I am sorry but no you cannot sue the NHS The Hep B vaccine can cause some of these side effects short term. They are common side effects and to be expected. The vaccine does not cause any of these long term side effects. The clinic merely administered the vaccine. There is no clinical or medical negligence. I would look at other causes for your issues.

The vaccine is supposed to produce an immune response so that you will be immune to the virus. That is what it does. It does not produce long term side effects as a result.
