Brief Summary

Mortality rates caused by SARS CoV-2 differ between countries and this difference might be explained by several reasons. Childhood vaccination rate is thought to be one of them. Therefore present study aimed to examine the possible relationship between DTaP (diphtheria, tetanus, pertussis) and measles vaccination rates of Organization for Economic Co-operation and Development (OECD) countries and case fatality rate (CFR) caused by SARS CoV-2.
