The Australian Medical Association and the State Government are both concerned that a recently posted billboard in Northbridge, displaying links to an American anti-vaccination group is promoting dangerous misinformation regarding vaccinations, particularly regarding the risks associated with vaccination and myths regarding long term consequences such as autism, autoimmune disorders and chronic disease. The health authorities are attempting to have the billboard removed as the message puts lives at risk and the information available at the link provided has been comprehensively and internationally proven to be false.

All vaccines used in Australia have been through a testing process before being licensed by the Therapeutic Goods Administration. This ensures that each vaccine is safe to administer and proven to be effective based on clinical trials. The safety of vaccines are constantly monitored as millions of doses are administered after licensing. Scientists are also currently working to identify risk factors that can lead to conditions like cancer, stroke, heart disease, autism and autoimmune diseases. If immunisations were identified as a risk factor if would have been noted in the clinical research and immediately reported and responded to, scientists, doctors , health departments and governments are keen to improve outcomes for people and communities.

The main ingredient of vaccines is the disease-causing virus, bacteria or toxin, but other components are required to make the final vaccine as safe and effective as possible. Both killed and live vaccines work by stimulating the immune system to produce antibodies that stay in your system to protect you in the future should you come into contact with the active germ. Live vaccines contain viruses that have been weakened in the laboratory, to produce a strong immune response, but not the disease.

A complete list of ingredients for each vaccine is available in the patient information leaflet of the vaccines. These ingredients include products used in the making of a vaccine, even though most are only needed during the production process and are removed or found in minute amounts in the final vaccine.

One of the common concerns regarding vaccine contents has been the presence of mercury in vaccines. Thiomersal is a preservative that contains small amounts of mercury. It is used to prevent the growth of bacteria or fungi in the vaccine. High doses of mercury can be toxic to the brain and other organs. No harmful effects have been linked with the level of thiomersal present in vaccines. Although there has been concerns in the past that thiomersal can cause autism, there is no scientific evidence that this is the case. The world health statements regarding the absence of a link is available to read at . Also available is the National centre for Immunisation research and Surveillance Thiomersal fact sheet at  Thiomersal is no longer used in any of the vaccines routinely given to babies and young children.

Some vaccine ingredients could be toxic at high doses, at low dose even a highly toxic substance can be safe, for example many adults have Botox, one of the most toxic substances known injected into their face regularly. Aluminium is a component in some vaccines to help the vaccine work more effectively. The average person takes in an estimated 30 to 50 mg of aluminium daily from food and water. Those vaccines containing aluminium typically contain 0.125 to 0625mg per dose. Formaldehyde is in car exhaust, household products and furnishings such as carpets, cosmetics, felt tip markers and paints. it is used during manufacture of some vaccines and is removed except for a tiny trace. 

No vaccine has ever contained antifreeze.

The Australian Department of Health has a range of fact sheet regarding vaccine contents, safety and side-effect possible available at

Vaccination has been one of the greatest breakthroughs in modern medicine, no other medical intervention has saved more or improved more lives. We no longer see smallpox and polio is almost eradicated. The diseases such as diptheria and tetanus are so rare, it is easy to underestimate the importance of vaccination. After a scare about the safety of the whooping cough vaccine in the 1970s and 80s in the UK, parents stopped vaccinating their children against the disease, leading to 3 epidemics and at least 100 children dying of whooping cough .
