Outcome measures

A. Health-related benefits to vaccinated individuals

  A1. Health gains

Reduction in morbidity and mortality

Cases averted

Deaths averted

QALYs/DALYs saved

  A2. Health care cost savings

Reduction in direct cost of health care borne by the public sector or private individuals

Costs saved by health care provider

Health care costs saved by individuals

B. Productivity-related benefits

  B1. Productivity gains related to care

Reduction in lost days of work due to caring for a sick patient

Value of productivity

  B2. Productivity gains related to health effects

Reduction in lost days of work due to sickness or death of a sick patient

Friction costs

Potential lifetime earnings

  B3. Productivity gains related to non-utility capabilitiesa

Increased lifetime productivity because of enhanced capabilities (such as improved cognition and educational attainment) not easily measured using utility-based preference measures

Educational outcomes

Cognitive outcomes

Potential lifetime earnings

C. Community or health systems externalities

  C1. Ecological effects

Health improvements in unvaccinated community members as a result of ecological effects such as herd immunity, eradication, and reduced antibiotic usage

Indirect vaccine protection

Prevalence of antibiotic resistance

Future cost of disease control averted

  C2. Equity

More equal distribution of health outcomes

Distribution of health outcomes

  C3. Financial and programmatic synergies and sustainability

Improved financial sustainability as a result of effects such as synergies with other health care programmes (e.g. delivery platforms), stimulation of private demand, and mechanisms to enhance group purchasing power (e.g. PAHO revolving fund)

Financial benefits

Private demand estimates

  C4. Household security

Improved financial security of households as a result of reduced risk of catastrophic expenditure

Actuarial value of security

D. Broader economic indicators

  D1. Changes to household behaviour

Economic improvements due to changes in household choices such as fertility and consumption/saving as a result of improved child health and survival

Productivity

Female labour participation

Household investment

Child dependency ratio

  D2. Public sector budget impact

Change to an individual’s net transfers to the national budget over his/her lifetime

Return on investment

Net present value of investment

  D3. Short-term macroeconomic impact

Changes to national income or production as a result of short-term exogeneous shocks to the economy

Change in GDP (per capita)

Change in sectoral output

  D4. Long-term macroeconomic impact

Changes to national income or production as a result of long-term changes to drivers such as labour supply and foreign direct investment

Change in GDP (per capita)

  1. aMost cost-effectiveness evaluations focus on maximising individual preference-based measures of health. Capabilities refer to the ability of individuals to function in particular ways, and offer an alternative way to assess the value of health-altering interventions [46]
