Table includes all vaccinated participants. Pre-defined risk factors include chronic liver, lung, and heart disease, diabetes mellitus, tobacco use, and alcohol consumption.
AUDIT-C: Alcohol Use Disorders Identification Test – Consumption; PCV13: 13-valent pneumococcal conjugate vaccine; V114: 15-valent pneumococcal conjugate vaccine.
†Participant is counted for each applicable row and column.
‡Actual strata assignments were used in the summaries of risk factors.
§The risk factor of alcohol consumption is defined as an AUDIT-C score ≥5.
