If so, are they no confident with their vaccine?

you are brainwashed by mainstream media, regardless of the brand vaccines are not 100% effective, and effectiveness drops significantly to 39% for Delta variant.  You are not bulletproof after you are fully vaccinated. Israel had 8k-10k new cases per day after majority of population was fully vaccinated, among these cases large number are breakthrough cases, Israel is only using Pfizer and Moderna vaccines. After 82% of population has been fully vaccinated, daily cases in Spore jumped 10 folds, 3.5k new cases per day, mostly breakthrough cases. Vaccine is a false hope for garment to reopen the economy...even after you are fully vaccinated, you will still get infected. So vaccine is not a silver bullet, that is why we are told to live with Covid for the coming years after majority of us are fully vaccinated.
