It is said that all the corona virus vaccines we have have exceeded the safety standards of WHO, and they have proved to be very effective. But that doesn’t mean that all vaccines are the same, and provide the same level of protection. Benefit and immune protection profiles are similar, but not standard. This means that some vaccines may be more suitable for someone, or some vaccines may potentially carry a higher risk of success. Therefore, while it is important to have a jab with any vaccine available to you, weighing the relative risk reduction, that is, how much an individual COVID-19 vaccine reduces the risk of infection compared to an uninfected population, is essential. Also comparable are the possibilities of symptomatic disease, severity, transmission, and other safety profiles.
While ongoing clinical studies, comparative evaluations and real-world data on the matter have reported that Modera and Pfizer mRNA vaccines offer a 95% reduction in symptomatic disease, the Janssen vaccine offered a 60% lower risk offered. With the AstraZeneca (Covishield) shot, there is a 70% reduction, which can be increased to more than 80% if the gap between doses is lengthened.
