Iraq has signed a preliminary deal to receive 1.5 million doses of the Pfizer-BioNTech coronavirus vaccine in early 2021, the health ministry said.
The country has been among the hardest-hit in the Middle East, with more than 580,000 reported cases although numbers have dropped dramatically in recent weeks.
Health ministry spokesman Seif al-Badr told state television late Monday that Iraq had "formally signed a preliminary deal with Pfizer... which will arrive in stages early next year".
"Iraq has reserved its share of these vaccines," he said, with troops and the elderly prioritized for vaccinations, AFP reported.
Each person requires two injections of the vaccine so the order will cover just 750,000 of Iraq's 40 million people.
President Barham Saleh has said Iraq aims to provide the jab for free to its citizens.
Badr did not put a price tag on the deal.
Western officials in Iraq told AFP that Washington had been urging Baghdad to choose Pfizer-BioNTech over other options.
Pfizer's vaccine must be stored at -70 degrees Celsius (-94 degrees Fahrenheit), a temperature much lower than standard freezers and which forced the company to develop special containers for transport.
Iraq is one of the hottest countries in the world and has a dilapidated power generation network that results in daily cuts to mains supply.
"The issues of transportation and financial transactions are still being worked out," Badr said, adding that Iraq had the necessary equipment to safely distribute the vaccine.
He said Iraq was still in talks to receive more vaccines through Covax, a worldwide network created to ensure equitable access to Covid-19 vaccines.
Iraq has committed $170 million to be among the first countries to receive the vaccine, according to the World Health Organization.
The country has seen a remarkable reduction in Covid-19 cases and deaths in recent weeks even as testing ramps up.
On Monday, out of more than 35,000 tests, just 1,200 tested positive for Covid-19 cases and 13 people died.
The encouraging numbers have coincided with a lifting of all lockdown measures, and people across the country are wearing masks less and ignoring social distancing.
But Badr insisted the danger had not passed.
"A vaccine is not a magic solution," he told state media.
