How did the Renaissance health/medicine breakthroughs impact and contribute to modern society?
The 15th-century Renaissance wasn’t that important; things began heating up in the 16th century, the beginning of the Early Modern Period (Pare and Vesalius belonged to that period), but it wasn’t until the 17th century that truly important research got underway. In other words, you need to separate the great medical Renaissance, which really began in the 16th-century/early Modern period, from the artistic/literary Renaissance, which can be dated to the early 15th century and even as far back as the early 14th. HOWEVER: it’s worth noting that such figures as Roger Bacon, probably operating under the influence of Arabic science, did exist well before the classic Renaissance period and the Early Modern era. But people like Bacon were unusual.
