A vaccine is a preventive drug that protects the recipient against various diseases. Vaccines will contain the same germs that cause the disease, but in a killed or weakened state, ensuring that whoever takes the vaccine won’t get sick. The body’s immune system will produce antibodies and will develop an immunity to that disease without having ever had the disease.
There are various types of vaccines:
Immunization is the process by which a person or animal becomes protected against a disease.
When transporting vaccines at low temperatures, dry ice can be used. Dry ice is CO2 in its solid phase, carbon dioxide turn into dry ice at –78.5°C (at 1 atm). Dry ice is often used as a coolant due to the fact that it is colder than water ice and that CO2 has no liquid phase in standard atmospheric conditions meaning that when dry ice melts, there is only an increase of CO2 levels but no other residues. As CO2 is an odourless and colourless gas, it is very important for life safety to always monitor the CO2 level when using dry ice. CO2 is capable of causing asphyxiation at high concentrations!
To ensure the product quality, vaccines are manufactured in sterile environments and temperature-controlled environments. Vaccines are fragile and must be maintained at recommended temperatures, from manufacturing to administration, to ensure that they don’t deteriorate. The temperature range will depend on the vaccines. For example, the Pfizer/BioNTech COVID-19 vaccine must be stored at -70°C, whereas the majority of vaccines can be stored in a fridge between 2…8°C.
Various regulations exist to ensure the product quality during the distribution of vaccines:
It is important for a facility to have proper storage and monitoring equipment and based upon the GDP regulations, the equipment must be set up correctly, maintained appropriately including a frequent calibration and repaired as needed. This will ensure that the vaccines cold chain is not broken, and the vaccines integrity is not compromised meaning that patients are not receiving compromised vaccines or being vaccine twice and potentially expensive vaccines don’t have to be disposed of.
The Rotronic continuous and configurable environmental monitoring system can monitor all stages of the lifetime of a vaccine: from the initial pharmaceutical quality, via the non-clinical trials, the clinical trials and the scientific evaluation and authorisation, then onto the large-scale production, distribution and storage of vaccines.
The Rotronic Monitoring System (RMS) is a GAMP©5 category 4 software combined with category 1 hardware, helping users monitor their GxP compliant applications, looking into the critical quality attributes and monitoring critical process parameters, helping focus on patient safety, product quality and data integrity and compliant to EudraLex Annex 11 and FDA 21 CFR Part 11.
RMS helps reduce human interaction and reduces risk (every day taking temperature values on paper).

ROTRONIC SERVICES
Rotronic can offer calibration and qualification of temperature controlled areas and product training.
The Gateway is the interface between the wireless data logger and the server software.
Data logger with two integrated analog-to-digital converters, to which two PT100 sensors can be connected for high-precision temperature measurement.
Autonomous operation on failure.
The sensor holder is traceable end-to-end and meets all FDA and GxP environments.
The RMS-TCD-S-001 is a completely digital designed probe for the Rotronic Monitoring System RMS. It measures temperature.
The RMS-LOG-T30 is a data logger with two integrated analog-to-digital converters, to which two PT100 sensors can be connected for high-precision temperature measurement.
The T10 temperature sensors are NTC (Negative Temperature Coefficient) thermistors, meaning that the resistance of the NTC decreases with increasing temperature. The T10 temperature sensors are compatible with the RMS-MLOG-T10-868/915 data loggers.
