This protein (spike) is nasty – it is sometimes called a ‘pathogenic protein’ – and is recognised as the cause of many of the terrible diseases associated with COVID-19. Logically you would inactivate or at least try to attenuate this nasty spike protein and develop a vaccine around the attenuated virus. But that is not what has been done. These ‘vaccines’ do not contain the offending virus at all, but rather the gene sequence that causes the production of the nasty spike protein in the body….

A recent study seems to confirm that the vaccine spike remains for many months in the body, thus having time to cause various damages. Here is just one of many examples.
