Health inequality in COVID-19 vaccination coverage

According to the latest report of World Health
Organization, which was published on November 8,
2021, more than 249,743,428 people were infected
with COVID-19 and 5,047,652 people died from this
disease worldwide. Furthermore, more than seven
billion doses of vaccine have been used against the
COVID-19 pandemic across the world (1). COVID-19
can take two forms including the asymptomatic and
symptomatic forms and may cause a wide and varied
range of symptoms (2-6). One of the most serious and
current human rights is to have access to diagnostic,
treatment and vaccination facilities against COVID-19,
especially in the poor areas and low-income countries.
In addition, vaccination is regarded to be a very
important primary preventive measure since it causes a
significant reduction in the COVID-19 development,
decreases its morbidity, and reduces its mortality rates
