At least your colleagues the engineers are making an effort by building potholes for roads. You also could try to create a vaccine even if it will cause diarrhea. Or are we going to continue to look to vaccines made elsewhere?”
This is a call to Malawian scientists to try to make their own vaccine instead of just discussing vaccines made elsewhere. This is a cry for homemade solutions instead of just and always relying on solutions from elsewhere. Reference to engineers building potholes for roads, is a sarcastic reference to poor road construction in Malawi.
