The timeline for developing a new drug or vaccine can vary significantly. If you already have data, the initial stages will be shorter.

In cases of emergent need or if you already know some information, such as with COVID-19 vaccines, timelines can be expedited.

This doesn't compromise patient safety but rather cuts down on bureaucratic delays. Generally, it takes about ten years from conception to completion, so I'd estimate the timeframe to be 10 to 15 years.
