Some scientists believe that thanks to Delta, the R0 value for Covid could now be as high as 5-8, much higher than well known winter viruses (not as high though as chickenpox and measles, but there's different immunity levels and behaviour there). If this is true, I don't think all the caution in the world will stop covid spreading, and the best we can hope for is enough immunity builds up through the various channels to naturally bring about a peak. The situation in India with delta was dire, but even there the extremely high peak quickly dropped off, and looking at a graph of it the wave lasted around 3 months, much shorter than its first wave and our winter wave. As unfortunate as this can be, nature is better than us.
