SAN DIEGO (KGTV) — As Pfizer’s COVID-19 vaccine begins circulating, there is another big logistical challenge ahead: reminding people to get the second dose.Both vaccines developed by Pfizer and Moderna require two doses spaced several weeks apart. People who get immunized often feel fatigue or soreness shortly after the shot and may experience fever, particularly after the second dose, according to clinical trial data.Doctors say those immediate, short-term side effects are a positive sign the immune system is revving up production.The side effects are similar to that of the shingles vaccine. But studies show about 20 percent of the people who get the shingles vaccine skip the second dose.Experts say if that happens with the COVID vaccines, there could be consequences.The worst-case-scenario is that skipping the second shot could allow the virus to spread and mutate, and potentially build resistance to the vaccines, according to Penn State University biologist David Kennedy.That outcome is considered unlikely, but the World Health Organization announced Monday it detected a new variation of the virus in England, showing the virus is already mutating without the evolution pressure of a mass vaccine program.“Does this make the virus more serious? Does it allow the virus to transmit more easily? Does it interfere with diagnostics? Would it interfere with vaccine effectiveness? These are questions. None of these questions have been addressed yet,” said Dr. Michael Ryan, director of the WHO Health Emergencies Program.When administered in two doses, Pfizer’s vaccine is 95 percent effective at preventing COVID-19 symptoms. The FDA’s review showed the vaccine could be up to 52 percent effective after a single dose, but the data was limited.“I think you could probably say you’re going to have short-lived but incomplete protection,” said vaccine expert Dr. Paul Offit. “Protection from disease but possibly not asymptomatic shedding.”It remains unclear whether people who are fully immunized against the virus can still spread it to others asymptomatically but someone who is only partially immunized may be especially prone to silent spread, according to Offit.When Americans roll up their sleeves to get the COVID-19 vaccine, they’ll get a 4 by 6 inch index card from the CDC noting which brand they got, the lot number, and when they’re due for the second shot.People who get Pfizer’s vaccine need to get a second shot 21 days later. People who get Moderna’s need to wait 28 days for round two.The CDC is encouraging people to photograph their card with their cell phone as a backup, because beyond the index card, the logistics of reminding people about their second dose will vary by state and healthcare provider.In California’s draft vaccination plan from October, the state said it was exploring ways to "systematically text, email, and/or auto-call individuals when their second dose is needed." The California Department of Public Health did not immediately respond to a request for comment about its latest plans.Much of the work may fall to the healthcare providers who administer the shots. Although the vaccine will be free for individuals, the government is paying providers for every first dose they give and for every second dose, a way to incentivize providers to keep close tabs on patients.However, only about 25 percent of the nation’s vaccination providers have systems that can send automated reminders, according to L.J Tan, the chief strategy officer of the Immunization Action Coalition. 3552

SAN DIEGO (KGTV) - Community leaders are reacting to this week's move by state lawmakers to let voters decide in November whether to reinstate affirmative action.“It’s been a long, hard road and now we can actually see some light at the end of the tunnel,” said San Diego NAACP President Francine Maxwell on Thursday afternoon. It follows Wednesday's news that California lawmakers approved a proposal to repeal the 25-year-old law that bans looking at race, sex, ethnicity, color or national origin in college admissions, contracting and public employment.“The NAACP San Diego branch is elated that it was a 30-10 vote. Two-thirds majority said that things have to change and we're headed to November,” she added.Assemblymember Shirley Weber (D-San Diego) authored the bill and asked for support on ACA 5, which lets voters decide whether to reinstate affirmative action by repealing Prop 209.“The ongoing pandemic as well as recent tragedies of police violence is forcing Californians to acknowledge the deep-seated inequality and far-reaching institutional failures that show that race and gender still matters,” she told her colleagues this week.“African Americans have been at the bottom for over 401 years. Affirmative action was an opportunity so they could open the door to walk into colleges, to [have] the opportunity of economics, to change the narrative of their family,” Maxwell told ABC10 News.Republican Assembly candidate June Cutter from San Diego opposes the return of affirmative action. Thursday, she told ABC10 News, “It is a band-aid put at the end of the problem rather than trying to find a solution to the disparity that I absolutely acknowledge exists and instead of trying to fix it at the starting line we're trying to fix it at the finish line and that's what I have a real problem with.”Cutter said she believes real change needs to happen earlier through the course of opportunities in K -12 education within under-served and under-privileged communities.Assemblymember Weber was unavailable for an interview on Thursday but her office sent ABC10 News the following statement.“The fate of Prop. 209 will now be in the hands of voters on November 3rd. While it was sold as a civil rights law when it passed in 1996, Proposition 209 has cost women- and minority-owned businesses .1 billion each year, perpetuated a wage gap wherein women make 80 cents on every dollar made by men, and allowed discriminatory hiring and contracting practices to continue unhindered. Far from being colorblind, the bill has set up barriers to women and minorities to share in the economic life of California. Proposition 209 has hindered public policy, thwarted opportunity and maintained economic disparity long enough. It’s time to give voters a chance to right this wrong.” 2796

