Furthermore, given some government's reaction, was wondering if the vaccine will be enforced through the passports.
This is not an opinion it is fact stated by the ministry doctors. Passports will be used to verify "proper" vaccination status. "Proper" will evolve over time as new variants emerge and as we know more about things such as vaccine durability.
If I had to guess, I would bet that after the 5-11yo get vaccinated, depending on the rate of success they will slowly do the third doses in descending age groups and spring will roll around, cases will come down and next summer will be fine. Delivery of new vaccines won't arrive before. They won't make status dependant on something we don't have in our hands.
A big part of the population was vaccinated less than 6 months ago, the young is in full swing and third doses to the elderly is progressing. We will be fine. We will see large growth in cases, moderate growth in severe case.
The unvaccinated will remain restricted, by their own decision and/or their inability to deal with facts.
