#### Specify age groups (in weeks)

### Weekly number of doses

#### C1. Dose 1: number of doses

Number of doses (dose 1) extrapolated to the whole UK population by age groups (as specified above), by calendar time (in weeks).

#### C2. Dose 2: number of doses

Number of doses (dose 2) extrapolated to the whole UK population by age groups (as specified above), by calendar time (in weeks).

### Figure: Incidence rate (/10.000 person years) of intussusception

#### R1. Dose 1 - Risk Window 1 (1-7 days)

Incidence rate per 10.000 person years [95% CI] of intussusception estimated cumulatively over time, baseline incidence prior to vaccination introduction (age 8 to 10 weeks) and incidence 1-7 days after dose 1.

#### R2. Dose 1 - Risk Window 2 (8-21 days)

Incidence rate per 10.000 person years [95% CI] of intussusception estimated cumulatively over time, baseline incidence prior to vaccination introduction (age 9 to 12 weeks) and incidence 8-21 days after dose 1.

#### R3. Dose 2 - Risk Window 1 (1-7 days)

Incidence rate per 10.000 person years [95% CI] of intussusception estimated cumulatively over time, baseline incidence prior to vaccination introduction (age 12 to 14 weeks) and incidence 1-7 days after dose 1.

#### R4. Dose 2 - Risk Window 2 (8-21 days)

Incidence rate per 10.000 person years [95% CI] of intussusception estimated cumulatively over time, baseline incidence prior to vaccination introduction (age 13 to 16 weeks) and incidence 8-21 days after dose 1.

### Figure: Running incidence rate (/ 10.000 person years) of acute gastroenteritis (AGE), total population

#### B1. GP Visits

Incidence rate per 10.000 person years [95% CI] of AGE GP visits in total population with a lookback period specified above.

#### B2. Hospital Admissions

Incidence rate per 10.000 person years [95% CI] of AGE hospital admissions in total population with a lookback period specified above.

### Figure: Benefit-Risk of rota-virus vaccination, total population (observed benefits)

#### BRT1. Benefit - Risk Difference

Benefit-risk difference [95% CI] in a partially vaccinated population of 10.000 children followed from birth till 1 year of age. The benefit-risk difference is calculated as a weighted sum of the population-level observed vaccine prevented disease burden (baseline incidence minus incidence post-vaccination) and the weighted population-level vaccine induced disease burden (excess incidence). The coverage of the population is as observed. The length of the lookback period for the benefits and the weights and baseline values for the benefit-risk measures are specified above.

#### BRT2. Benefit - Risk Ratio

Average benefit-risk ratio [95% CI] for children followed from birth till 1 year of age from a partially vaccinated population. The benefit-risk ratio is calculated as the weighted vaccine prevented disease burden (baseline incidence minus incidence post-vaccination) to the weighted vaccine induced disease burden (excess incidence). The coverage of the population is as observed. The length of the lookback period for the benefits and the weights and baseline values for the benefit-risk measures are specified above.

### Figure: Benefit-Risk of rota-virus vaccination, vaccinated population (expected benefits)

#### BRT3. Benefit - Risk Difference

Benefit-risk difference [95% CI] per 10.000 vaccinated children followed from birth till 1 year of age. The benefit-risk difference is calculated as a weighted sum of the theoretical vaccine prevented disease burden (baseline incidence minus incidence in vaccinated subjects given the expected vaccine effectiveness as specified above) and the weighted vaccine induced disease burden (excess incidence). The weights and baseline values are specified above.

#### BRT4. Benefit - Risk Ratio

Benefit-risk ratio [95% CI] for vaccinated children followed from birth till 1 year of age. The benefit-risk ratio is calculated as the weighted theoretical vaccine prevented disease burden (baseline incidence minus incidence in vaccinated subjects given the expected vaccine effectiveness as specified above) to the weighted vaccine induced disease burden (excess incidence). The weights and baseline values are specified above.
