Not enough vaccine will be available until 2021. Vaccinations are what will bring COVID under control. Vaccinations are more complicated than vaccines. Vaccinations take time. Two shot per person are required from the first two to be available and immunity takes 28 days after the second shots to be effective.

Some of the other 236 require only one vaccination but their availability depends on the results of the trials. For now there’s lots of hope, lots of hype and some luck involved as we move towards making us more safe.
