Abstract

MAI, Scheila et al. Vaccine dose usage and wastage in the Metropolitan Region of Porto Alegre, Rio Grande do Sul, Brazil: a descriptive study, 2015-2017. Epidemiol. Serv. Saúde [online]. 2019, vol.28, n.3, e2018389.  Epub Feb 03, 2020. ISSN 2237-9622.  https://doi.org/10.5123/s1679-49742019000300016.

Objective:

to estimate usage and wastage of multi-dose and single-dose vaccine vials in the Metropolitan Region of Porto Alegre, Rio Grande do Sul, Brazil, from 2015 to 2017.

Methods:

a descriptive study was carried out based on secondary data from the National Immunization Program Information System (SIPNI) and the Strategic Health Supplies Information System (SIES).

Results:

a total of 12,342 records were examined; mean wastage rate was 45.8% (95%CI 39.5;51.7), while usage rate was 54.2% (95%CI 48.3;60.5); vaccines with the highest mean annual wastage rate were MMR (68.8% - 95%CI 66.5;71.1), BCG (68.1% - 95%CI 65.4;70.7), Hepatitis B (56.4% - 95%CI 53.0-59.7) and Yellow Fever (55.9% - 95%CI 51.4;60.4).

Conclusion:

the highest rates of vaccine wastage were for multi-dose vials; although single-dose vaccines also exceeded the acceptable limit defined by the World Health Organization.
