Enter phase of later period experiment as the new coronal vaccine of research and development of multilateral pharmacy company, each country begins to prepare vaccinal plan. Nevertheless, success of vaccinal research and development is a long march of ten thousand lie only the first pace, potion vaccine, arrive from the lab final human body is vaccinal, still challenge all previous classics heavily. Even if solved large quantities of research and development, problems that estimate production, to it the fluctuation of be closely bound up swims the problem of industrial catenary also nots allow to ignore.
British reporter: Do not underestimate the challenge inside this, this needs a variety of differring to supply chain between run in coordination, it is vaccinal not only, still have ticket of stopper of vitreous bottle, rubber, paper, if among them any segment gives bit of issue, final vaccinal product will by defer.
In fact, be about to measure in new coronal vaccine during producing, lade vaccinal vitreous bottle already appeared in short supply evidence. Vaccine is chemical preparation, once produce chemical reaction with vitreous bottle, can be polluted, generate safe hidden danger. Because this is vaccinal,uses vitreous bottle is not average vitreous bottle, however in bottle of boracic silicon glass, its chemistry performance is steady, be able to bear or endure water, acid-proof. The country such as the United States, Europe all has forced in asking all inject preparation and biology preparation are used, boracic silicon glass is packed. Our country medicine is in at present with glasswork from give priority to with soda-lime glass and glass of low boracic silicon to in boracic silicon glass transfers. Up to by July, china already obtained vaccine of batch of 7 when enter clinical phase new coronals, vaccinal bottle material all was used in boracic silicon is officinal glass. ?
Hospital of accessary Mount Hua affects Shanghai Fudan University division director Zhang Wenhong: The crop of vaccinal vitreous bottle is more difficult than vaccine, vitreous bottle should have enough glass above all, still have enough manufacturer.
Vaccine of old new hat faces cold chain carriage difficulty lukewarm accuse final examination
Analytic orgnaization is forecasted, be like his have an inoculation 3 times, global permeability achieves new coronal vaccine 20% when, need vaccinal bottle 5 billion, global permeability is achieved 70% when, need vaccinal bottle near 16 billion. Inside global limits, almost all the biology medicine company that enlists new coronal vaccine to develop is queueing up bottle of scare buying vaccine. Public data shows, gave birth to a company by force to already bought 250 million vaccinal bottle only.
Vaccine is extremely sensitive to temperature, a research that the world defends an organization beforehand appraise, the whole world has every year amount to the vaccine of 50% to be wasted, because lack is lukewarm,this is greatly accuse to flow with whole cold chain thing. The company with two at present rapidder progress of brightness luck and Mo Dena research and development is MRNA, namely messenger ribonucleic acid is vaccinal.
Have Yan Ke's demand to temperature condition, the vaccine of brightness luck company must maintain the environment in 0 70 Celsius to fall, fall in the setting that still did not exceed establishment of cold ark of cold low temperature enoughly at present, many dry ice becomes replacement scheme. Brightness luck developed a kind of special constant temperature case, use dry ice to be able to store vaccine 10 days.
In city of Zhu Sai of American horse a place of strategic importance, mark and his group is intensifying producing dry ice for vaccinal manufacturer. In new coronal pneumonic epidemic situation restricts measure during, american gasoline slow down in demand, a few ethanol plants that produce carbon dioxide as by-product a future life are forced to shut, cause shortage of American carbon dioxide.
Intractable is, in international freightage, it is dangerous that dry ice is labelled article. Aviation of German Chinese Sha is warned, dry ice reduced a plane to carry vaccinal ability, dry ice amount is deposited to have restriction on machine, be in commonly 500 to 1000 kilograms of less than. ?
To let vaccine large-scale processing, safety is carried and can be distributed quickly, air-freight ability also cannot hinder sb. International aviation carriage association is presiding apparitor bright red Niyake call his global air-freight course of study " century mission " , according to international boat assist estimation, if according to the whole world vaccine of his potion new coronal comes to 7.5 billion person,calculate, the Boeing that needs 8000 sortie to be fully loaded with 747 cargo aircraft act instantly, ability satisfies transport power.
Additional, equality of the infrastructure of a few countries, wholesome water is more backward also, how to make sure vaccinal safety is carried and have an inoculation also is a difficult problem.
Is professor of British Birmingham college held in the palm than? Peter this: You can discover a few areas and country, the likelihood has 30 ％ to reach the medical treatment center of 40 ％ cannot power supply, in certain state, the medical treatment center that is less than 10 ％ possibly only deserves to have the freezer that can run normally.
New coronal vaccine has not appear on the market apiration of multilateral people have an inoculation drops
Although solved afore-mentioned heavy difficult problem, what vaccine should face finally is each have an inoculation person. The basis is newest civilian attune, with will compare in August, the apiration of new coronal vaccine spent the people have an inoculation of 15 countries to drop on average 4 percent, and the American that has apiration have an inoculation does not exceed 50% .
Eliminate misgive of people have an inoculation to defeat solution " last kilometer " difficult problem
Want to know, become only enough after much person is vaccinal, new coronal vaccine just can help people resist truly virus, this is meant, the last have an inoculation person more important than the first individual have an inoculation.
How to eliminate the inimical mentality with vaccinal to new coronal people, the likelihood becomes virus of conquer new coronal on this journey " last kilometer " .
