(But I’m hearing the return conditions for Chinese participants would be very onerous, so I’m not sure a lot of them will come physically.) 2 additional shots in february doesn't sound exciting either, when there is likely very little knowledge about the impact of doing that after you had received 2 other vaccine shots some months before. But the fact that such shots would invalidate prior shots with a chinese permitted vaccine does put the icing on the cake. Where did you hear this info ? Cheers Toerless
