Like you rightly said vaccine has been made available for Covid-19, though my country's economy is yet to be fully resuscitated into its former state before the virus started, it is getting better and as you have said looking forward to the brighter side.
It already see the positive effect of the vaccine but due to the people that not taking the vaccine yet, there are still cases reported to our country. Its not full back to normal but most of the people get back to work and the jobless residents have also increase. It's getting better and better but still we need to apply minimum precaution and guidelines to prevent the virus from getting spread rapidly. I guess we'll the fully improvement of the countries by the end of the year. Vaccine also need to give to poor countries they also need to be priority.
The problem is that some countries are not able to provide free vaccines to their people, the government realizes that if everyone is given the vaccine, their immune system is stronger and more susceptible to viruses. for some countries, if someone wants to be vaccinated, of course they have to spend money and some assumptions from the community that the corona virus is able to grow a pharmaceutical business that is able to strangle the lower class population.
