Covid-19 Vaccinated Serum
Powered by BiozAbout:Covid-19 Vaccinated Serum - human serum from donors with confirmed COVID-19 vaccination history, processed within 24 hours. Ideal for neutralizing antibody titers, vaccine platform comparison, hybrid immunity research, and variant cross-reactivity studies. Stratification by vaccine platform, dose count, booster history, and prior infection status.
About Covid-19 Vaccinated Serum
Covid-19 Vaccinated Serum for Vaccine Immunogenicity Research
Our Covid-19 Vaccinated Serum is sourced from IRB-consented donors with a confirmed COVID-19 vaccination history. Each sample is processed and frozen within 24 hours of collection to preserve circulating antibodies and cytokines for downstream vaccine immunogenicity and immune response research.
Covid-19 Vaccination Biology and Why Serum
- SARS-CoV-2 vaccines, including mRNA (BNT162b2, mRNA-1273), viral vector, and protein subunit platforms, elicit spike-protein-specific antibody and T-cell responses that vary in magnitude and durability by platform, dose number, and time since vaccination.
- Neutralizing antibody titers, spike-specific IgG, and IgA responses are central readouts for vaccine immunogenicity studies and for assessing protection against emerging variants; serum is the standard matrix for most validated commercial and reference serology assays.
- Hybrid immunity – the combination of vaccination and prior infection – produces distinct antibody breadth and durability profiles compared to vaccination alone, making vaccination and infection history jointly important donor variables.
- Waning antibody titers over time and the emergence of immune-evasive variants have driven ongoing demand for updated bivalent and variant-specific booster response data.
- Serum is widely used for cytokine and inflammatory marker panels alongside antibody titers in vaccine reactogenicity and immunogenicity studies.

Where can I find your complete catalog?
You can find our full product catalog here.
How long can samples be stored?
Storage depends on sample type but often cryopreserved samples stored in liquid nitrogen can be stored for years.
What customization options are available?
Extensive customization is available. To discuss your project request a quote or email us at learnmore@sanguinebio.com.
Do you offer prospective collections?
Sanguine offers flexible prospective collection services tailored to fit your research. For more information and to request a quote, please see: our prospective biospecimen collection services page.
What is the turnaround time for custom collections?
Timelines depend on condition, sample type, and I/E criteria but we often start collection within 2 weeks of signed agreement.
Do you have samples in stock?
YES - we have in-stock inventory. You can also email us at learnmore@sanguinebio.com as we continually get new samples in our inventory.
What does unique donor mean?
Each sample from a different individual - Unique donor means each sample comes from a different person, ensuring biological diversity in your study.
Are samples collected under IRB-approved protocols?
YES - "IRB-approved collection protocols" and IRB approval documentation available upon request. Sanguine utilizes two internationally-recognized IRBs (Advarra and WCG IRB) for review and approval.
