UNIVAC version 2.1 released on 10th October 2025 included the following updates:

1. Updated default input assumptions for cervical cancer lesion costs.

2. Added reminder for user to 'reselect' the country after changing the custom setup assumptions (this ensures correct transfer of default inputs).

UNIVAC version 2.0 released on 1st October 2025 included the following updates:

1. Demographic projections updated to UNWPP 2024 revision estimates. 

2. Stillbirth rates and projections updated to UNICEF Jan 2023 estimates.

3. BCG, DTP1-3 and MCV1 vaccine coverage assumptions (proxy values for new vaccines) updated to WUENIC Sept 2024 estimates.

4. Various updates to RSV burden and intervention efficacy input parameters.

5. Minor updates to language (Spanish translations, and help button pop-ups).

UNIVAC version 1.9 released on 19th August 2024 included the following updates:

1. Bug fixed in formulae for the YLD component of DALY calculation for HPV vaccine evaluations.

UNIVAC version 1.8 released on 9th May 2024 included the following updates:

1. A 'perspectives helper sheet' has been added to help national teams better define the perspective/s of the analysis.

2. New default data for rotavirus disease treatment costs (now updated to reflect the year 2022).

3. New default data for the effectiveness of 1 dose of rotavirus vaccination compared to 2/3 doses based on a new meta-analysis of case control studies (see appendix to Clark et al, IJID 2023)

UNIVAC version 1.7 released on 31st January 2023 included the following updates:

1. Disease mortality trend inputs were expanded to the year 2100 using the latest trends in under-five mortality published by the United Nations World Population Prospects (UNWPP 2022 revision) estimates. These trends are relevant if the user chooses to apply a counterfactual disease mortality trend (in the absence of vaccination) and can be overridden by the national team if required.

UNIVAC version 1.6 released on 21st December 2022 included the following updates:

1. Demography updated to the latest United Nations World Population Prospects (UNWPP 2022 revision) estimates;

3. New option to evaluate the impact and cost-effectiveness of maternal RSV vaccination to protect newborns;

4. New option to evaluate the impact and cost-effectiveness of a long-lasting monoclonal RSV antibody given shortly after birth;

5. Added option to use 'live births' when calculating programme costs for birth interventions;

6. Updated rotavirus mortality estimates to reflect new GBD2019 data and updated MCEE 2006-2019 estimates of all-cause diarrhoea mortality;

7. Updated vaccine coverage estimates to reflect most recent WHO/UNICEF joint estimates (updated 15th July 2022); and,

8. Updated country income status to reflect World Bank 2022-23 estimates (as of 1st July 2022).
