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

During the start of the COVID-19 pandemic, many couples turned to Zoom and other virtual video platforms so they could still get married in front of loved ones. But as the pandemic continues, a lot of couples are now back to holding weddings in-person. With a little bit of distance between guests."I definitely think it’s going to be a thought on everybody’s mind whether: do you keep smaller numbers or do you have the large numbers you originally wanted and you just space the chairs? Do you have to have more tables and more people per table?" said Braden Sutton, a wedding planner, day-of coordinator and ordained minister with JBS Weddings and Events in Georgia. He, like other wedding planners across the country, saw soon-to-be wed couples panic when the pandemic first erupted in the spring."Of course they want the big wedding they planned but they don't know what to do because they don't want to cut people off of the list and they don't want to hurt anybody’s feelings," said Sutton.Six months into the pandemic, Sutton says more couples are turning to socially-distanced weddings, making accommodations at their venues and sometimes shortening their guest lists to still have an in-person celebration as safely as possible. "Because we’ve all seen a few things on social media about large numbers of COVID cases happening at weddings and other gatherings, nobody wants that to be their wedding. Definitely it's possible, just play it smart," said Sutton.Courtney Saxon and Kayla Zachery began planning their Georgia wedding nearly a year ago. "And honestly, in the beginning I think we both were like, 'Oh, everything will be fine by November we’re not going to have to worry about it,'" said Saxon. They soon realized, if they wanted to keep their wedding date, they'd need to make a few adjustments. Chairs at the ceremony will be spaced and fewer people will be seated at each table."Ideally what will happen is everyone will sit as a family unit. So if you live together, of course you're already around one another. We're just trying to keep everyone essentially around people they came with," said Saxon.They'll also have hand sanitizing stations at food tables and all entrances, plus a video live stream of the event for those guests who can't attend in person. While the wedding won't look exactly how they envisioned, the two have a positive outlook for their special day. "To me, the most important thing is that at the end of the day I get to marry my best friend. That's really all I care about. It doesn't matter if everything goes exactly as I hoped or we planned because no matter if you get married in a pandemic or not, things are bound and determined to go wrong," said Saxon."What do they have to do to make sure they're safe, guests are safe and another part is just the venue what they require," said Sutton. Sutton is also planning his own wedding which is supposed to take place in March. He believes most couples will be planning socially-distanced weddings through the end of 2021. 3029

EL CAJON (CNS) - A 21-year-old man accused of leading Border Patrol agents on a high-speed pursuit that ended with a crash on Interstate 8 in Boulevard, killing three of the suspected undocumented immigrants riding in the pickup and injuring seven others, was charged today with murder and other counts.Arraignment for Luis Alberto Virgen, a U.S. citizen who lives in Tijuana, was postponed until Dec. 18 so he can hire an attorney. He was charged with three counts each of second-degree murder and gross vehicular manslaughter, along with seven counts of reckless driving causing injury.Virgen, who is being held on million bail, faces up to 45 years to life in prison.Virgen allegedly sped off when federal officers tried to pull over the passenger-packed white Chevrolet Silverado he was driving near the Mexican border in eastern San Diego County shortly before 4:30 p.m. last Thursday, according to the California Highway Patrol.RELATED: Truck fleeing Border Patrol crashes in Boulevard; 3 killedWith the agents giving chase, Virgen entered Interstate 8 at Buckman Springs Road and fled to the east briefly before exiting at Ribbonwood Road and re-entering the freeway, this time headed west, the Border Patrol reported.After fleeing for several more miles, the suspect ran over a tire- flattening spike strip that agents had laid across the roadway in his path east of Crestwood Road, according to the federal agency.About a minute later, the Silverado -- occupied by a single passenger in the front and the rest unrestrained in the cargo bed -- veered off the interstate, went up a dirt embankment, became airborne, overturned and rolled back down the sloping roadside onto the freeway.Virgen was the only one in the truck wearing a seat belt at the time of the crash, and the others were ejected, CHP public-affairs Officer Travis Garrow said. Two of the male passengers and the sole female member of the group died at the scene of the crash.The names of the deceased were withheld pending family notification. Paramedics took Virgen and the surviving passengers to a hospital for treatment of moderate to serious injuries, Garrow said.About an hour after the fatal accident, Border Patrol personnel in the area came across another vehicle believed to have been involved in the apparent human-smuggling attempt and arrested a second man. The suspect's name was not released. 2393
