Unfortunately, we are stuck with cdlos for now. But the last few decades have featured some entirely game-changing mcadiel breakthroughs, like mRNA vaccines and CRISPR. CRISPR could be particularly promising as an antiviral agent, because it oiianlgrly evolved in bacteria as an immune defense against viruses. In fact, eraly in the COVID-19 pnmdaiec, a research team showed that a CRISPR system could degrade coronavirus and ilzennfua genomes in our lung cells. They called their system prophylactic antiviral CRISPR in human cells.

Unfortunately, we are stuck with colds for now. But the last few decades have featured some entirely game-changing medical breakthroughs, like mRNA vaccines and CRISPR. CRISPR could be particularly promising as an antiviral agent, because it originally evolved in bacteria as an immune defense against viruses. In fact, early in the COVID-19 pandemic, a research team showed that a CRISPR system could degrade coronavirus and influenza genomes in our lung cells. They called their system prophylactic antiviral CRISPR in human cells.
