Cold Chain in Vaccine Rollout: from COVID-19 Pandemic Perspective
It had been a year since the Novel Corona Virus (COVID-19) outbreak happened. Scientists had continuously strived to invent a vaccine, and finally, many pharmaceutical companies are coming up with their interventions. With the few of the clinical trials coming to a climax, the Pharma companies and Governments are pondering on the distribution of vaccines to billions of people and their supply chain management which poses as one of the major challenges. From the time of manufacture till distribution, vaccines must be continuously stored in a limited temperature range, according to the type of vaccine. Different vaccines have different storage conditions like ambient, freeze-sensitive or frozen. Since vaccines are parenteral, optimal temperature and storage are to be taken care of to prevent any leakage and decrease in the efficacy of the vaccine. In order to tackle this challenge, WHO has recommended certain ‘cold chain’ principles to manage the vaccine roll out? A temperature-controll
