The multi-biollion dollar question... given, that as I'm sure you're aware, claims are based on short-term - and no study into long term. My guess is that no study has been done on long-term as it would make the SS account look like the Gates Foundation.
The Vaccine Injury Table (Table) makes it easier for some people to get compensation. The Table lists and explains injuries/conditions that are presumed to be caused by vaccines. It also lists time periods in which the first symptom of these injuries/conditions must occur after receiving the vaccine. If the first symptom of these injuries/conditions occurs within the listed time periods, it is presumed that the vaccine was the cause of the injury or condition unless another cause is found. For example, if you received the tetanus vaccines and had a severe allergic reaction (anaphylaxis) within 4 hours after receiving the vaccine, then it is presumed that the tetanus vaccine caused the injury if no other cause is found.
If your injury/condition is not on the Table or if your injury/condition did not occur within the time period on the Table, you must prove that the vaccine caused the injury/condition. Such proof must be based on medical records or opinion, which may include expert witness testimony.
