It's going to be a long, long slog to get to herd immunity against COVID-19.
That's when so many people, for the novel virus about 70% - 80%, have been vaccinated that virus spreading becomes unlikely.
A recent poll from the University of Houston shows a third of us will likely refuse the vaccine.
Dr. Peter Hotez with the Baylor College of Medicine says we need 80 percent vaccinated to interrupt virus transmission. "When you start looking at numbers, 30 percent or 40 percent saying we're not going to take the vaccine, obviously we're not going to get there."
He says our only chance of defeating this virus is to get every adult vaccinated who can get vaccinated.
Hotez says new variants make this only more worrying.

He says they did a survey led by Texas A&M to look at vaccine hesitancy.
"The two most hesitant groups, one was the African American population, but even higher levels were in what we call Trump Voters. This is another component is that people on the far right are refusing to get vaccinated," Hotez said. "A lot of this comes from the health-freedom, medical-freedom movement that started in 2015. It started in Texas and Oklahoma. It led to the formation of organizations like Texans for Vaccine Choice that attempted to discredit vaccines."
Hotez says as a result, Texas has the largest population of kids being denied vaccines.
"It's deadly when you add on protests against masks and social distancing. This is contributing the the fact that now have 37,000, 38,000 Texans who have lost their lives. It's one of the worst tragedies to ever affect our state. And the numbers say it is going to go up to 50,55 thousand unless we can get our arms around it."
