Russian President Vladimir Putin is trying to reassure people that his country is on track to get its first measles vaccine by the end of the year.
Putin said Sunday that the country had the vaccine for measles and that it is ready to start mass vaccination.
But, he warned, there are still uncertainties about the final outcome of the trial.
The government hopes to receive the vaccine in mid-December, Putin said.
The trials are being conducted in collaboration with the United States.
The trial is scheduled to last four to six weeks.
The first trial started in December.
Russian authorities had hoped to have the vaccine ready by mid-January.
Putin had said earlier this month that the vaccine would be ready by early January.
The vaccine is manufactured by Moscow-based AstraZeneca and is manufactured in the Russian city of Novosibirsk.
Putin has said he hopes the vaccine will be ready for the Russian population by March 1.
The Russian government is not accepting any exemptions for the trial and has not ordered any restrictions on vaccination, according to the Federal Migration Service.
Russia’s health ministry said Sunday the trial is proceeding at a “very high speed.”
The trial will start on Dec. 14 and finish on March 1, according a statement from the ministry.
The ministry said that it hopes to complete all trials in the coming months.
Health ministry officials have said that all people over the age of 18 who will be vaccinated will be given a vaccination voucher that will be used for other purposes, such as the purchase of a new cellphone, television, or other personal items.
