Medics and other healthcare frontline workers will start receiving the COVID-19 jab on Friday at the Kenyatta National Hospital.
This is after President Uhuru Kenyatta flagged off of the vaccines at Kitengela storage facility.
Health Cabinet Secretary Mutahi Kagwe said the process is being rolled out in all the 47 counties, starting with frontline workers, teachers, security personnel and those over 58 years.
The country received the first batch of 1.02 million doses under the Vaccines Global Access (COVAX) program on Tuesday evening aboard a Qatar Airways flight QR1341.
The consignment was received by top government officials led by Kagwe his Transport counterpart James Macharia and Margaret Kobia (Public Service).
Kenya now joins other countries in the globe who have began vaccinating their citizens against the virus.
Kagwe emphasized on the need to adhere to the Ministry of Health guidelines to help curb the spread of the virus saying that having a vaccine does not mean we have a cure.
He regretted the high rate at which the virus was spreading noting that the positivity rate has moved from 2.8 per cent to 9 per cent since January this year.
Between now and June 30th government is targeting to vaccinate 1.25 million Kenyans in the first phase and 9.6 million in the second phase.
The country is also planning to import 24 million doses vaccine which the World Health Organization (WHO) should cover at least a third of the population.
