Background:

Development of novel vaccines and adjuvants is critical for global health challenges like HIV, hepatitis C, tuberculosis, and malaria.
Identifying effective adjuvants is ongoing, but a major obstacle to clinical use is reactogenicity (undesirable side effects).
Current methods for screening vaccine reactogenicity in small animal models lack sensitivity and high-throughput capacity.

Purpose of the Study:

To establish a sensitive, high-throughput screening method for assessing vaccine reactogenicity.
To evaluate the utility of multiparameter telemetry in laboratory mice for detecting subtle systemic side-effects of vaccination.

Main Methods:

Continuous telemetric monitoring of physiological parameters in laboratory mice, including heart rate, heart rate variability, body core temperature, and locomotor activity.
Comparison of telemetry data with conventional observational assessment and clinical scoring to identify vaccine-induced changes.
Assessment of the scalability and automation potential of telemetry for industrial applications.

Main Results:

Multiparameter telemetry successfully detected systemic vaccine side-effects that were missed by conventional methods.
Subtle homeostatic disturbances, including sympathetic activation, pyrogenic effects, and reduced activity, were readily identified in real-time.
Telemetry demonstrated sensitivity to minor physiological aberrations, providing a more comprehensive assessment of reactogenicity.

Conclusions:

Continuous multiparameter telemetry in mice offers a sensitive and scalable platform for first-line screening of vaccine reactogenicity.
This approach can accelerate vaccine discovery and development by providing early detection of potential safety concerns.
Improved assessment of reactogenicity may enhance the success of vaccines against infectious diseases and cancer.
