Because it is weakened, the pathogen will not spread and cause sickness, but the immune system will still learn to recognize its antigens and know to fight in the future.

Why is it easier to attenuate viruses than bacteria?

Answer. It may be because most viruses are genetically less complex than bacteria and contain only a small number of genes, so a few mutations can result in attenuation of pathogenicity. Also most viruses mutate more quickly, so a variant with useful properties in a vaccine is likely to arise more frequently.
