Example of how vaccine injury is misrepresented in medical publications: https://onlinelibrary.wiley.com/doi/10.1002/emp2.13250 This case concerns a child who developed transient synovitis the day after a triple vaccination (PPSV 23, influenza, and DTaP). On examination in hospital, the PCR COVID-19 test was positive (presumably false positive). The child had no COVID-19 symptoms. The title of the case report is "A toddler with transient synovitis and COVID-19 infection", but the title should actually be as follows:
