If the white man was able to come up with vaccinations, he should now have found a vaccination against AIDS; he would now have found a vaccination against tuberculosis; he would now have found a vaccination against malaria; he would now have found a vaccination against cancer.
Kama mzungu anaweza kuja na chanjo, basi angeshagundua chanjo ya UKIMWI; angeshagundua chanzo cha kifua kikuu; na sasa hivi angeshajua chanjo ya malaria; angeshapata chanjo ya kansa.
