Nothing can be done, because the vaccine manufacturing units are working with limited capacity. Even here in India, we are facing a severe shortage of the vaccine doses, despite being the manufacturing hub of the AstraZeneca vaccine. Now the government has even given permission to import vaccines from abroad, which would have been unthinkable a few months back. If this is the case in a country which manufactures huge amounts of the vaccine, you can imagine the condition of the other countries.
In India, the number of new infections had decreased by around 95% by January-February 2021. A lot of people thought that now it is safe and therefore went out for vacations. And many of these people who went for outings in March returned home infected with the Coronavirus. I personally know the story of one of my colleague's cousin who died of COVID 19. He was only 30 years old. He went out for a small tour with his family and got infected. The entire family was infected. The other family members recovered, but he died after 3 weeks of illness. I am located in the Southern part of India and here the infections are yet to peak. But when I talk to my colleagues in Northern India, almost every one is either infected for COVID 19, or taking care of someone who is suffering from it. The situation changed here very rapidly.
You need to make a choice. Either wait for a few months, to breathe fresh air, or to risk infection now.
