Previous existence: Pathogenic influenza virus This life: The fighter flows in the resistance first
I am a first type H 1 N and a influenza vaccine. Begin from me " Pregnant with " It is " born " to get Get again to get legally " The registered permanent residence " Probably takes 45 days, the middle will pass every strict test, could provide protection for human security - --Imagine, succeed one neonate one first type the intersection of H and the intersection of 1 N and 1 influenza vaccine, above-mentioned passage this whether birth of it write. In the morning of the 8th, the reporter is in the department of Beijing located in Haidian District of Beijing revitalizes the factory buildings of the biologicals Co., Ltd., have viewed and emulated the production process of a influenza vaccine of first type H 1 N in the whole journey.

My previous existence: Drift in millennium

Previous existence of me, it is one that drift ten million annual small virus at the earth already. I am that a diameter have only 8 0 - 1 2 0 The small virus of nanometer, but my ancestor, through making a variation and recombinating constantly, having multiplied into a huge family, the ones that are divided into a lot are inferior type.

March of 2009 begin, I will appear in the human visual field gradually. The scientists began to name pig's influenza as me, renamed as new first type H 1 N 1st influenza again later. After the scientists separate me out, do not have pathogenic influenza virus a of P R 8 to breed with one together. In this course, I and P R 8 are recombinating constantly, the scientist recombinates and selects one in one from these and has P R 8 subject skeletons, but there is new poisonous one of an antigenic characteristic of H 1 and N at the same time. The assessment result of security shows, my toxicity after recombinating has already been reduced greatly, suitable for use in the production of vaccine. Then I broke with, and went on a way to oppose influenza virus the family from then on.

This life of mine: Break with the family

It must breed a large amount of influenza viruses at first to prepare a large amount of influenza vaccine. Through the exploration of nearly one hundred years, the scientist finds I am very suitable for allantois of chicken's embryo Reproduction.

The inoculating machine injects I of extraordinary small quantity into allantois of chicken's embryo accurately, then the chicken embryos of a truck of cars are put into aseptic, thermostatical hatching one, I am on in the fast reproduction of the inside silently, one changes two, two change four Three days later, I have already bred out much virus.

Hereafter, a large amount of Is were amalgamated together and transferred to and deactivated one, special one deactivated pharmaceuticals and was added into container, I lose consciousness slowly, sink and sleep while stired constantly About one week later, I wake from the nightmare, but find impressively that has already totally lost activity oneself, it is unable to make people cause a disease unable to breed and grow!

In a plurality of small rooms of the purified area, I cross some special sieves, pipelines many times, and been put in the high-speed centrifuge and has rotated for a long time, I have been concentrated gradually, and those impurity,etc. deactivated in pharmaceutical and egg has been deleted successively. Staff members have also added a special material which is named the cracked pharmaceutical to my side during this time, make me separate from an intact virus into chip, the impractical and some core on me may cause macromolecule protein and cracked pharmaceutical of the human bad reaction to be removed through purifying further, it can cause human body's immunoreactive surface antigen effective composition and internal antigenic albumen of the part to mainly keep. After sterilizing and filtering, I have a new identity: Virus original liquid. And then I am diluted according to certain water by injecting of proportion, and add right amount of salt and form the vaccine semi-manufactured goods.

But I it takes packaging and packaging procedure through being very strict to can become vaccine for the mankind to use directly yet. Because I am more fragile, need keeping in shade at a temperature of 2 - 8 . In the following two 3 weeks, I examine imprisoning two: Manufacturer and Nat'l Pharmaceutical & Biological Products Control Inst will collect a part at random I packed all to finish go on and then strict physical examination already. Examining and after the country examines again through enterprises, Nat'l Pharmaceutical & Biological Products Control Inst will award a certificate of competency to every batch of vaccine, it is legal that only that is to say I really obtained me at this time " The registered permanent residence " ,Can put into resisting it to the fight of influenza at once.
