Pfizer requires a temperature of minus 70 degrees Celsius for its Covid-19 vaccine.


American pharmaceutical giant Pfizer, which sought approval from India's drug regulator Drugs Controller General of India ((DGCI) for emergency use authorization of its coronavirus vaccine, clarified storage concerns about its vaccine.

Pfizer requires a temperature of minus 70 degrees Celsius and experts have raised questions that India's existing cold storage facilities do not match these conditions. Pfizer told NDTV in a statement that it has “developed detailed logistical plans and tools to support effective vaccine transport, storage and temperature monitoring” and will be using different options for storage, ranging from temperature-controlled thermal shippers to refrigeration units that are commonly available in hospitals. It also said that the pricing of the vaccine will depend on the doses ordered and the advance commitments with the government.

The vaccine had reported an efficiency of 95 percent in the third stage of trials that were conducted abroad and is ready to be rolled out in the United Kingdom and Bahrain where it has received approvals for emergency use.
