Kenya will receive about 150,000 doses of the AstraZeneca Covid-19 vaccines from neighbouring countries.
Health Cabinet Secretary Mutahi Kagwi said the government expects the doses from countries like Congo before they expire this June.
Currently, there are about 100,000 doses left from the 1.12 million doses which were acquired in March this year.
"We are still vaccinating, but what I can tell you is that we are at the tip, and we need more vaccines like yesterday," CS Kagwe said during an interview with CNN's Larry Madowo.
"It is a fact the doses the government had acquired to be administered for phase one were now on the verge of running out as close to one million had so far been vaccinated," he continued.
CS Kagwe also called on people who received the first dose of the vaccine to be calm assuring them that the second dose will be administered soon.
"Those who have received the first dose should not panic as having the first dose in itself according to medical experts offered protection of up to 70 per cent. So far there have been no reports of any adverse effects for those who have not been given a second dose," he said.
"We have information the United States of America is willing to give up some 60 million doses to other countries. Kenya only required about 1 million doses to vaccinate those who had received the first dose."
