I had mine last week and it is either combined with tetanus and polio, or just tetanus. Not sure if its' the same for kids.
Im in the process of getting all my DS carers (grandparents etc) to get the booster, as it's recommended in Syd at the moment. \
Also they say in most cases, it's adults who pass it on not kids and that's why they're pushing for adults to have boosters asap .xo
