Category Metricsa
COVID-19 vaccine administration
  • -

    Number of total doses administered

    Number of total doses administered per 100,000 persons

    Number of persons who received at least one dose

    Number of persons fully vaccinated

    Change in number doses administered since last week (total doses, total doses per 100,000 persons, persons who received at least one dose, persons fully vaccinated)

    Number of persons who received at least one dose and number persons fully vaccinated over time, by week

    Number of doses administered by vaccine manufacturer and dose number, where applicable

    Number of persons who received at least one dose and number persons fully vaccinated by demographics (i.e., sex, age group, race/ethnicity, VSD site, high-risk for COVID-19 disease status, and COVID-19 disease history status) and by week


COVID-19 vaccine coverage
  • -

    Number and proportion of VSD population who received at least one dose

    Number and proportion of VSD population fully vaccinated

    Number and proportion of VSD population who received vaccine, by vaccine manufacturer and dose number

    Number and proportion of VSD population who received dose 1 and number and proportion of VSD population who received dose 2, by vaccine manufacturer and demographics

    Number and proportion of VSD population who received at least one dose and number and proportion of VSD population fully vaccinated by demographics and by week


Descriptive summaries of outcomes following COVID-19 vaccination
  • -

    Number of pre-specified outcomes that occurred by outcome type, vaccine manufacturer and dose number

    Number of pre-specified outcomes that occurred by outcome type, vaccine manufacturer and dose number, average days to onset/diagnosis, sex, pregnancy status, and history of COVID-19 disease status

    Outcome-specific visualizations that show number of outcomes by vaccine manufacturer and dose number, demographics, pregnancy status, and days to outcome diagnosis

    Number of pre-specified outcomes by days since onset and rate per one million person-days, by pre-specified outcome


Statistical analyses of COVID-19 vaccine outcomes
  • -

    Cumulative incidence of pre-specified outcomes during pre-specified post-vaccination risk intervals

    Rate ratios to estimate the ratio of outcome incidence in the risk interval to the outcome incidence in the comparison interval with 95% confidence intervals

    Sequential analyses results of the one-sided null hypothesis that the vaccine does not increase risk of outcome during the risk interval


COVID-19 disease hospitalization counts
  • -

    Number of total COVID-19 hospitalizations among VSD population over time, by month

    Number of total COVID-19 hospitalizations among VSD population over time (by month), compared to total number of dose 1 and dose 2 COVID-19 vaccine doses administered over time (by month)

    Number of total COVID-19 hospitalizations among VSD population over time (by month), by demographics

    Number of total lab-positive COVID-19 hospitalizations among VSD population over time (by month), by demographics

    Number and proportion of deceased lab-positive COVID-19 hospitalized persons by sex and age group (denominator = all lab-positive COVID-19 hospitalized persons)


Descriptive summaries of simultaneous vaccine administration with COVID-19 vaccine (i.e., administration of a non-COVID-19 vaccine on same day as a COVID-19 vaccine)
  • -

    Number of persons who received simultaneous vaccines with any dose of COVID-19 vaccine compared to number persons who initiated COVID-19 vaccine

    Number of persons who received simultaneous vaccinations with COVID-19 vaccine, by COVID-19 vaccine manufacturer, dose number, and demographics

Number and proportion of pregnant persons hospitalized (denominator = total number women hospitalized of childbearing age)
Number of pregnant persons hospitalized by race/ethnicity and VSD site
Minimum, median, and maximum: 1) woman’s age at COVID-19 diagnosis in years; 2) number hospitalizations during pregnancy; 3) duration of hospital stay in days; 4) time from COVID-19 diagnosis to delivery; 5) gestational age at time of delivery in weeks
Number and proportion of pregnancy outcomes among women with an outcome (i.e., live born delivery; spontaneous abortion; live born or stillborn delivery; stillborn; therapeutic abortion; ectopic pregnancy)
Number babies born preterm
