INTRODUCTION
By July 2023, Brazil had administered approximately 540 million COVID-19 vaccine doses. This study aimed to quantify wasted doses resulting from dead space in vaccine supplies.
METHODS
The vaccine supply was initially weighed, filled with distilled water, and expelled to simulate administration. Weighing it again after the application determined the dead space volume. Descriptive analyses calculated the waste rate/wasted dose count.
RESULTS
The estimated total number of wasted vaccine doses using supplies with the lowest dead space was 62,097,338.
CONCLUSIONS
Syringe dead space is a crucial factor in dose wastage, directly influencing the number of wasted doses.
简介
截至 2023 年 7 月，巴西已接种约 5.4 亿剂 COVID-19 疫苗。本研究旨在量化疫苗供应中因死腔而造成的浪费剂量。
方法
疫苗供应最初称重，注入蒸馏水并挤出以模拟接种。接种后再次称重以确定死腔体积。描述性分析计算了浪费率/浪费剂量数。
结果
使用死腔最小的供应品，估计浪费的疫苗剂量总数为 62097338 剂。
结论
注射器死腔是剂量浪费的一个关键因素，直接影响浪费剂量的数量。
