When it comes to vaccines - why are people talking about 'Vaccinated are a threat' ?

Vaccinated people are less healthy, spread diseases or do not take precautions

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:

  • An intuitive cognitive style; accepting ‘gut feeling’ as a better guide to truth than evidence.
  • Ontological confusions; people may struggle to differentiate metaphorical from factual statements, for example taking statements that ‘trees can sense the wind’ or ‘old furniture knows things about the past’ literally.
  • Being receptive to pseudo-profound statements, for example considering a statement such as ‘wholeness quiets infinite phenomena’ to be profound.
  • Susceptibility to causal illusions; believing that one event affects another when in fact there is no causal relationship, for example that your favourite football team won a game because everybody watching it from home was wearing the team jersey.

This theme encapsulates the belief that people who are vaccinated are different and dangerous. Allegations include that vaccinated people are less healthy, spread disease and make< others sick, or behave irresponsibly for example by not taking precautions.

Is there any truth in it?

It can be worrying when other people do not take precautions such as mask wearing to reduce the spread of disease after being vaccinated. Some vaccines, such as the COVID-19 vaccines, also do not completely protect from transmitting the disease, although they reduce the severity of the disease if we get it. We should all do what we can to protect ourselves from diseases, such as taking care of hygiene and being prudent with our contact with others.

What could I say to someone fixed on this belief?

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:

Having set the stage through this (partial) affirmation, we can then proceed to correct the patient’s particular misconception.

Vaccinated people are less likely than unvaccinated ones to spread the disease they are protected from, if only because they are already less likely to get it. Vaccination in itself is a precaution, as we cannot isolate ourselves completely from exposure to diseases.

All groups of people have inconsiderate individuals who take less precautions, so there will be some vaccinated people who behave badly, but there are many more vaccinated people who do adhere to other prevention measures.

Ultimately, we should protect ourselves from the severe consequences of diseases, and vaccines are the best way to do so.
