This is only possible by systematic usage of the following NCD vaccines: asplin/F strain, followed by Lasota, R2B AND THEN AN INACTIVATED/killed NCD vaccine.
In the control of NCD, local immunity, cell mediated immunity and humoral immunity play a role. R2B and komorov strains are of the same category, both are mesogenic strains.
I have heard of lasota and komorov, but which one is asplin/f strain, r2b and killed vaccine?
