Effective vaccines against toxoplasmosis do not exist due to complex parasite biology
the verdict
SUPPORTED
the evidence backs this
confidence 78/100
Effective human vaccines against toxoplasmosis currently do not exist, hampered by the parasite's complex intracellular biology, immune evasion mechanisms, and strain diversity.
