‘Covid-19 has already cost more than 3.3 million lives, and we are on track for the second year of this pandemic to be far more deadly than the first,’ Adhanom Ghebreyesus tweeted.

The only way to save lives is a combination of vaccination with public health measures, he said.

He considered that one of the major challenges is precisely the availability of Covid-19 vaccines in the poorest countries.

The WHO director general suggested that developed countries share the vaccines they have planned for children with less developed nations.

He recalled his warning about ‘vaccine nationalism,’ and now some rich countries, which purchased most of the vaccine supply, are administering it to low-risk groups. Adhanom proposed sharing technologies and knowledge to boost the production of Covid-19 vaccines.
