Don't worry, soon they will all get the vaccine, some countries are even donating vaccine to the poor countries so it's not really a problem. We were able to survive before the vaccine, now that it's here and the only problem is only the distribution and production, it should not be a big problem anymore.
The so called "donations" usually involve very small quantities and they are not sufficient to vaccinate even the highest priority population group. These deliveries normally include only 10,000 or 20,000 doses of the vaccine.
