Penanganan Rantai Dingin dalam Pembuatan Vaksin: Mengapa Ini Penting?
Maintaining vaccines at the correct temperature is crucial to protect their potency and ensure patient safety. Cold chain handling in vaccine manufacturing involves every step—from temperaturecontrolled production and packaging to transport and storage at the point of care. Menurut Organisasi Kesehatan Dunia (SIAPA), most vaccines must be kept between 2 °C dan 8°C, while oral polio vaccine requires –25 °C to –15 °C penyimpanan. AS. Pusat Pengendalian dan Pencegahan Penyakit (CDC) stresses that exposure to temperatures outside these ranges reduces potency and may necessitate revaccination. With the global vaccine storage and packaging market projected to grow from KITA $4.78 miliar masuk 2024 ke $8.11 miliar oleh 2030, understanding cold chain handling is vital for manufacturers, healthcare providers and logistics partners.

What Is the Cold Chain and Why Does Vaccine Manufacturing Depend on It?
Defining the Vaccine Cold Chain
Itu Rantai dingin vaksin adalah a rantai pasokan yang dikontrol suhu that includes all equipment and procedures related to vaccines. It starts with cold storage at the manufacturing plant, continues through transport and storage at healthcare facilities, and ends when the vaccine is administered. Produsen, distributor, public health staff and providers share responsibility to maintain this chain. Breaking the chain can destroy potency: exposure to freezing temperatures (0 °C or colder) can permanently destroy vaccines containing aluminum adjuvants.
Komponen Kunci Rantai Dingin
An effective cold chain has tiga elemen utama:
Staf yang terlatih – personnel must understand storage, packaging and emergency procedures.
Reliable equipment – dedicated pharmaceutical refrigerators, freezer (including ultracold units) and digital temperature monitoring devices are essential.
Manajemen inventaris yang akurat – stock rotation, date labels and recordkeeping help prevent wastage.
A stylized diagram visualizes the vaccine cold chain from manufacturing to clinic. Arrows show the journey from the manufacturing plant through refrigerated trucks and data loggers to the final storage unit, highlighting the importance of continuous temperature control.
Konsekuensi Kegagalan Rantai Dingin
Ketika rantai dingin gagal, patients may require revaccination, and providers incur significant costs. The CDC notes that potency is lost each time a vaccine is exposed to an improper condition. Inactivated vaccines may not appear compromised even if exposed to freezing temperatures, making visual inspection unreliable. A comprehensive compliance guide from Lascar Electronics adds that even brief excursions outside the +2 ° C ke +8 °C window can invalidate an entire batch and lead to regulatory penalties and public health risks.
How Do Manufacturing Facilities Ensure Cold Chain Compliance?
Specialized Storage at the Plant
Manufacturing and initial storage lay the foundation for cold chain integrity. As soon as vaccines are produced, they are transferred into dedicated lowtemperature storage facilities equipped with specialized cooling systems. These facilities often include lemari es kelas farmasi, freezer dan freezer ultra rendah capable of maintaining consistent temperatures. Misalnya:
Lemari es: menjaga 2 °C – 8 ° C., suitable for most live and inactivated vaccines.
freezer: menjaga –50 °C – –15 °C, used for certain vaccines and diluents.
Freezer yang sangat dingin: menjaga –90 °C – –60 °C, required for some mRNA vaccines and cell therapies.
These units should be purposebuilt or pharmaceuticalgrade, not household refrigerators, because domestic units have temperature fluctuations and cold spots.
Perangkat pemantauan suhu
Every storage unit must have a alat pemantau suhu (TMD). CDC merekomendasikan pencatat data digital (DDL) because they record temperatures at preset intervals and provide details about excursions. Fitur utama termasuk:
Probe yang disangga using glycol or glass beads to reflect vaccine temperatures.
Alarm dan indikator baterai lemah.
Accuracy of ±0.5 °C dan interval logging setidaknya 30 menit.
Valid calibration certificates, with calibration performed every 2–3 years.
Mempertahankan backup TMDs ensures continuous monitoring if the primary device fails.
Prosedur Operasi Standar (Sops) and Staff Training
Facilities need detailed storage and handling SOPs covering routine procedures (pemesanan, menerima, penyimpanan dan pemantauan vaksin) and emergency protocols (power outages or equipment failures). Staff should be trained during orientation and annually thereafter. Yang ditunjuk koordinator vaksin oversees ordering, manajemen inventaris, temperature monitoring and emergency responses.
Which Packaging and Transport Strategies Maintain Temperature Integrity?
