The universal vaccine is a trick that has traveled all over the world, but it is so easy. But the goal still has to be there, in case it is achieved!
There are currently two options for the idea of universal vaccines: A plan is to find the part of the pathogen that is inseparable from its origin and make it into a vaccine; plan B is to integrate the existing various variants or types together to make a vaccine.
Scheme A is concise and straightforward, one-hit fatal, and if it is realized, it can be done once and for all. On the universal influenza vaccine, Protocol A has been tried for many years, but it has not been going well. The generic pneumococcal vaccine currently uses the B scheme, which integrates more and more pathogenic pneumococcal types (7 valent→ 10 valence→ 13 valence→ 20 valence→23 valence), but also exploring the use of scheme A in order to overcome the major shortcomings of scheme B.
The essence of Scheme B is to stack arhats, simple and rough, but the luohan and the arhat will affect each other, may involve the whole body, research and development and preparation costs are getting higher and higher.
In reality, there are many successful cases of Scheme B, such as the cerebral polyvalent vaccine, the pneumococcal polyvalent vaccine, and the cervical cancer polyvalent vaccine. If the coronavirus vaccine is to be successful, the first consideration should also be the B plan, and the A plan should also be studied, but success can be encountered and not sought.
The following report, reproduced from the "Reference News", is the progress of the introduction of the B plan for the universal vaccine for the coronavirus.
