Watch for the NEXT COVID variant, it may NOT be covered by current vaccines.

 The link below shows the science behind fears of new and much more dangerous variants.

Short version

There are such massive numbers of people catching Delta (FL now has the most new COVID cases EVER in the state) that there are certain to be Epsilon, Zeta, Eta,Theta, etc. variants. One or more of them will almost certainly not be covered by the present vaccines.

We have great mRNA technology but new vaccines can't be developed until a new strain appears so there will be a minimum one month, more likely 6 month delay before emergency use authorization for a new vaccine.

One month would be the best case where congress would go along with the White House and courts permitting REAL public health requirements.

That won't happen so I am preparing for another lockdown.

On average 9 people will be infected by one person with Delta. Only 3 were infected by the first COVID.

BTW, most of PA is in the "safe" or moderate spread zone but most of the population is not is a safe zone and people move around, especially in summer and especially now.

The study in Nature essentially says that faster vaccinations reduce the chance of a more dangerous variant but easing of mask mandates, distancing, and other physical limitations (as opposed to vaccines) greatly increases the chance of a new, more deadly virus.

In other words EXACTLY what we are seeing in most of the country other than the northeast.
