During the last few months, many health experts have been talking about reaching “herd immunity” with the distribution of the COVID-19 vaccine. Over the Christmas weekend, Dr. Anthony Fauci said he estimates the country needs to reach 80-85% with the vaccine to attain herd immunity.Here’s what that means.Herd immunity is a concept used in discussions about vaccination, and signifies the threshold needed for a population as a whole to be protected from a virus.The World Health Organization clarifies that herd immunity, or population immunity, “is achieved by protecting people from a virus, not by exposing them to it.”The Mayo Clinic also describes the situation following the 1918 Spanish Flu outbreak. They say people who survived the pandemic were later immune to infection of the H1N1 flu, also referred to as swine flu.Health experts warn that relying on community infection to create herd immunity could be dangerous; there are questions about how long the antibodies created by infection protect against reinfection, and a high level of community infection could lead to overwhelmed medical facilities and a high number of deaths.When the threshold of herd immunity is reached, it means the vast majority of a population is vaccinated and has antibodies, thereby lowering the overall amount of community spread of the virus. It also means portions of the population who cannot get vaccinated are kept safer by the limited spread.What that threshold is varies depending on the virus and the efficacy of the vaccine.According to the WHO, herd immunity against the measles is reached with 95% vaccination, while herd immunity against polio is 80%.Dr. Fauci believes herd immunity for COVID-19 can be reached with around 85% of the population having antibodies. 1778

It's a sanctuary for his craft -- covered in silver and gold -- until thieves came in and took it away.The owner's daughter didn't want to show her face or give her name, but she walked 10News through surveillance video from February 28th.That's the day a group of nine people stole 0,000 worth of jewelry. Two of them were carrying babies."This group right here, the four people right here, are going to pull him all the way to this corner cause that’s the farthest away from the back room."Meanwhile, a woman in a black shirt and long skirt crawls on the floor to the safe in the back. For six minutes, cameras roll on her bragging everything in sight."She's getting all the bangles, she's getting all the earrings, chains, mostly the bangles, the bracelets the anklets," said the owner's daughter. She also took ,000 in cash."That’s the cash box and that’s where the detective was able to get her fingerprints as well. "The owner hit a panic button once he started getting suspicious but the alarm didn't go off.A family of immigrants who started with nothing -- now back to square one. "We're bringing everything that we have to help my father start from zero again." 1367

EL CAJON, Calif. (KGTV) - An El Cajon police officer's encounter with a group spray-painting graffiti ended in remarkable fashion early Wednesday morning.Sgt. Mike Murphy was on patrol around 2 a.m. when he got a radio call reporting people in dark clothing tagging along Heart Drive."Saw three males with dark clothing. Hit them with a spotlight and told them to have a seat, which they all did," said Sgt. Murphy.Two other patrol officers were called to the scene. The three men in their late 20s had spray paint under their nails, with fresh paint on the sidewalk and the wall of a business. Sgt. Murphy decided to take a closer look."I saw messages, not of hate, but of peace and love ... the peace sign and 'BLM.' Just had a discussion. 'You're not trying to say anything mean or hateful. Why did you choose a wall?' I understand the frustration of everything going on. Talked about, if this happened to their house, would they be upset? They apologized, and all agreed the avenue they chose was a wrong one. And they came up with, 'What if we fix this?' I said, 'I'd like to help you with that,'" said Sgt. Murphy.Sgt. Murphy, who says he had enough to make an arrest, decided to let them go and asked them meet at the same location that same evening, where he would help them clean up."Having them arrested, how is that going to help the message they're trying to put out? The vandalism would still be on the wall," said Murphy.At 7 p.m. Wednesday, the three men showed up with paint and rollers. Together with Sgt. Murphy, they painted over the graffiti."These men were true to their word. What better way to show not just how the department treats its citizens, but how the citizens treat our city. We all make mistakes, and sometimes we have to be given the opportunity to come back from a mistake," said Sgt. Murphy.The three men have decided to they will create a plywood art installation. Sgt. Murphy has promised to help them find a venue. 1961
