The Pfizer and BioNTech vaccine, which could prevent more than 90 percent of people from contracting Covid-19, is one of 11 vaccines currently in the final stages of testing.
Health officials have said the program will offer all vaccines that work; even if not all are equally effective.
A government source said: “We will go with what we have; we save most lives doing it that way, following what’s available here and now. “
Officials emphasized that different types of vaccines may have different effectiveness in particular age groups or other risk profiles.
Under NHS plans, vaccination centers, generally run by GPs, have been told they will have to be able to administer at least 1,000 injections per week.
Because Pfizer jab must be stored at a temperature of minus 70 ° C, the supplies will be delivered from Belgium frozen in boxes and can only be kept in standard refrigerators for several days.
So far the largest vaccination program delivered in the UK was 15 million flu shots last year. This winter, the NHS aims to immunize 30 million people.
