|Age Years||No. vaccine doses||No. of OAE*a||OAE* reported/ 100,000 doses||RRR (95% CI)||#SyAE*b||SyAE* reported/ 100,000 doses||RRR (95% CI)|
|15-24||189,991||12||6.32||1.8 (0.9-3.5)||2||1.05||3.7 (0.5-26)|
|45-64||442,605||15||3.39||1.0 (0.5-1.8)||5||1.13||4.0 (0.8-20)|

aOAE*= other adverse events (i.e., uncomplicated neurologic or systemic event; hypersensitivity; local reaction) OR systemic adverse events not requiring hospitalization or resulting in death.
bSyAE* = serious systemic adverse events, including only neurologic or multisystemic adverse events requiring hospitalization or resulting in death; this is distinguished from the term SyAE, which indicates all systemic adverse events (See Table 2).
CI = confidence intervals.
