The pandemic of COVID-19 has been curbed in many countries due to the arrival of a number of efficacious vaccines. Yet, there are many unknowns in the evolving COVID-19 vaccine story, although we now see the emerging true situation in a better light, with reports of their efficacy ranging from 55% to 95 % depending on the vaccine strain. However, this situation is compounded by the reported vagaries of the increasing number of brand-name vaccines, manufactured on both the new and old vaccine platforms. These include their adverse effects, the emergence of possible vaccine-resistant viral variants (e.g. the current delta and lambda strains of SRAS-CoV-2), the efficacy of mixed mode vaccinations, necessity of booster doses and their immunological correlates, as well as reasons for vaccine resistance by a small proportion of the populace. This presentation will provide the details of the foregoing, as well as an outline of the basic mechanisms of vaccines, with a particular emphasis on those available in Sri Lanka.
