OCEANSIDE, Calif. (KGTV) — Oceanside lifeguards are warning beachgoers of multiple shark sighting off Oceanside Pier Friday.Lifeguards said they received multiple reports of an unknown species of shark, measuring about 12 feet in length, about 100 yards offshore on the south side of the pier just after 12:30 p.m.Two rescue vessels and a drone were sent out to the shark's last reported location, but no shark was located.RELATED: What to do if a shark attacks at San Diego County beachesThe waters have been cleared for swimmers and surfers for about 1 mile north and 1 mile south of the area, according to lifeguards.Waters will remain open Saturday, barring any other reported sightings.While shark sightings are rare along San Diego County's coastline, lifeguards are asking beachgoers to keep an eye out.RELATED: Beacon's Beach in Encinitas reopens following shark attackA 13-year-old boy was attacked by what is believed to have been a great white shark in September off the coast of Encinitas, just south.Keane Hayes was attacked while lobster diving at Beacon's Beach. Hayes suffered serious injuries to his upper body, but is expected to make a full recovery. 1212

OAKLAND, Calif. — Twitter says it will label or remove misleading claims that try to undermine public confidence in elections.This includes attempts at undermining people's faith in the process itself, such as false claims about election rigging or ballot tampering.It also includes misleading claims about the results of elections, like claiming victory before results have been certified, or inciting unlawful conduct to prevent a peaceful transfer of power or orderly succession.“The goal is to further protect against content that could suppress the vote and help stop the spread of harmful misinformation that could compromise the integrity of an election or other civic process,” wrote Twitter in a blog post.The policy goes into effect Sept. 17. It applies globally, not just to the U.S., which is holding presidential elections Nov. 3.Many people are expected to vote by mail, which is likely to delay election results.Twitter says its policy of labeling, rather than removing violating tweets from world leaders, will still apply.“We will not permit our service to be abused around civic processes, most importantly elections,” Twitter wrote. “Any attempt to do so — both foreign and domestic — will be met with strict enforcement of our rules, which are applied equally and judiciously for everyone.” 1318

One COVID-19 vaccine in development may be ready for review in December.Executives at Novavax say they are enrolling volunteers for a second phase of clinical trials now. The data should be ready for review within a few months.Phase 1 data showed the two-dose vaccine in healthy adults produced antibodies in all participants. Tenderness and pain were the most frequent local symptoms.When the first COVID-19 vaccines are approved, we won't know a whole lot about their safety.“We’re going to learn as we go along. There are numerous case studies in our experience where, as vaccines were rolled out, we were quite confident with the safety profile, but that evolves,” said Dr. Jon Andrus, adjunct professor at George Washington University’s Milken Institute School of Public Health.“I think that these vaccines will be safe in the sense that they won’t cause a serious or permanent adverse event when tested in 10,000, 15,000, 20,000people,” said Dr. Paul A. Offit with the Children’s Hospital of Philadelphia. “Hopefully, that will also be true in post approval when it’s tested and seen in 20 million, 30 million people.”Based on other vaccine history, a COVID-19 vaccine will likely produce some sort of adverse reaction. It could be minor typical injection site issues or something more serious.Back in the 1950s, the very first massive polio vaccination program was stopped because it paralyzed some children and killed a handful.In the 70s, the swine flu vaccine caused a very small amount of rare neurological cases. There are other issues like an allergic reaction or seizure.Still though, experts say vaccines are one of the greatest advances in modern medicine in preventing unnecessary deaths.“There is no better cost-effective intervention that medical science has to offer with the exception of safe water and sanitation, so when you look at our life expectancy, vaccines have been incredibly important,” said Andrus.The Vaccine Injury Litigation Clinic handles cases of vaccine-related injuries and deaths. They have on average just over 600 people per year receive payouts from the National Vaccine Injury Compensation Program. But they admit vaccine injuries are still rare compared to the overall numbers of administered vaccines every year.The Centers for Disease Control and Prevention (CDC) says for every 1 million doses of vaccines that were distributed, one person was compensated. 2413

OROVILLE, Calif. (AP) — Officials at the nation's tallest dam unleashed water down a rebuilt spillway Tuesday for the first time since it crumbled two years ago and drove hundreds of thousands of California residents from their homes over fears of catastrophic flooding.Water flowed down the spillway and into the Feather River as storms this week and melting snowpack are expected to swell the lake behind Oroville Dam in the foothills of the Sierra Nevada, said Molly White, principal engineer with the California Department of Water Resources.The spring storms follow a very wet winter that coated the mountains with thick snowpack, which state experts will coincidentally measure Tuesday to determine the outlook for California's water supplies. Heavy winter rain and snow has left the state drought-free for the first time since December 2011, experts say.The dam's main spillway "was designed and constructed using 21st century engineering practices and under the oversight and guidance from state and federal regulators and independent experts," Joel Ledesma, deputy director of the department's State Water Project, said in a statement."We spent the last two years restoring full functionality of the spillway. We expect it to run as designed," Ledesma said during a news conference.The original spillway on the 770-foot-high (235-meter) dam, which is 150 miles (241 kilometers) northeast of San Francisco, was built in the 1960s.In early 2017, storms drenched the state and the massive spillway broke apart as it carried heavy flows.Dam operators reduced the flow and allowed water to run down an emergency spillway — essentially a low area on the reservoir's rim — but the flow began eroding the earthen embankment that had never been used. Authorities suddenly had to order an evacuation of nearly 200,000 people living in communities downstream.The threat of a dam collapse that would unleash a torrent of water did not happen, however, and people were allowed to go home days later.In January 2018, an independent panel of dam safety experts released a nearly 600-page report that blamed the crisis on "long-term and systemic failures" by California dam managers and regulators to recognize inherent construction and design flaws in the dam.Repairs have cost .1 billion. California requested about 9 million from the Federal Emergency Management Agency for the fixes, but the federal government has rejected 6 million of those reimbursements. U.S. officials say the dam's upper gated spillway was damaged prior to the heavy rain two years ago.Local water agencies are already paying some of the repair costs, and they would cover anything not paid by the federal government. 2703
