Can I get more than one vaccine at a time?

Page last updated 09 May 2018


It is safe and effective to receive more than one vaccine at the same time. In fact, many vaccines are already combined, for example, measles, mumps, rubella (MMR) and diphtheria, tetanus, and pertussis (whooping cough) (dTpa). 

Your doctor may choose to give you the injection in different locations, for example, an arm and a leg. There are some vaccines that cannot be given at the same time, such as BCG (Bacillus Calmette–Guérin) for tuberculosis (TB) and varicella (chicken pox), so seek advice from your GP or healthcare practitioner about the amount of time needed between such vaccinations.
