Meanwhile, TSC CEO Nancy Macharia said all teachers can now access the vaccine.
This is after a ministry meeting with President Uhuru Kenyatta, who approved the move.
Initially, it was teachers above the age of 50 who were prioritised during the first phase of vaccination.
Macharia urged all tutors to take advantage of the new directive to get the jab as schools are set to open in May.
Macharia announced that at least 15 primary school teachers have died since the Covid-19 pandemic struck the country in March 2020.
"We have lost three deputy head teachers and eight head teachers to the pandemic," she said.
Macharia said going forward, the commission has come up with measures to protect all teachers from the virus.
"First we instructed our medical health insurance provider to cover all teachers against Covid-related ailments which they have since complied with," Macharia said.
