The Government dashboard says that 15,062,189 people nationally had received a first vaccine dose as of February 13, with 537,715 having a second dose up to this date.
The agency said 38,292,270 people had received one or more doses while 14,077,440 people have received the second dose as of Sunday. Mexico and Argentina have an agreement with AstraZeneca to produce the vaccine for eventual distribution of 250 million doses in Latin America, with financial support from the foundation of Mexican billionaire Carlos Slim.
The Ontario government reported that all long-term care residents across the province have been given an opportunity for their first dose of COVID-19 vaccine.
Hillier said the province had to adjust its vaccination plan because of an unexpected reduction in supply of vaccines from the federal government, but the disruption in deliveries has not stopped the rollout or the province's commitment to vaccinating high risk populations and people who care for them.
Only two COVID-19 vaccines, the Pfizer-BioNTech and Moderna vaccines produced in Europe, are approved for use in Canada and both companies have come up short in their recent shipments to the country.
So far the vaccination programme has been aimed at the top four priority groups, including NHS frontline staff, care home residents and workers, over-70s, and people deemed clinically extremely vulnerable.
While the 15 million figure was a key indicator of the vaccination target Mr Johnson set on 4 January, it is not yet known whether the aim to offer the first jab to everyone in all United Kingdom nations from the four most vulnerable groups has been met - despite Wales's First Minister Mark Drakeford saying the target had been met there on Friday.
"The vaccine is our route to freedom - we will beat this virus jab by jab".
"We do need to be very careful in how we proceed", Raab said on Sky.
NHS chief executive Sir Simon Stevens said: "Hitting this milestone.is a remarkable shared achievement".
Raab, the foreign secretary, said it was "the first milestone towards the wider plan to get every adult in the country offered a first dose by the autumn".
The target was set back on January 4 when Mr Johnson said that by mid-February it is expected that the first vaccine dose will have been offered to everyone in the four top priority groups identified by the JCVI.
"These vaccines are safe, they're effective against Covid, they'll protect you, they'll protect your loved ones, and of course they'll help get society back to normal again", he said.
"All restrictions remaining after March 8 should be proportionate to the ever-increasing number of people we have protected".
