Belief is comforting. Many prefer to focus on established findings and accepted facts as they emerge. We know that the vaccine does not prevent infection or transmission. Its advantage lies in its effect in reducing but not always preventing severe symptoms and death in vulnerable people. https://www.gov.uk/government/publications/covid-19-vaccine-....

Both believers and non-believers tend to be immune - to any findings that run counter to their belief systems. Instead of objectively weighing up pros and cons they get rather heated and adopt binary thinking along pro- and anti-vaccination lines with some indulging in the same trap themselves.
