Washington Post -  Coronavirus infections are climbing again, marking another summer wave as children go back to school.  But this uptick arrives with an added layer of uncertainty because it’s unclear when and which Americans can receive updated vaccines this fall.

Daniel R. Kuritzkes, chief of the division of infectious diseases at Brigham and Women’s Hospital in Boston, said the current rise looks similar to seasonal bumps in previous years and is not driving a surge in severe illness.

This is the new rhythm of covid waves. Many people are getting sick — some feeling lousy — especially after returning from vacation and conferences. Most probably won’t even know it’s covid because the symptoms can be indistinguishable from a cold or other respiratory bug. Yet hospitals are no longer flooded with patients because immune systems are much better trained to fight the virus five years after it arrived.
