COVID-19 flu has been the worst pandemic on earth in more than a century and has thus far claimed more than six million lives worldwide. As of 19th March 2022, there were 57 major countries where one million or more COVID-19cases were registered, and the deaths reported therein constituted 92.3% of the total deaths worldwide. The high mortality rate is associated with comorbid conditions of the infected. Obesity, diabetes, cardiovascular diseases, high blood pressure, chronic obstructive pulmonary diseases, tuberculosis, and a higher percentage of the aged population (more than 65y) were identified as major morbidity conditions among others. Mycobacterium sensitized healthy people were found to resist the disease more efficiently. Prior vaccination with human influenza virus vaccines had considerable protective effects against catching or manifesting severity in COVID-19 flu. Timely vaccination with an approved vaccine against SARS-CoV-2 was considered immensely protective from the disease. All countries should therefore adopt policy measures that ensure adequate vaccination among their population.
