combination with other vaccines, eg, diphtheria. It's given into a muscle.

Like all medicines, the tetanus vaccine can cause side effects, although not everyone gets them.
