Two people fully vaccinated against COVID-19 in Clark County have died after contracting rare “breakthrough cases” of the disease, local health officials report.

Almost one-third of Nevadans behind on getting their second shot of the COVID-19 vaccine are more than six weeks overdue, state health officials report.

Nevada is ranked 38th, with about 28 percent of the state fully vaccinated. The number with at least one shot is about 39 percent, but there have been problems getting people to get their second shot.

“I’ll probably wear a mask every flu season,” Danielle Sinay told her husband, noting that mask-wearing is customary in other parts of the world as is.

More than 122,000 Nevadans are behind on getting their second shot of the COVID-19 vaccine, state health officials reported Tuesday.

Out of the 1.6 million total COVID-19 vaccine doses given in the state, more than 57,000 doses were administered to people who didn’t give a Nevada address.

About one out of five Nevadans have been fully vaccinated from COVID-19, and nearly a third of the state’s population has received the first dose. It will take many more shots before the state reaches herd immunity — when the population gains protection through vaccination or natural immunity.

The COVID-19 pandemic has allowed scientists to continue important treatment research that could make a difference in how other deadly diseases are treated.
