I haven't heard or read anything that negates the liability of the companies manufacturing these new vaccines. My understanding is that the phase 3 trials for these vaccines were composed of many many more trial participants (all of which fit the specific trial criteria relating to age, comorbidities, ethnicity, and etc) than have been used historically for these kinds products. Hence, much more data on efficacy, side effects, and etc. before release for use in the population. However, the results of their use in the general population ( with all their comorbidities, age variance, medications, ethnicities, and etc.) will most likely not be realized until we are several months down the road.
