This copy may not be in its final form and may be updated. NEIL CAVUTO, FOX NEWS ANCHOR: How about some good news to kick off things, like herd immunity happening in a lot of parts of this country, including in San Francisco, where close to eight out of 10 residents older than 12 years old have already had at least one vaccination shot? It reads similarly in other cities, like Philadelphia, 67.4 percent have been vaccinated, in Denver, close to 70 percent, in San Diego, north of 65 percent, and, in New York City, more than 52 percent. And this is "Your World." And FOX on top of vaccinations that are surprisingly robust across a country that is rapidly leading the world in finally putting a spike in this horrific, horrific disease. Now, the implications of all of this are being weighed in the medical community, as well as the political community, as to how much longer term this means we get to, well, herd immunity, if we even need to get to that, technically, at the rate we're going. Let's go to Claudia Cowan following all of this in San Francisco -- Claudia. The City by the Bay is on the cusp of herd immunity, which means that the coronavirus is having trouble finding new hosts. The city is reporting that nearly 80 percent of teens and adults have been vaccinated with at least one dose against COVID-19, while 68 percent are fully vaccinated. The number of new cases is the lowest since the city shut down in March of 2020. And no one has died of COVID in over a month. San Francisco pushed people to get the shot while infections hospitalizations and death rates were low. Officials believe that made a world of difference. While there is some debate over what exactly constitutes herd immunity, one expert says the numbers here are among the best in the country. MONICA GANDHI, UNIVERSITY OF CALIFORNIA, SAN FRANCISCO: And there are places, like in the Bay Area, that are up to 76, 77 percent. So, we are doing great in terms of high vaccination rates, high immunity, low cases, low hospitalizations, low deaths, low test positivity rate.
