Easy to say that it will be over any day but I don't think that it will be difficult, remember that they are still improving the vaccines to the peak levels, the next problem that every government should tackle after the vaccines is the logistics and storage of the vaccines. In my experience considering I am a homebody, I enjoy this lockdown in my country but the academic responsibility is getting annoying.
The vaccine supply has hit roadblocks in most of the countries. Here in India, two vaccines have been approved by the government but both are facing supply issues. First one is the vaccine from AstraZeneca, which is being manufactured by Serum Institute of India (SII). The production has been scaled down due to the shortage of raw materials. The second approved vaccine is CoVaxin from Bharat Biotech. This is a relatively inexperienced company, and they are also facing issues in ramping up the production.
And the Indian government has so far refused to approve Sputnik V and Pfizer vaccines. The first one is not being approved (although the application was made two months ago), due to pressure form the US government. Pfizer vaccine is not being approved due to some bureaucratic hurdle.
