Which human health risk is associated with certain neurotropic AHS vaccine strains?

Neurotropic vaccine strains have a propensity to invade neural tissues, so when humans are exposed to certain AHS vaccine strains with this characteristic, the most notable health risk is inflammation of the brain and the retina. Encephalitis reflects brain involvement, while retinitis reflects eye involvement, together representing the classic CNS and ocular adverse effects seen with these strains. This pattern is more specific to these neurotropic strains than to respiratory or purely meningitic presentations, which is why encephalitis and retinitis is the best-fit risk. Other options like pneumonia are not typical manifestations of this neurotropic profile, and while meningitis can occur in CNS infections, the characteristic combination here is encephalitis with retinitis.
