Mechanism of action

The vaccine contains weakened (attenuated) rotavirus strains that can replicate in the intestinal epithelium but have reduced virulence. This replication triggers both mucosal and systemic immune responses, including the production of neutralizing antibodies and cellular immunity against rotavirus antigens. The attenuated virus provides protection against wild-type rotavirus infection while minimizing the risk of vaccine-strain disease.
