Vaccines: If it had been more than 10 years since your last tetanus vaccine, there is more tenderness at the vaccine site. Any vaccine elicits an immune response, which can make u feel tired, especially in the extremities where u received the vaccines. Try cool rags on injection sites ; and, use your arms as much as possible to increase circulation.
