For people travelling abroad for education, employment and India’s contingent for Tokyo Olympics, the central government on Monday issued SOPs for COVID-19 vaccination, and said the CoWIN certificates will be linked to passports of such travellers. 

Such travellers can also take their second dose of vaccine after 28 days, the Centre said. 

The Union Ministry of Health and Family Welfare said that no other qualifying entries required in vaccination certificates, and added that mention of vaccine-type as ‘Covishield’ is sufficient.
