before a vax can be given in australia it has to go through so much testing. its has to be approved by the therapuetic goods act, and a few other agencies that deem it safe for use. its the same as any medication.

it is then monitored closely and any reaction is listed on a database.
if you want true AUSTRALIAN statistics go the department fo health or beuro of statistics it will give u the number of deaths, reactions etc per people immunised.

also the vax used in america is slightly different to here.

nothing in life is 100% safe this we must remember.

also the programme is a school based programme and free. the 16-26 programme has finished, if you havent had your first jab yet you have to pay and i can tell you its around $300 per shot that you pay for out of your pocket. this is the incentive either get it at 13-16 for free or pay $900 later in your life.

the immunisations are tested on the age group they are aimed at. the australian government and Theraputiuc goods act requires this, where as in america it is a requirement. so in australia yes it has been tested on people of the same age as those recieving it as part of the programmes.
