Post Vaccination Syndrome is a cluster of persistent symptoms that can develop after vaccination, often resembling those seen in Long COVID or other post-viral syndromes. Symptoms may include fatigue, brain fog, nerve pain, dizziness, and rapid heart rate. As awareness grows, more patients are being evaluated and treated in specialty clinics, and research into the condition continues to expand.