Packaging Components for Safe Transport
Pharmaceutical cold chain packaging must be more than simple insulation—it is an engineered system that combines insulation, pendingin dan perangkat pemantauan. According to Tempk’s cold chain packaging guide, packaging systems typically include:
| Komponen | Fungsi | Manfaat praktis |
| Wadah terisolasi | Outer shell made of EPS, polyurethane or vacuum insulated panels. | Minimizes heat transfer to maintain stable internal temperatures. |
| Pendingin | Paket gel, dry ice or phasechange materials absorb/release heat. | Maintains desired temperature range during transit. |
| Pemantauan suhu | Data loggers or realtime IoT sensors track conditions. | Provides proof of compliance and alerts for excursions. |
| Protective packaging | Bungkus gelembung, foam and outer cartons. | Absorbs shocks and communicates handling instructions. |
Tips Praktis: match packaging to your product’s temperature class (standard vaccines at 2–8 °C, biologics at –20 °C or –80 °C), validate performance through modeling or testing, train staff on packing SOPs, and build redundancy with backup refrigerants.
Controlled Temperature Chain and Passive Cooling
The WHO notes that live vaccines are generally stored between +2 °C dan +8 ° C., while oral polio vaccine (OPV) is stored at –25 °C to –15 °C. Freezedried vaccines bundled with their diluent should never be frozen; they should be stored at +2 ° C ke +8 ° C.. In areas lacking continuous power, rantai suhu terkendali (CTC) approaches allow some heatstable vaccines to be stored at temperatures up to 40 °C for a limited time. Passive cooling devices such as vaccine carriers with phasechange materials Dan paket pendingin maintain temperature during outreach operations and are crucial in lowresource settings.
Transport Logistics and RealTime Monitoring
Selama transportasi, vaccines must stay within the prescribed temperature range. Truk berpendingin, temperaturecontrolled containers and cold boxes are standard. Data loggers and Sensor IoT enable realtime tracking of temperature and location. Jika terjadi tamasya, the system triggers alerts for immediate corrective actions. IoT devices with GPS also support optimalisasi rute by integrating traffic and weather data.
To minimise delays and temperature fluctuations, plan shipping routes to avoid long dwell times or customs holds. Gunakan wadah yang tervalidasi and limit door openings during loading and unloading. Untuk pengiriman internasional, consult Good Distribution Practices and countryspecific regulations to ensure compliance.
How to Monitor and Respond to Temperature Excursions
Pemantauan Berkelanjutan dan Pencatatan Data
Maintaining compliance requires 24/7 pemantauan. Lascar Electronics’ guide recommends automated data loggers that track temperatures continuously during storage and transport. Realtime monitoring platforms (MISALNYA., cloudbased systems) menawarkan:
Secure digital records with audit trails and electronic signatures.
Email/SMS alerts when temperatures approach limits.
Calibration and probe options for accurate readings that simulate product temperature.
Risk Management and Response
A comprehensive cold chain compliance program includes manajemen risiko proaktif. Identify potential vulnerabilities such as power outages, equipment failures or long unloading times and implement contingency plans. Standard responses to excursions include:
Assess the temperature excursion – determine duration and temperature range; consult vaccine manufacturers for stability data.
Segregate and quarantine affected vaccines sampai kelangsungan hidup dikonfirmasi.
Contact health authorities for guidance on whether to use or discard the affected doses.
Dokumentasikan kejadian tersebut in temperature logs and report to regulatory agencies if required.
Training staff to recognise and respond to excursions is critical. Unplanned exposures may necessitate revaccination and can erode public trust.
What Are the Regulatory Requirements for Vaccine Cold Chain Compliance?
Praktek Manufaktur yang Baik (GMP) dan Praktik Distribusi yang Baik (PDB)
AS. Administrasi Makanan dan Obat -obatan (FDA) requires manufacturers to follow Praktik Manufaktur yang Baik Saat Ini (CGMP) peraturan. These regulations set minimum requirements for manufacturing, processing and packaging and ensure that products are safe, contain the claimed ingredients and meet quality standards. Compliance is assessed during new drug application reviews and routine inspections.
Praktik Distribusi yang Baik (PDB) govern distribution and emphasise validated systems, kontrol suhu, ketertelusuran dan personel yang terlatih. Compliance requires calibration to standards like NIST atau UKAS to ensure measurement accuracy and adherence to data integrity guidelines such as Lampiran GMP UE 11.
WHO and CDC Recommendations
The WHO’s Vaccine Management Handbook advises storing most vaccines at +2 ° C ke +8 ° C. and freezedried vaccines packed separately at –25 °C to –15 °C. Diluents bundled with vaccines should never be frozen and should be stored at +2 ° C ke +8 ° C.. The CDC’s Storage and Handling Toolkit echoes these recommendations and provides detailed guidance on storage units, pemantauan suhu, SOPs and emergency plans.
Calibration and Documentation
Regulations require that temperature monitoring devices be calibrated regularly and have traceable certificates. Facilities must keep temperature data for at least 3 bertahun-tahun (longer if required by local law). Detailed documentation is necessary for audits, including calibration records, log pelatihan, and incident reports.
