But vaccines are great tool.

They will be very helpful.

But the effect off the vaccine in increased providing some kind of immune barrier is still far off.

The things that must be done to prevent an increase, an uptick, a search, whatever you wanna call it are the public health measures, the distancing, the hand washing, the identifying every single case, identifying every single contact backwards, the people tripping in contact there but also forwards who led to you being infected.

Those things must be done with great, ever greater rigor to stop this intense transmission.
