SAN DIEGO (KGTV) -- Evidence left at a hit-and-run crash scene in Valencia Park could help police track down the driver responsible for the wreckage.At around 10:30 p.m. Sunday, San Diego police were called to a crash reported at Castana Street and San Jacinto Drive involving a fire hydrant.Officers arrived to find a sheared hydrant with a geyser spewing water about 50 feet in the air.While the vehicle in the crash was gone when officers got the scene, police found a bumper with a license plate that could help in the investigation. 545

SAN DIEGO (KGTV) - Health experts are weighing in after a local nurse tested positive for COVID-19 more than a week after receiving the Pfizer vaccine.In a Facebook message posted on December 18, Matthew W., an ER nurse at at two different local hospitals, talked about receiving the Pfizer vaccine that day. He told ABC 10News his arm was sore for a day but he suffered no other side effects.Six days later on Christmas Eve -- after working a shift in the COVID-19 unit -- he became sick. He got the chills and later came down with muscle aches and fatigue.The day after Christmas, he went to a drive-up hospital testing site and tested positive for COVID-19."It's not unexpected at all. If you work through the numbers, this is exactly what we’d expect to happen if someone was exposed," said Dr. Christian Ramers, an infectious disease specialist with Family Health Centers of San Diego. He serves on the clinical advisory panel for the county’s vaccine rollout.He points out, it is possible Matthew was infected before receiving the vaccine, as the incubation period may be as much as two weeks. Dr. Ramers says if Matthew did contract it after the vaccine, it’s still in line with what we know."We know from the vaccine clinical trials that it’s going to take about 10 to 14 days for you to start to develop protection from the vaccine," said Dr. Ramers.Dr. Ramers says he knows of several other local cases where health care workers became infected around the time they received the vaccine. He says all the cases illustrate the fact that results aren’t immediate. Even after you start receiving some protection, it won't be full protection."That first dose we think gives you somewhere around 50%, and you need that second dose to get up to 95%," said Dr. Ramers.Dr. Ramers says Matthew’s story also shows that even with vaccines, the pandemic isn’t going to turn around instantly."You hear heath practitioners being very optimistic about it being the beginning of the end, but it’s going to be a slow roll, weeks to months as we roll out the vaccine," said Dr. Ramers.He adds this case is a good reminder of why masks, handwashing, and other COVID protocols are important, even after receiving the vaccine.Matthew says he’s feeling better since his symptoms peaked on Christmas Day but still feels fatigued. 2323

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
