A team of vaccinators from the armed forces was invited to staff the Royal Highland Centre after NHS Lothian put the finishing touches in place and launched it on Wednesday.
Over the last two days, around 1,800 people have been given their first dose of protection against the virus.
The armed forces will provide around 20 vaccinators for up to two weeks, while more training and induction takes place, before the NHS teams switch back.
The mass vaccination centre, the third in Lothian, will be capable of vaccinating around 900 people every day, seven days a week.
