We can now make the safest, most effective vaccines ever in 2 days. We're making huge advancements with mRNA. CRSPR is still a new technology that is being rapidly improved. Last years big biotech story was that we have more or less solved the protein folding problem, which effectively gives us strong predictive power. So yes, it's happening now. We're still in the early stages of it, but it is without a doubt happening. Edit: adding from a comment below, there are real world instances of lab grown tissues being transplanted into patients. That is also in the early stages, but has evidence of real world progress.
