The question of choice hasnt been much of an issue in the United States, where the two vaccines in use  Pfizer and Moderna  are basically equivalent, both Made in USA, both relying on the same technology and producing the same results in clinical trials.

In April, hair salons, barbers, gyms and nonessential shops may open. But one just gives your immune system a better foundation.Pfizer, incidentally, is a U.S.-based pharmaceutical giant, but the vaccine was developed by a German Turkish couple running a small cutting-edge company called BioNTech. The study showed that just a single dose of the Pfizer vaccine had reduced the number of people developing symptomatic Covid-19 infection by 85 per cent.
