Protests against mandated COVID-19 vaccines pop up across US
Pushback is happening over vaccine requirements and mask mandates.
The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 615,000 Americans have died from COVID-19 and over 4.2 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 58.4% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
The CDC last week, citing new science on the transmissibility of the delta variant, changed its mask guidance to now recommend everyone in areas with substantial or high levels of transmission -- vaccinated or not -- wear a face covering in public, indoor settings.

Prior COVID infection followed by vaccination more protective than infection alone: CDC
Being vaccinated after having had COVID-19 offers far better protection than prior infection alone, according to a study the Centers for Disease Control and Prevention released Friday.
The study, which appeared in the agency's Morbidity and Mortality Weekly Report, examined Kentucky residents who had previously had COVID-19. Some chose to get vaccinated, while others didn't. The result: Those who skipped the vaccine were more than twice as likely to be reinfected compared to those who were vaccinated.
"If you have had COVID-19 before, please still get vaccinated," said Dr. Rochelle Walensky, the CDC's director. "Getting the vaccine is the best way to protect yourself and others around you, especially as the more contagious delta variant spreads around the country."
