Implausible side effects and contaminants (e.g., autism or active viruses)
Some people will reject vaccinations based on unwarranted beliefs. For example, the claim that the body has a ‘natural healing potential’ or that ‘natural’ is always better. This may lead people to believe that suffering a ‘natural’ disease in order to achieve subsequent immunity is preferable to being vaccinated, which is the exact opposite of the actual risks.
Many adherents of ‘alternative medicine’ hold unwarranted beliefs and are sceptical of vaccinations.
Research has shown that these unwarranted beliefs are particularly shaped by ‘cognitive variables’, a psychological term which describes the ways in which people process information.
It is these cognitive variables that separate unwarranted beliefs from conspiracist beliefs, which is primarily influenced by perceived threat and emotional variables.
These cognitive variables include:
This theme encapsulates beliefs that vaccinations cause severe harm or are ineffective. Critically, these arguments are based on implausible beliefs and perceived associations that are not backed up by scientific evidence.
It is normal to have questions and doubts about medical treatments and how they might affect us. The world can sometimes feel like a dangerous place, and we don’t fully know why some conditions occur. It is understandable to want to know what caused a problem so we can try to avoid it or solve it.
Dialogue between patients and healthcare professionals is most productive if it is guided by empathy, and an opportunity for the patient to affirm the reasons underlying their attitudes and to express understanding for that. That’s why it is important to understand the attitude roots behind people’s overt opinions. To affirm a person’s underlying attitude root does not mean we need to agree with the specifics of their argument. For example, we can acknowledge that:

Fear and uncertainty can lead us to see connections that do not exist.
Those with vested interests in finding false links often go to great lengths to publicise false information. For example, in 1998 Andrew Wakefield, who was paid by personal injury lawyers, published an article that falsely claimed a link between MMR and autism. The article was retracted after his scientific misconduct was revealed, and extensive research has found that vaccines do not cause autism.
We need to distinguish between events that simply occur at random close together, and those that are actually linked.
Not everything that happens just after we have a vaccination is caused by the vaccine.
Sometimes unrelated medical conditions occur close to a vaccination, but so do other accidents. If we had an accident in the hospital carpark after getting a vaccine, that would be tragic, but it cannot be blamed on the vaccine.
