Unfortunately not true. Variants are genetically mutated strains incubated in hosts (that'd be us humans.) Variants mean COIVD is here for the long haul. Only vaccines will end the pandemic and shift COVID to be more endemic and localized.

Again, unfortunately, with so many misguided unvaccinated individuals there will be a lot of hosts available for new variants. And the pandemic continues... so, no, variants mean the pandemic will linger and continue.
