Covid is surging in the world’s most vaccinated country. Why?

that's what worries me the most with the medical passport that soon will be required everywhere just to go see a concert : now that it's there, it's never going to stop, it can only expand.

not only because the virus is very likely to follow the same path as the flu, and so people will need yearly vaccination with mediocre results, but also because politics will use this as a hammer and see nails everywhere.

On a sidenote, a 100€ / year vaccine every year, for 6 billions people, enforced by laws... sounds like a dream business model...

It's a country of many islands and a population of 100k. They hit a few hundred cases a day for a few days. If some little pocket of people isn't vaccinated and everyone went to a sporting/music/religious/whatever event it could have set it off. There is a good chance it's totally random.

A majority of the vaccine doses used in Seychelles is the Sinopharm. It uses a human adenovirus as its viral vector. One aspect that was mentioned early last year in Derek Lowe's roundup is that most Asians have existing antibodies against this adenovirus type (for Indians, I believe the figure is around 80%). That may be why this vaccine may not be adequately effective in certain populations.
