A new meta-analysis study examining the results from Covid vaccine trials suggests a worrying possibility: that mRNA Covid vaccines, despite protecting against Covid, could reduce the immune system's overall ability to fight infections. On the other hand, the study’s findings also suggest the adenovirus Covid vaccines could have the opposite effect. To many this will sound far-fetched, or even the stuff of conspiracy theory, but University of Southern Denmark’s Professor Christine Stabell-Benn, who led the research, explains to HBI that epidemiologists have known for decades that vaccines can have such ‘nonspecific’ effects and emphasises that regulatory frameworks are in dire need of being updated to reflect this.
