Why Dry Ice is needed for COVID Vaccine distribution
                     WHY DRY ICE IS 
NEEDED FOR 
COVID VACCINE 
DISTRIBUTION
INTRODUCTION
As the distribution of COVID-19 
vaccines starts rolling out across 
the United States this week, dry ice 
has become a hot commodity.

KEEPING THE 
TEMPERAMENTAL VACCINES
These super cold carbohydrate 
blockings are required to retain the 
temperamental vaccines at the 
correct temperature when you 
clock in at minus 109 degrees 
Fahrenheit.

DEMAND FOR FROZEN 
CARBON DIOXIDE 
The distinguished chemistry and 
biology professor, discussed how 
dry ice works as demand for frozen 
carbon dioxide increases because 
of COVID-19 vaccine distribution.

MANUFACTURING 
METHODS 
Dry ice is commonly produced by 
manufacturing methods such as 
the manufacture of petrol, ethanol, 
and even alcohol, as a by-product 
of carbon dioxide.

PROCESS
• Carbon dioxide doesn’t like to 
stay in liquid form for long, 
though. 
• To turn the liquid into ice, the 
liquid is placed in a 
depressurized chamber. 
• As the liquid naturally begins to 
convert to a gaseous state, the 
expansion of the liquid 
molecules into the air spurs a 
rapid decrease in temperature, 
causing the gas to freeze.

RECYCLE
• It’s a good thing that the carbon 
dioxide gets captured and 
recycled from these industrial 
processing sites.

WHY DRY ICE?
• Dry ice is convenient for 
shipping as it does not dissolve 
as the name indicates, which 
means there is no need for 
watery cleanup. 
• When it warms, the ice 
automatically skips the fluid 
stage and turns into smooth 
white wipes.

SAFETY WARNING 
• The smoke-like vapour may be 
enjoyable for specific effects, but 
in large concentrations and in 
confined spaces can be harmful.
• A new safety warning for crew 
members on board aircraft 
carrying elevated quantities of 
dry ice was released by the 
federal aviation authority.

COVID VACCINE 
DISTRIBUTION
• The relatively easy-to-make ice 
is more cost effective than 
alternative cooling methods for 
shipping the COVID-19 vaccines, 
which could include trucks 
equipped with generators used 
to power super freezers

COLD CHAIN 
CAPACITY
• The World Health Organization 
cites inadequate cold chain 
capacity as a major issue to 
vaccine distribution in 
developing economies. 
• In recent years, millions of doses 
of vaccines were lost due to cold 
chain failures. 
• Cold Jet’s Dry Ice Production Hub 
helps solve this issue.
