Brazil Does Not Have Deep Freezers that Could Store Pfizer Covid-19 Vaccine
Even the existing structure for vaccines that require higher temperatures is uneven in the country

The good results of the completed tests of the vaccine from Pfizer and BioNTech against Covid-19, announced this Wednesday (18), will face an unprecedented challenge: the storage and distribution of a vaccine immunization with two doses in an interval of 21 days at -70 ° Ç.
In Brazil, there are currently no deep-freezers for this in the country's Brazilian National Immunization Program.
Today, the standard for vaccine maintenance in the world is done in refrigerators, with temperatures ranging between 2° C and 8° C. That's what we find in homemade refrigerators.
Immunizations against yellow fever and polio require storage at lower temperatures (-15ºC to -25ºC) in equipment such as scientific freezers. Before being administered, the two vaccines migrate to the "standard" temperature of the refrigerators, 2° C and 8° C, where they can stay for up to a month.
