Vaccination against Covid-19 have started in several parts of the world. However, access to vaccines, especially by poor and middle income countries, has been a major issue. Therefore, it's not the right time to travel.

His comments come at a time when several countries are considering vaccine passports for international travel.
The WHO official said that if access to vaccine is not equal then inequity and unfairness can be further branded into the system.
While vaccination drives against Covid-19 have started in several parts of the world, access to vaccines, especially by poor and middle income countries, has been a major issue.

Kate O'Brien, Director for Immunization, Vaccines and Biologicals at WHO, said that the UN agency is supportive of electronic vaccination certificates for a number of reasons, not the least of which are the efficiencies of time, the accuracy of the information, the link to the products that have been received.
