Coronavirus (1466) Knowledge, Attitudes, Practices and Vaccination Hesitancy in Tanzania (2)

[Re: ]


If this study asked a good number of questions, three are missing: “Do you think you are at risk of being infected by the coronavirus?”, “Do you think you are at risk of being sick with COVID-19?”, and “Do you know who is at risk of severe forms of COVID-19?” When considering to get vaccinated, anybody evaluates his or her risk/benefit balance. For COVID-19 vaccination, the potential benefits are avoiding the infection, avoiding the disease, and avoiding severe disease and death. If one thinks that the vaccine causes some side effects and that he or she is not at risk for the disease, the risk/benefit balance will make him or her refuse the vaccine.

In the opposite, if one thinks he or she could be severely sick, the risk/benefit balance is likely to make him or her accept the vaccine.

Different studies have shown that in sub-Sahara Africa, COVID-19 is an “invisible epidemic,” including one we conducted. If we want to increase vaccine uptake, we should study why the pandemic is invisible and how to communicate to make it visible. I published an article on this issue: Public Perceptions, More Than Misinformation, Explain Poor Adherence to Proven COVID-19 Control Measures <>.
