It is not clear when exactly all 50 hubs will receive vaccine doses, as they are starting to administer the vaccines at different times.
However, deliveries of the Pfizer vaccine are expected throughout the week.
The bulk of vaccinations in the UK are expected to take place in early 2021, with 40 million doses of the Pfizer vaccine secured by the UK Government in total.
NHS Providers deputy chief executive Saffron Cordery said she expected up to four million doses of the Pfizer vaccine will be available in the UK by the end of December.
Other vaccines, such as the Oxford/AstraZeneca vaccine, are still awaiting approval for use in the UK.