SAN DIEGO (KGTV) - As the election nears, millions of people will be glued to smartphones and computer screens, scrolling through social media for instant information.But platforms like Twitter and Facebook may not be the best sources for information."The way the algorithms work, they promote stuff that gets a lot of reaction or a lot of engagement," says University of San Diego Assistant Professor Colin Campbell. "The systems are designed to try to show you stuff that they think is going to actually make you excited or make you react in some way. And as a result, that tends to be the more polarizing stuff."But both sites have taken steps in 2020 to safeguard against misinformation.In a lengthy blog post about their election protocols, Twitter called their role in the election "critical," saying that people should "use Twitter respectfully and to recognize our collective responsibility to the electorate to guarantee a safe, fair, and legitimate democratic process."They adjusted their "Civic Integrity Policy" so that only verified and official accounts can tweet about election results. They're also imposing stricter punishments for Tweets calling for election interference or violence.Twitter also made changes to the way people interact with links posted on their platform.They've added warnings to misleading tweets and direct people to more credible information if they engage with a misleading post.They also now ask people to click on a link before Retweeting it and encourage "Quote Tweeting," where people can comment on what they're sharing instead of just reposting the original Tweet.Twitter also changed the format of its Trending section, adding context to topics and hashtags.Facebook, meanwhile, put a lot of effort into helping people vote. Their Voter Information Center helped 4.4 million people register to vote in 2020.They also banned all ads related to the election, politics, or other social issues during the entire month leading up to the election.To help keep misinformation from spreading, Facebook says they removed 120,000 posts from March through September for violating their Voter Interference Policies. They also issued 150 million warnings for content that was flagged as misleading by independent fact-checkers.Campbell says both platforms are a lot more reliable now than they were in 2016, but could still have done more. He believes it's because they didn't want to face criticism over censorship."From a pragmatic perspective, they probably don't want to get involved in the challenges of trying to go through and censor or decide what kind of stuff they want to have on the site," says Campbell.Even with all the changes, he says users still need to scroll with skepticism and filter the content they chose to engage with."I think it's very important that we're all vigilant," he says. "We need to report stuff that we see that isn't true or things that we think might be inflammatory or have a negative effect in some way."He also says people should curate their social media feeds to follow trusted news sources and official accounts for election information.For more for election information in San Diego, be sure to look at the Election 2020 section of 10news.com. 3232

SAN DIEGO (KGTV) - As San Diego County's back country communities brace for the prospect of losing power, political leaders are starting to take aim at the idea of pulling the plug on them.San Diego Gas and Electric has notified upwards of 30,000 customers that it could cut their power Thursday if it deems necessary to prevent a wildfire. At a news conference in San Diego Wednesday, Gov. Gavin Newsom praised SDG&E as a leader in wildfire prevention, but expressed frustration at the situation. He directed most of his anger toward Pacific Gas and Electric, which has cut off power to hundreds of thousands of customers in Northern California to prevent its equipment from starting wildfires. "And by the way, I'm outraged because it didn’t need to happen," said Newsom.RELATED: SDG&E prepares for Public Safety Power Shutoff as Santa Ana winds approachZoraya Griffin, a spokeswoman for SDG&E, said turning off power is a last resort. She said the utility is in communication with fire departments and has crews and arborists deployed across the county. SDG&E is also staffing the Emergency Operations Center at its headquarters in Kearny Mesa to monitor conditions. "The population here in San Diego really need to be mindful that this is about their safety at the end of the day," Griffin said. SDG&E began the practice of cutting power in 2013. That's a big change from the 2007 wildfires, which investigators say happened as a result of SDG&E equipment. RELATED: MAP: San Diego County communities affected by planned outages"After the wildfires of 2007, we started implementing what became the largest utility weather network in the world," said Brian D'Agostino, SDG&E's director of fire science, "We hired a team of meteorologists and we started to understand Santa Ana winds a lot better."While the governor praised SDG&E, other officials took a much different stance. County Supervisor Dianne Jacob derided the utility, saying cutting power creates safety risks for seniors, those dependent on medical devices, and households that need to electrically pump well water. "As always, SDG&E is putting itself first and looking to cover its liability rear end," she said in a statement. "Instead of taking the easy way out and pulling the plug on vulnerable communities, SDG&E should redouble its efforts to fully harden power lines and other infrastructure.”SDG&E is required to give customers 48 hours notice of a shut off. 2480
