Travel has always at it’s most fundamental level been about freedom. Over the years there have been necessary limitations on that freedom, for security needs or the purposes of public health for example, and by and large they have been reasonable and acceptable, but this newly proposed ‘vaccine passport’ for Covid19 is a step too far. It places unparalleled restrictions on our freedom to travel with no clear clinical justification, is immoral, unethical and even illegal in many countries, and should never be imposed on any traveller anywhere.
