Vaccines have nothing in common with homeopathy.

Vaccines are a preventive measure that expose your immune system to small amount of pathogens, their toxins or small parts of their genetic code (mRNA vaccines) to build up immunity and prevent or lessen future infections. Their effects are proven in multiple studies and meta studies.

Homeopathy is quackery that dilutes organic or anorganic materials (that randomly got associated with symptoms, e.g. Berlin Wall against binding problems) to infinity to treat an existing condition.
Every high-quality scientific study leads to the realisation that Homeopathy doesn’t act beyond placebo effects.
