Covid-19 vaccination is now underway in more than 50 countries, said Tedros, yet all but two of them are high- or upper-middle income countries.
"We must work together as one global family to ensure the urgent and equitable rollout of vaccines," he said.
The WHO chief also stressed that vaccines complement rather than replace fundamental public health measures that individuals, communities and governments must take to stop the spread of Covid-19, which is especially important in the face of rapidly-spreading variants.
The total number of global coronavirus cases has topped 97.4 million, while the deaths have surged to more than 2.08 million, according to the Johns Hopkins University.
In its latest update on Friday morning, the University's Center for Systems Science and Engineering (CSSE) revealed that the current global caseload and death toll stood at 97,460,188 and 2,088,392, respectively.
The US is the worst-hit country with the world's highest number of cases and deaths at 24,619,597 and 409,877, respectively, according to the CSSE.
