I'm not sure why they felt the need to add "attempt" in the headline when he was clearly successful in getting immunity.

If you're in China: some places are offering vaccination with the new inhalation-type vaccine. Some studies have shown it to be more effective at preventing infection compared to both injected adenovirus vaccines and mRNA vaccines. So get in queue to receive that. Otherwise, stock up on food for about a month or so, stay at home and wait for this wave to pass.
