Kenya's President Uhuru Kenyatta has ordered all teachers to have a Covid-19 vaccine irrespective of their age.
The country has been vaccinating school managers and those aged above 50, elderly citizens and front-line workers.
More than 500,000 people have had the AstraZeneca jab out of the more than one million doses delivered to the country.
All teachers and non-teaching staff in schools should have the jab before schools reopen on 10 May, the president said.
According to the head of Kenya's Teachers Service Commission, Nancy Macharia, 15 primary teachers, three deputy headteachers and eight headteachers have died of Covid-19 during the pandemic.
