I sympathise. If we are going to use vaccine status as part of managing travel we do need a way to standardise these things to treat people fairly. It would be great if everyone could accept WHO approved as a baseline, but such are the problems about political influence over WHO a lot of countries haven't agreed to it. In fact even the covax program hasn't agreed to use the WHO list.So I live in South Asia where the predominant vaccine is sinopharm (Chinese diplomacy/influence). My sister needs to travel to Germany for work next month and she’s been asked to take not just one but two doses of Pfizer by the German embassy.
Repeat; that’s two doses of sinopharm and two doses of Pfizer within the span of 7 months.
I've also had to have a two dose course of Pfizer (not just a booster), despite being fully vaxxed with Novavax as part of a clinical trial last year. Novavax passed its efficacy trial but couldn't ramp up production as planned and as such is still not approved by the MHRA, CDC or EMA. The UK and US recognise the trialists as vaccinated but Europe and most private companies don't.
There's a suggestion now that the definition of fully vaxxed will be three doses, which might be good for me (I've had 4!) if they accept the trial vaccine as part of it - but a guinea pig nightmare if they don't. A nightmare for those on the unapproved vaccine list trying to move as well. And that's before I get onto the waste of vaccine involved.
Meanwhile, I'll just assume it was worth it and made me invincible.
