Vaccines developed to prevent Covid-19 cases have different efficacy data. Some might think that those with greater effectiveness are better than others. But a comparison based on this data alone is not correct.
Covid vaccines, how effectiveness is calculated and why it is better not to make comparisons
Understanding how the effectiveness of a vaccine in preventing Covid-19 cases is calculated in a population exposed to the risk of contracting the disease can help us understand why. At the origin there is a mathematical formula. Applied on data derived from experiments that for each vaccine occurred in very different times and contexts.
