ZURICH/GENEVA (Reuters) - The World Health Organization (WHO) does not recommend countries issuing "immunity passports" for those who have recovered from COVID-19, but is looking at prospects of deploying e-vaccination certificates like those it is developing with Estonia.
Estonia and the United Nations health agency in October started a pilot project for a digital vaccine certificate - a "smart yellow card" - for eventual use in interoperable healthcare data tracking and to strengthen the WHO-backed COVAX initiative to boost vaccinations in developing countries.
