Covaxin is still not approved by WHO as it keeps delaying publishing its data of clinical trials. Such delay is causing problems for International travellers as they must get quarantine once they get on international grounds. Countries like the UK are very strict about the traveling protocol are those who have been vaccinated by the WHO-approved vaccine are exempted from 10-day quarantine. The government when asked about the cause of delay in vaccine approval ducked the question. Now even Chinese vaccine has been approved by WHO, the Indian vaccine is yet to receive the EUL from WHO. The people travelling overseas are facing different problems due to the vaccine not being approved by WHO.
