Vaccination had a modest effect on time off work and had no effect on hospital admissions or complication rates. Inactivated vaccines caused local harms and an estimated 1.6 additional cases of Guillain-Barré Syndrome per million vaccinations. The harms evidence base is limited.
So, to repeat, NO reduction in complications, NO reduction is deaths, NO reduction in hospitalisations, a small chance of less time off work but an increased risk of permanent neurological damage. Let me roll up my sleeve – NOT!
