The United Kingdom's new travel advisory states that passengers who are not vaccinated under "approved programmes in UK, Europe or the US" must self-quarantine for 10 days in the country even if they're fully vaccinated otherwise. This means that even Indians fully vaccinated with Covishield, the Serum Institute of India-produced Oxford/AstraZeneca vaccine, are not exempt and will have to quarantine and get tested at their own expense. Is the UK indulging in vaccine racism?
