PMID 35579368WHAT IT FOUND
A drive-through vaccination unit in São Paulo gave 9,698 doses over 25 days.
Missed doses were 1.8%, and staff used safety huddles, dose checks and cold-chain controls. It describes operations, not proof the model works.
Key findings
01During 25 days of operation, the unit administered 9,698 doses of immunizing agents.
02The percentage of missed doses was 1.8%, and no losses of doses due to any other condition were reported during the activities.
03The safety huddle was led by a nurse, and applicators were oriented to standardized transparent vaccine administration steps.

What it does not show
This is an experience report, not a trial, so it cannot show that the drive-through model works better than other vaccination settings. The researchers worked in the unit's planning and leadership team, which may affect the description. The report gives operational counts and missed-dose information, but not patient outcomes, adverse events or comparison data. Staffing was based on a proportion of installed capacity, not on evidence for optimal team size. The team was itinerant and required repeated training, so the experience may not transfer to a fixed team.
Declared interests
No funding or conflict-of-interest declaration is stated in the article. The researchers worked at Hospital Albert Einstein, which had a 20-year agreement with the Municipal Health Department.
The easy way to misread this
Do not read the 9,698 doses and 1.8% missed doses as proof the drive-through model is safer or more efficient than other vaccination settings. This report has no comparison group and no patient outcomes, so it describes this unit's operation only.
