Covid Vaccines: Need -70°C Cold Chain Storage, Which Is Not Ideal For India.
Its is a very difficult situation for India to maintain the cold chain storage in India which need -70°C temp. The reports suggest that leading experts have shown there concern regarding the issue of maintaining cold chain storage in India.
To maintain vaccines India needs to build storage facility throughout India. Based on weather condition and frequent power cut in rural even if the facility is built it becomes very much difficult to maintain vaccines at -70°C.
The former director general of Indian Council of Medical Research Dr N K Gangula told that covid vaccine which is being developed requires a very cold storage facility which will be very difficult even to most sophisticated countries like USA and Europe in transporting and storing. As reported by TOI.
In Lab when developed they have a well-maintained condition to store vaccines at -70°C to -80°C but this is not in case of hospitals.
This concern came when the report told the Pfizer vaccine which promises about 90% cure to covid requires to store at -70°C. Even Moderna Vaccine which requires cold storage of up to -20°C. So these vaccines do not work out good for Indian conditions nor to any developing nation's.
There is massive pre-order done from USA, UK and Japan which makes vaccines to be available only in 2021.
Pfizer and Moderna vaccines are mRNA messenger shots which trigger making of antibodies in the body. Since its mRNA messenger shots, this requires very cold -70°C to -20°C storage facility. Which is not a feasible option for India even thou Pfizer has announced to provide dry ice container which can store vaccines up to 10 days.
Experts say, there are many other vaccines getting ready which can be stored at -8°C to -2°C which can be beneficial for Indian conditions.
