I understood your point regarding the idea to halt Corona virus reproducibility rate by developing a kind of mimicking virus.
Here, I would like to start this discussion by arising some questions:
1. If we could make such enemy virus (SARS COV-2Ev), Then what if the SARS CoV-2 virus again variate itself to make a coordination (synergistic relationship) with the Enemy Virus? (As the virus mutates itself in a minor way rapidly)
2. Second important things is to specify the way of mechanism through which the enemy Virus will work.
3. Will it help to cure the patient without any genetic side effects in a facile way I.e. without affecting the translation factory.
Developing enemy virus somewhere relates to developing a vector which could halt the Transcription and replication process of virus by directly causing obstacle in the polymerisation of ss-RNA of virus (+ve to -ve sense and -ve to +ve subgenomic ss-RNA). If such mechanism could be halted then some where we may go for the development of such enemy vector which could halt the viral mechanism in our body. (Mentioned conditions must be taken into the consideration).
