The Ministry of Health and Social Services (MoHSS) in Namibia intends to embark upon a COVID19 vaccination campaign in the Country. But before deciding which type of COVID19 vaccine to be ordered from the Manufacturers, they first carried out a survey on some countries around the world in order to establish the most preferred vaccine. The findings revealed that: Sixty-eight (68) of them prefer the Pfizer; fifty-two (52) prefer the Moderna; and forty-eight (48) prefer the AstraZeneca. Thirty-six (36) of them prefer Pfizer and AstraZeneca; twenty-two (22) of them prefer Moderna and AstraZeneca; None of the countries prefer AstraZeneca only; 24 prefer Moderna only; 26 prefer Pfizer only; and the remaining 90 countries preferred none of the vaccines.
