Abstract
A recent finding that the two-dose vaccination for the Covid-19 virus leads to a rapid loss of protection in many patients within 6 months. Thus the need for a 3rd injection has been found to be mandatory for continuing protection, as well as to highlight the need to monitor immune compromised patients and those with comorbidities particularly in indigenous populations where co-morbidities may be present preventing an adequate response to the initial vaccination. This has also highlighted the problem of lack of vaccines in the less developed parts of the world that requires urgent attention, as this is where new variants arise. The virus must be contained in these countries before we run out of letters in the Greek alphabet. Key words: Covid 19, virus, vaccines, 3rd injection, immunity, mutations, WHO
