How Cold Chain Monitoring System to Ensure the Covid-19 Vaccine Safety ?  

China announced the approval of inactivated COVID-19 vaccines for emergency use in children age between 3-17.The announcement was made by the country’s National Health Commission, Chinese public broadcaster CGTN reported. Until now, China has approved three vaccines including Sinovac and Sinopharm which have also been approved by the World Health Organization.

Sinovac Biotech Ltd. SVA, said Wednesday that a Phase 1/2 clinical trial of its COVID-19 vaccine in children and adolescents between the ages of 3 and 17 demonstrated that the shot is safe and produced a strong antibody response, according to a study published Monday in the medical journal The Lancet Infectious Diseases.  

   Vaccines are sensitive biological substances that can lose their potency and effectiveness if they are exposed to temperatures (heat and/or cold) outside of the required temperature range for the specific product (i.e., ultra-low or frozen temperatures) or when exposed to light. The vaccine had to be shipped at temperatures between -80°C and -60°C (-112°F and -76°F), could only be kept in a normal freezer at -20°C (-4°F) for two weeks, and unopened vials could only be stored at refrigerated temperatures of between 2-8°C for five days, before either being used or thrown away.

HENGKO vaccine CDC cold chain monitoring system is the key successful for the COVID-19 vaccine transportation and storage.

Environmental Condition Monitoring

HENGKO cold chain IoT solution enables logistic and supply chain companies to get real-time conditions on vaccines such as location, shipment status, temperature, and surroundings. The monitoring can ensure that the vaccine arrives at its ideal condition and if anything happens, precautions may already be planned.

Location Tracking

HENGKO IoT sensors communicating to the gateways enables pharmaceutical companies that are involved in the vaccines’ transport to keep track of the whereabouts of the vaccines. This will give them a heads up to schedule the next transport or the exact date the end-user company will be able to start using the vaccines.

Reduces Loss

The vaccines will travel via automobiles, trains, planes, and even boats or local transportation in some countries. At various transfer points, some will encounter delays caused by missed handoffs, product spoilage, or compliance issues. With automatic notification system, transporters can be notified of these unexpected delays or temperature excursions, and react before the vaccines are damaged.

Eliminates Time-Consuming Data Examination

When it comes to examining large amounts of data, IoT uses data analytics. This software helps in examining vaccine warehouses and queries large amounts of data in other departments as well. With data analytics, logistic and supply chain companies can get rapid results from large datasets and get the advantage of visualizing vaccine storage and shipment statistics.

As of August 14, 2021, China had administered about 1.85 billion doses of coronavirus COVID-19 vaccine, whereas about 4.7 billion doses of the vaccine had been applied worldwide.
