which was the health company that analysed the vax for its own employees and found a dose dependent response to the vax
The short version: the study you're thinking of is a Japanese corporate-employee genome study, not a health company's own internal analysis, and it did not report a dose-dependent harm signal.
The closest match in this retrieval is a genome-wide association study of 2,554 Japanese corporate employees that looked at side effects after COVID-19 booster shots and found six genetic loci tied to symptom severity, including lymph-node swelling and injection-site induration [1]. That is a genetic-susceptibility study, not a dose-response finding, and the company is not named in the record.
A separate Finnish survey of people reporting post-injection harms describes a suggested dose-response pattern, with 40 of 48 worsening after the next dose and 37 of 48 adding new symptoms [3]. That is a self-selected online survey of 63 completers, not a company analyzing its own workforce.
| Study | Population | What it found |
|---|---|---|
| Japanese GWAS [1] | 2,554 corporate employees | Six gene loci tied to side-effect severity |
| Finnish survey [3] | 63 self-selected respondents | 83% worsened after next dose |
| MOSAICO [2] | Healthcare workers | Prior side effects predicted repeat side effects |
The specific "health company analyzed its own employees' vax and found dose-dependent response" study is not in this retrieval. I cannot confirm which company it was or what it found. If you can name the company or the year, I can tell you whether the design would support a dose-response claim.
My call: the study you are describing is not identifiable from what I have, and the nearest matches are a genetic study and a voluntary survey, neither of which is a company's internal dose-response analysis. Confidence: low.

Genome-wide association study of common side effects following COVID-19 booster vaccination in a cohort of corporate employees in Japan
This study conducted a genome-wide association study (GWAS) on 2,554 Japanese corporate employees to identify genetic factors associated with the severity of common side effects following COVID-19 booster vaccinations, revealing six significant loci linked to adverse symptoms.

Risk of Repeated Adverse Effects following Booster Dose of mRNA COVID-19 Vaccine: Results from the MOSAICO Study
This study investigates the risk of repeated adverse effects following a booster dose of mRNA COVID-19 vaccines among healthcare workers, revealing that prior experiences of adverse effects significantly predict the likelihood of similar reactions after subsequent doses.
