Cuba's "magic drug" to conquer pneumonia key?

recently, The Economist listed five drugs that have been tested for potential to treat the pneumonia. In both sets of medicines, there is Cuban "a2b interferon" (a2b).Before most developing countries entered, Cuba had set up an interdisciplinary bio-professional forum in 1981, just two years later than the world's first biotechnology company, Genetech in San Francisco. At the time, it was a coincidence that two things were going hand in hand.First, dengue fever began sporadically in central, western and eastern Cuba at the end of 1980, and was officially confirmed in May, with more than 244,000 people infected by the end of October, an increase of 1,100 cases a day at peak times and 180 deaths before and after. The second is Cuba's own efforts and luck. In March 1981, six Cubans went to Finland to study with a2b-related technology, and the country's doctors refused to apply for patents on their technology, insisting that it be made available to all, including Cubans. These Cubans only took 12 days in the Thousand Lakes countries, returned home 45 days later, successfully self-extracted a2b, the medical community called "magic medicine", not only successful treatment, and under extensive vaccination, dengue fever has never been prevalent in the island nation, can be called a model of the Caribbean region.In addition to dengue fever, the efficacy of a2b has been recognized for diseases such as hepatitis B and C, shingles and HIV-AIDS. After the establishment of Changchun Haibel Biotechnology Co., Ltd. in 2003, the Sino-Ancient joint venture launched a2b injection in 2008 and was quickly recognized as "very high reputation". Today, the medical community believes that a2b should be effective in treating viruses like COVID-19 to prevent complications of worsening and death.That year's magic drug a2b, this time can be magical again, it remains to be seen. However , in addition to neighbouring Jamaica , many Latin American countries such as Panama , Venezuela and Chile have imported the product to Cuba , and even Brazil , which is unfriendly to Havana and last year expelled Cuban doctors , has asked Cuba to send doctors because of the outbreak . Further a south, South Korea and Germany have also used a2b, with relatively low deaths of 84 and 26 of its more than 8,000 and 9,000 patients, respectively.Cuba also sent a team of medical personnel to help Italy with mainland experts, and the British cruise ship Bremer was eventually taken to its port by Cuba after eating a large number of closed doors, with more than 1,000 passengers, including 45 confirmed or quarantined persons.
