1. Hydroxy Chloroquine – Sulphate– In generic use although Chloroquine is used as antimalerial but the Hydroxy-
Chloroquine Sulphate can also be used to reduce the inflammation during the attack of Covid19 . Initially although the Drug was not getting approval from WHO but later on the drug is approved by WHO .
2. Lopinavir – Rinonavir Combination ( antiviral )– This combination is used against HIV in the treatment of AIDS can be
used against Covid infection crucially .But most efficient anti-viral against Covid19 – Remdesivir & Probably the final solution.This drug is specific to severe acute respiratory syndrome ( SARS-COV-2 ) .
3. Flavipiravir ( antiviral ) –This drug is used against the treatment of Japanese influenza is also used in India under the approval of DGCA , Govt of India , and Glen mark Pharmaceuticals Ltd . This drug is a cheaper one than Remdesivir itself . It can be also used in diabetic & Hypertension patients of Covid19 .
4. Rimantadine ( Amantadine ) – This drug is under trial but found efficient for elderly patient to treat respiratory
syndrome due to Covid19 .
5. Dexamethasone – A non anti-viral cortico-steroid used as life saving medicine ( LSM ) during severe Covid19 infection
. But it is non covid specific and also having other broad spectrum uses .
6 . Interferon – Beta – Ib – used for symptomatic Covid infections in combination with best Lopinavir – Ritonavir to
Remdesivir if necessary.7 .Remdesivir - The most effective antiviral against SARS-COV-2 used in wide spectrum in severe acute respiratory failure .

The second portion of the discussion contains vaccine developement . 

The vaccine developement incuding trial has already started  SII ( Pune ) are under trial of Phase2-3 trials . AstraZeneca - Oxford university , Cansino , Pfizer are trying under trial vaccine . As we are all aware that it is a long way to find out the ethical trial ( clinical efficacy  ) universally U.S.S.R has been under claim stage of Sputnik V final phase trial . We the common people are in good hope that the vaccination will get in success to stop such Spike Crown .Without the term immunity vaccination will not be effecrive to irradicate the viral infection .I

14.Social cociousness to be developed for better lifestyle more immune to us against viral attack or antibody generation . Immunity is surely surely correlated for vaccination or immunological biotechnology  of SARS-COV-2 infection . The above discussion links are showing a great effort of a potent Covid -vaccination with appropiate clinical safety and efficiacy trial . Bibliographic Discussions: ( For detail study of structure / SAR / Q – SAR / Pharmacogical / Biological activity &
