Parents who choose not to immunize their children are putting their own children, their children’s friends, and others in the community at risk. Find out more at

There are no proven alternatives to vaccines.

  • Homeopathic remedies, such as Nosodes, chiropractic manipulations and other treatments do not protect against vaccine preventable illnesses.Health leaders across Canada support this campaign

Vaccines do not harm nor overwhelm the immune system.

Vaccines work and are safe.

  • Immunizations are credited as being one of the ten greatest public health achievements of the 20th century. They have been responsible for saving more lives in Canada within the past 50 years than any other health measure. Prior to routine immunization, many Canadian children died from preventable diseases such as diphtheria, measles and polio. A comparison of vaccine preventable diseases in Canada in the pre-vaccine era and 2007-2011 shows a steep decline in these diseases.
  • The MMR vaccine does NOT cause autism. Studies have clearly proven that the MMR vaccine does not cause autism. This mistaken belief sometimes arises because the signs of autism may appear around the same time that children receive the MMR vaccine, which has led parents to believe that the latter causes the former. However, this is not true. There is no difference in autism rates between vaccinated and unvaccinated children.

Canada has an excellent vaccine safety record and safety monitoring system.

  • In Canada, each vaccine undergoes safety checks and continuous monitoring. Extensive studies take place, first in the lab and then in many human subjects (clinical trials) before a vaccine can be licensed. These studies follow strict criteria with regular checks and balances to ensure that they meet carefully set standards. Even after a vaccine has passed through all of these quality and safety measures and is available on the market, it must still go through routine monitoring to make sure that there are no long-term adverse effects.

The diseases that vaccines were designed to prevent still exist. Children today still need to be vaccinated.

  • In 2013, measles accounted for 145,700 deaths around the world, or approximately 16 deaths every hour. From 2000 to 2013, the measles vaccine prevented 15.6 million deaths. February 2015 saw outbreaks of measles in Canada with the first cases appearing in Ontario and Quebec. By the end of March, 180 cases of measles had been reported as part of these outbreaks. Measles can be associated with severe and life-threatening complications.

‘Herd immunity’ or relying on community uptake of immunizations to protect everyone does not occur with every type of vaccination and even when it works, still requires the majority of the population to be vaccinated.

  • Herd immunity occurs when a large proportion of the population is immune to a particular disease and thus offers protection to individuals who are not immune. The greater the percentage of immune people in the population (through vaccination), the less likely it is that a non-immune person will come into contact with an infectious person. Children who are immunocompromised and cannot be vaccinated rely on herd immunity to protect them from harmful infections.

Delaying vaccines (or changing the schedule) is harmful as protection is not achieved when the child is at highest risk.

  • The age at which each vaccine is given is specifically timed to coincide with the period when the infant or child is most at risk for the infection and is capable of responding to the vaccine.

We know parents want to do what is best for their children. They have the right to accurate information and an obligation to use it when making vaccine-related decisions for their children.

All physicians caring for children must have the knowledge and tools to appropriately discuss immunizations, vaccine safety, and vaccine preventable diseases with parents/guardians.

Physicians and other health care providers at CHEO are committed to providing the most up to date and reliable immunization information in an open and constructive manner to patients, parents/guardians, and the public at large.
