COVID vaccine under new scrutiny after studies reveal possible health risks | 20 Nov 2025 | Two large studies have put a spotlight on potential health risks of the COVID vaccine… Recent research has linked the vaccine to a higher risk of kidney injury as well as certain respiratory infections. A Korean study published in the International Journal of Infectious Diseases looked at how infectious diseases changed during and after the COVID-19 pandemic, as well as the impact of vaccines. In another recent study published in the International Journal of Medical Sciences, COVID-19 vaccination was associated with a higher risk of acute kidney injury and dialysis within one year, although vaccinated people had lower rates of death from all causes [Yeah, right!]. Within 12 months, 15,809 vaccinated people developed acute kidney injury, compared to 11,081 unvaccinated people. A total of 1,513 people received dialysis within a year of vaccination, compared to 697 unvaccinated people.
