Nearly 12000 COVID-19 vaccines in USA failed due to cooling system failure
Nearly 12000 COVID-19 vaccines in USA failed due to cooling system failure. According to Fox News, nearly 12,000 doses of Moderna’s COVID-19 vaccine in Michigan, the United States, became invalid due to improper handling during transportation, resulting in too low storage temperature.
Moderna vaccine needs to be stored and transported at minus 20 degrees Celsius, and the temperature must not be lower than minus 40 degrees Celsius, otherwise it will fail. It can be stored under refrigeration at a temperature of 2 to 8 degrees Celsius for 30 days, and once thawed, it cannot be frozen again.
The Michigan Department of Health and Human Services issued a statement stating that the temperature control system for a total of 11,900 vaccine doses in 21 batches shipped on January 17 failed and the temperature was below safety standards. After investigation, the gel packaging used to control the temperature during transportation has defects, causing the temperature to run out of control.
Since then, Moderna repackaged and sent replacement doses on the 18th and 19th, and 6 batches of vaccines were put on hold for inspection.
Affected by this error, the work of at least six vaccine supply points was postponed.
This is not the first time Moderna has a problem. This week, during a clinic in San Diego, California, during the vaccination of the company’s vaccine, 10 people experienced adverse reactions and received emergency treatment. A total of 330,000 doses of vaccinations across the state of California have been suspended, and agencies are cooperating to investigate the cause of adverse reactions.
Michigan Governor Gretchen Whitmer said at the press conference that we are in competition with the virus and every dose of vaccine is important. This is frustrating news, but beyond control. Currently, the promotion of vaccines is very unsuccessful, and the supply of the entire state is far from insufficient. We can only get 60,000 doses of vaccine each week, instead of the 300,000 previously promised.
Whitmer said that Michigan originally planned to vaccinate 50,000 residents every day and plans to achieve 70% of the population in 6 months. But according to the current slow progress, it means that it will take more than two years to achieve 70% vaccine coverage.
