I'm always hearing a lot of them saying about the pandemic as a conspiracy theory. No to mention how this pandemic gave difficulty to those people who have experienced it personally and to those who have lost their loved ones. But as the vaccines are coming its trials and there were few who have said to be almost effective 100%, it is not for free so as usual we will think of it as a business. Business or not, buy the vaccine if you want to avoid the virus.
I will not say categorically, but it seems to be incredibly difficult and almost impossible to create a vaccine with one hundred percent effectiveness, especially in the case of coronavirus. About the free of charge of the vaccine itself. The vaccine cannot be free in principle, because you have to spend money on development and production, and no one will deal with such issues for free. Therefore, everything depends on the position of state authorities and how much they are willing to pay for such expenses. In theory, the widespread introduction of the vaccine will protect against unnecessary costs in health care and will allow for less losses in the economy.
