The National Vaccine Institute issued this explanation: "Long Covid-19, or Post Covid-19 condition, [is] a condition that can occur after recovering from Covid-19, but it is not linked to Covid-19 vaccination. Meanwhile, according to the World Health Organization, the causes of Long Covid-19 and why individuals are affected differently are still unclear". In summary, this means that the NVI acknowledges they don't know the causes of long Covid, but they know it is not the vaccines. The m-RNA gene modifying vaccines cause the body to manufacture spike protein. We know vaccination causes and exacerbates existing cancer, heart disease, and a host of other problems -- why not simply acknowledge the truth?
