I agree that vaccination, or rather problem vaccination, exists in countries with a very large population, where there are hundreds or more millions of people. Or where the population is spread evenly and over a large area. In such countries, the vaccination process is very extended in time and territory. But for countries with indicators of even several tens of millions, and more or less developed infrastructure, this is no longer such a global problem. For example, in Ukraine, over the past 2 months, we have made a strong breakthrough in vaccination, and already 13% have been vaccinated once, almost 9% completely. In the largest cities of the country (and this is about 80% of the country's population), a lot of vaccination centers have been opened, where there are 4 types of vaccines, and a free registration for vaccination. For example, here is a link to a single Ukrainian resource, in this case for the city of Kiev (https://helsi.me/clinic/926a56de-cc9f-4d32-a393-021cc1b3c194/doctors?mode=table), a simple example is an online platform and a chart (for the record) at one of the vaccination centers. The platform is the same for the whole of Ukraine, any citizen, in any accessible locality, can freely and free of charge sign up and receive vaccinations.
