evidence: A study from researchers at the University of Melbourne[1] became the basis of claims on social media that the Pfizer COVID-19 vaccine damaged children’s immune response against other diseases. One example of such a claim can be seen in this article by the Florida Standard. It claimed that the study "shows weakened immune response in kids injected with Pfizer’s COVID-19 shot". The website also added that "this caution perhaps seems like a bizarre afterthought, since children around the world are injected with mRNA COVID-19 shots as a matter of routine". This statement implied that health authorities, vaccine manufacturers and researchers alike had overlooked a risk to children’s safety. Another example of this claim comes from writer Alex Berenson, who claimed on his Substack page that "The mRNA Covid jabs damage immune responses to other viruses in children" and evoked a "long-term immune deficiency".
