‘Not Out of the Woods’: C.D.C. Issues Warning to the Unvaccinated

The director of the Centers for Disease Control and Prevention warned on Thursday that the United States was “not out of the woods yet” on the pandemic and was once again at a “pivotal point” as the highly infectious Delta variant ripped through unvaccinated communities. Just weeks after President Biden threw a Fourth of July party on the South Lawn of the White House to declare independence from the virus, the director, Dr. Rochelle P. Walensky, called the now dominant variant “one of the most infectious respiratory viruses” known to scientists.
