Abstract
Aim: We conducted the current analysis to determine the potential role of measles vaccination in the context of the spread of COVID-19.
Methods: Data were extracted from the world health organization’s (WHO) Global Health Observatory data repository about the measles immunization coverage estimates and correlated to overall morbidity and mortality for COVID-19 among different countries. Data were statistically analyzed to calculate the Spearman rank correlation coefficient (rho).
Result: There was no significant correlation between the measles vaccine coverage (%) and both of new cases per one million populations (rho= 0.21; p-value= 0.052) and deaths per one million populations (rho= 0.21; p-value< 0.080) (Figure 1; Figure 2). On further analysis of the effect of the first reported year of vaccination policy, there was no significant correlation with both total cases per one million populations (rho= 0.10; p-value= 0.361) and deaths per one million populations (rho= 0.17; p-value= 0.156).
Conclusion: Claims regarding the possible protective effect of measles vaccination seem to be doubtful.
