President Uhuru Kenyatta has secured 817,000 doses of Oxford-AstraZeneca Covid-19 vaccines during his trip to London.
In a statement on Wednesday, the UK government said the vaccines will be shipped to in the coming days.
The announcement came as Prime Minister Boris Johnson meets Uhuru in Britain.
The nine million shots are the first tranche of the UK's commitment to share 100 million vaccine doses internationally by next June.
Last week, US president also said 1.7 million doses of Pfizer vaccine donated by the US are expected to arrive in the country in August.
US President Joe Biden pledged 500 million doses of the BioNTech-Pfizer coronavirus vaccine to developing nations just before the G7 Summit.
The 500 million doses have been donated to the Covax facility, which will share the vaccines in partnership with the African Union.
“The first 60 million doses will be deployed in August and what I can tell you is that Africa will receive a significant portion because we recognise the coverage is still low even with the doses they have procured,” Gayle Smith said.
