C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Live, attenuated vaccine; following immunization, immunogenicity occurs by antibody response; seroconversion is defined as antirotavirus IgA antibodies >20 U/mL post-vaccination; conveys active immunity via stimulation of production of endogenously produced antibodies
Replicates in small intestine and incudes immunity
Rotarix is indicated for prevention of rotavirus gastroenteritis caused by serotypes G1, G3, G4, and G9; RotaTeq is indicated for gastroenteritis caused by serotypes G1, G2, G3, and G4; both vaccines may provide immunity to other serotypes
Pharmacokinetics
Onset: Antirotavirus IgA antibodies noted 1-2 months in 77-87% of infants after 2 doses administered for Rotarix; antirotavirus antibodies noted after 3 doses in 93-100% of infants for RotaTeq
Duration: Efficacy was at 70-79% against any grade of rotavirus through two seasons
