Technicaly unknown. Vaccine was developed, goverments bought and awaiting for cargos. Nobody is putting dispute like on aliexpress for cheap quality or fake one. Citizens will get their needle and if it will not work then the societies will collapse. At the moment roads are closed to leave the cities and to get in if you are from another region. So depression will grow, more companies closed, no work, no income, no real social life not fb or etc. only full control - when to go outside, when for groceries and there will be no point to listen for some oldies while you are drunk on youtube like "The World Is Mine".
