Treatments get better. As we learn how the disease works, we know how to treat it better. This means that if you get sick now rather than at the beginning, you are much less likely to die.
Secondly: people are working on vaccines. If you can hold it until one is available, you might not have to get sick at all.
I work in vaccines and I don't believe any vaccine is even close to coming out. The products our company is working take about 10 years from start to final sale.
Its quite likely that the FDA will have to lower their standards to fast-track coronavirus vaccines. I am going to be very skeptical of their safety given that we don't have long-term data, especially with the newer unproven vaccine tech.
The vaccine is also still vapourware
