If you had bothered to read the article posted by the OP, you would have found this:
When will the vaccine be available?
A limited number of people may get the vaccine this year.
Pfizer and BioNTech say they will have enough safety data by the third week of November to take their vaccine to regulators.
Until it has been approved it will not be possible for countries to begin their vaccination campaigns.
The two companies say they will be able to supply 50 million doses by the end of this year and around 1.3 billion by the end of 2021. Each person needs two doses.
The UK should get 10 million doses by the end of the year, with a further 30 million doses already ordered.
Who would get it?
Not everyone will get the vaccine straight away and countries are each deciding who should be prioritised.
Hospital staff and care home workers will be near the top of every list because of the vulnerable people they work with, as will the elderly who are most at risk of severe disease.
The UK is likely to prioritise older resident in care homes and the people that work there.
But it says
a final decision has not been made, saying it will depend on how well the vaccine works in different age-groups and how the virus is spreading.
People under 50 and with no medical problems are likely to be last in the queue.
