SAN DIEGO (KGTV) — Even though Americans could start getting vaccinated in days, experts say people who get the shot will still need to wear masks and practice social distancing until scientists can answer a key question: whether immunized people can continue to spread COVID-19.The clinical trials by Pfizer and Moderna showed the two vaccines were about 95 percent effective, but what that really means is they were 95 percent effective at preventing COVID-19 symptoms.The trials did not measure whether vaccinated volunteers got infected without showing symptoms.That means “it is possible and conceivable” that immunized individuals could still be silent spreaders, said Dr. Christian Ramers of Family Health Centers of San Diego. “You’re not going to get sick, but you still get an asymptomatic case, pass it on to your grandmother and kill her.”Both the Pfizer and Moderna vaccines are injected into the arm muscle to stimulate production of antibodies. From there, the antibodies can quickly get to the lungs to fend off severe infection. But experts say the antibodies may have less access to the nose and throat, the primary entry points for the virus.Some studies have suggested that people without symptoms can still have high enough levels of coronavirus in their nose to infect other people.“The vaccine is doing something to prevent disease. We don't really know yet if it prevents transmission,” said Dr. Ramers. “So we have to fall back on all those fundamental things like distancing, masking and washing hands.”Still, experts say there are encouraging clues that vaccinated people may be less contagious. A study in October found antibody levels in the blood were similar to levels in saliva.AstraZeneca had volunteers in its trial test themselves for signs of infection and reported there were fewer asymptomatic cases. However, the company has not yet provided details and its vaccine relies on different technology than Pfizer and Moderna’s mRNA candidates.Until we know more, doctors say vaccinated people will have to keep wearing masks -- potentially until there we achieve herd immunity.“There is modeling to suggest that it will be summer until we reach the point where there are enough people vaccinated that this curve of new cases really starts to go down,” Ramers said.There’s a chance we could get good news before then. Both Pfizer and Moderna say they’ll start testing their volunteers’ blood to reveal if they got infected after vaccination.Pfizer plans to examine a subset of its volunteers. Moderna said it will analyze blood from everyone in the trial.Moderna said it will take several weeks to produce results. 2656

SAN DIEGO (KGTV) - Hundreds attended a Juneteenth event in Balboa Park Friday.The event, 'Artists 4 Black Lives,' involved local artists commemorating Juneteenth through songs and performances."It was a way to celebrate Juneteenth, mourn our fallen black brothers and sisters, and amplify our black artists' voices," The event director, Eboni Muse, said.The holiday commemorates the day in 1865 when slaves in Texas learned they were free, two and a half years after the Emancipation Proclamation was issued."As black people, it is our Independence Day. We were not freed July 4," Muse said. "I personally think it's something we need to celebrate all the time."This year's Juneteenth celebration takes place at a time when the country is engaged in a national conversation about racial injustice and police reform. The atmosphere at Balboa Park was inviting and welcoming, drawing a diverse crowd."I'm hoping our artists will open the eyes of those who see us and really understand how we feel and how this has affected our people," Muse said. 1052

SAN DIEGO (KGTV) -- Despite skyrocketing prices, San Diego’s housing inventory is up in 2018, according to a new report by Trulia. The trend in America’s Finest City sits opposite the national trend, which is seeing a declining inventory. The national drop in inventory in the fourth quarter of 2018 was mainly driven by a drop in for-sale homes, however, in San Diego, the total for-sale inventory rose by more than 27 percent. San Diego’s trade-up inventory saw the largest increase at more than 46 percent. The report points out that, despite inventory gains in San Diego, prices continue to rise, outpacing wage growth. The trend places homeownership out of reach for many first-time homebuyers.

SAN DIEGO (KGTV) — High school athletes across San Diego County are waiting to find out if they’ll have a season this fall.The decision from California Interscholastic Federation is expected to come by July 20.In the meantime, some school districts, like Sweetwater Union High School District, have canceled summer workouts out of concern about the pandemic. Others, like Poway Unified and Grossmont Union, are allowing them with social distancing measures and new liability waivers specific to COVID-19.The CIF does not oversee summer practices, said San Diego Section President Joe Heinz, meaning it’s up to districts to decide whether to allow activities on their athletics fields and how to safely manage them.RELATED: CIAA, SIAC suspend fall sports, championship events due to COVID-19PUSD began allowing summer workouts for football, soccer, field hockey, and other sports in mid-June, after the district created its own set of safety measures from county, state, and other guidelines."We feel pretty comfortable about what it is that we’re doing," said Rancho Bernardo Athletic Director Peggy Brose. "So far so good."Teams have staggered practice times and specific entry points to avoid crossover, she said.Upon arrival to campus, staff check each athlete’s temperature and screen them for symptoms. Each athlete must bring hand sanitizer and their own water bottle. Players are required to wear masks until they reach designated areas.RELATED: California CCAA moving all sports to the springOn the field, students are kept in the same groups of 12 or less each day. For football, players are grouped by position. Summer football workouts are focused on strength and conditioning; contact and pads are already not allowed.Other safety measures vary by sport. In basketball and field hockey, for example, athletes have their own ball assigned to them to avoid sharing, Brose said.Although she acknowledged the school cannot entirely eliminate the risk of transmission, she said supervised activities at school may be inherently safer than unsupervised ones.“We can control them when we have them,” said Brose. “What we can’t control is what they do on their own.”Mt. Carmel High School Football Coach John Anderson said the response from parents in his program has been clear.RELATED: Big Ten Conference limits fall sports to conference-only matches, athletic scholarships still honored“We have 20 more kids this summer than last summer,” he said. “So parents are really encouraging their kids to come out and play.”But not all. 10News spoke with a Poway Unified parent who kept his son out of summer athletics out of concern about the virus.“How can they not be infecting one another?” he said.The parent, who asked to have his name withheld from the story, provided photos of a workout on a football field with what he considered poor social distancing.“While they’re doing the calisthenics in warmups they are trying to keep six feet apart, they observe the distancing,” he said. “But when they’re running, they start bunching up.”The parent said he is a strong supporter of high school sports, but said the risk of transmission, particularly when athletes are breathing heavily, is too great.“COVID has been hard on everyone, particularly young people, but the good of the community should come first,” he added.He was concerned after Poway Unified required parents to sign a new waiver, releasing the school from all claims related to COVID-19 and acknowledging that participation in summer workouts could lead to transmission of the virus that could spread to an athlete’s parents or family members, potentially causing death.Grossmont Union High School District also added a mention of COVID-19 in its liability waiver.“Will the younger people die? Probably not,” said the parent. “But they’re going to go back and continue to spread it to their parents and grandparents who are at greater risk.”That risk has prompted other districts, like the Sweetwater Union High School District, to ban summer practices entirely.“We continue to be very concerned about the increases of cases in our communities, at a rate significantly higher than in other communities within the county,” Chief Compliance Officer Vernon Moore wrote in a letter to parents.Citing updated guidance from the state, Orange County banned all youth sports practices as of this week, but for now, San Diego County says it will allow them.“I think it can’t do enough for their mental health, their self-esteem,” said Coach Anderson. “Being cooped up in their houses for the last few months, to get out, run around and be active is really beneficial to their mind and body.” 4659
