Though the researchers acknowledge all the limitations of the study, which is published in the journal Drug Safety, many of the limitations are so critical that they defeat the very purpose of the study. Given the limitations of the study one can “certainly say that the study can’t be used to draw the conclusions it does,” Dr. Menon says in an email. Some of the AESIs in question could have been a consequence of an initial SARS-CoV-2 infection and not the vaccination,” says Dr. Menon. “ They failed to provide substantial evidence on the causal association of some of the serious adverse events like Guillain-Barre syndrome (GBS). And without a comparator non-vaccinated group being asked the same questions, this exercise cannot be really trusted,” says Dr. Menon.
