Sounds like an organized chaos. I supposed there weren't any distancing. Probably catch the bloody covid 19 waiting for your turn. I like to avoid crowds especially old gits like me lol. I'l wait til the crowds get organized then wait 1 meter distance, if anyone comes within that distance I will kindly tell them to back off.
You should not wait too long. There is a limited number of vaccines and the quantities expected in the future will probably be greatly reduced as India hordes them. The AstraZeneca vaccines that are being administered come from the COVAX initiative that purchased them from the Serum Institute of India. COVAX, which is critical for poorer countries, relies on AstraZeneca shots made by the Serum Institute of India, the world's biggest maker of vaccines. It was already around 100 million doses short of where it had planned to be when India halted exports a month ago amid a surge in infections there. https://news.yahoo.com/covid-fight-could-return-square-145114623.html
AZ 6o% effective on India variant - 2 doses, just 33% on one dose. India variant is also hitting kids harder.
