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) — As grocery stores work to fill consumer demand created by the coronavirus pandemic, several San Diego stores are hiring.Albertsons and Vons locations in the San Diego area are working to fill about 1,000 jobs, a spokesperson told 10News. So far, more than 200 of the positions have been filled and locations are actively conducting interviews. "We have a high volume of applications and still have many more jobs to fill," the spokesperson said.RELATED: Will you qualify for a ,200 COVID-19 stimulus check?Parent company Albertsons Companies is in the process of hiring about 30,000 new employees to respond to the demand. Under the federal government, supermarkets are considered "critical infrastructure" and are required to operate during the crisis.The openings are welcomed relief for not only grocery employees, but those seeking work as well.Since the COVID-19 pandemic created havoc on the economy, California has seen unemployment claims skyrocket. For the week ending March 21, the state saw a 363 percent increase in claims year-over-year:Week ending March 7, 2020: 48,385Week ending March 14, 2020: 57,606Week ending March 21, 2020: 186,809“We know there are many Californians who are really struggling to provide for their families because of the massive economic impact created by the Coronavirus,” said EDD Director Sharon Hilliard. “Unemployment benefits provide critical financial support and the EDD is employing all means necessary to get benefit payments out to those in need.”RELATED: 3.3 million seek US jobless aid, nearly 5 times earlier highAlbertsons Companies says it is partnering with a handful of major companies to offer their furlough workers part-time jobs at supermarkets as well.“The most valuable asset and the core of any business is people, and we are working hard with many Human Resource teams across a variety of businesses who are actively defining next steps for their employees,” said Albertsons Companies President and CEO Vivek Sankaran. “So many businesses in the hospitality and retail sectors are scaling back hours or temporarily closing as their customers remain home and adhere to shelter-in-place orders. We are grateful to be a resource to help fill a critical need in our own business and take care of people who want to continue working during this time of national emergency.” 2362

  

SAN DIEGO (KGTV) -- California’s new gig economy law was meant to help rideshare drivers and other freelance workers get better benefits, but some critics say it’s threatening the spirit of Christmas itself.Those critics are mall Santas, who have traditionally been hired as independent contractors through third-party bookers or employment agencies.Under Assembly Bill 5, authored by Assemblywoman Lorena Gonzalez (D-San Diego), those workers must be reclassified as employees with insurance and other benefits.“Lorena Gonzalez, she might kill all the Santas. She might kill the Easter Bunnies,” said Steve Schafer, the president of the San Diego chapter of the Fraternal Order of Real Bearded Santas.Some Santas warn that bookers may go to great lengths to avoid paying employee benefits. “I don't know how someone can justify this,” said Jerry Tamburino, a Santa who has worked for more than a decade at a large commercial store.Tamburino said his agent notified him Tuesday that she would replace him and other Santas at a chain of California retail stores with out-of-state St. Nicks.“That's what [the booker is] being forced to do to address -- or evade -- or stay in business with this stupid law,” he said.Bringing in out-of-state workers to skirt AB-5 would violate California law, since labor laws apply to anyone performing work in the state, said Gonzalez’ office. But Tamburino said it would be hard for regulators to enforce.Malls and stores could hire Santas directly as independent contractors, Gonzalez’ office noted, since that kind of relationship passes AB-5’s three-pronged test.To do so, Tamburino said he would have to form his own LLC and said he doesn’t have the experience to run his own business.Tamburino said he would begin reaching out to other Santa-booking agencies in hopes they will hire him as an employee, but there’s a lot at stake: he receives about half of his annual income from Santa jobs. 1938

  

SAN DIEGO (KGTV) — As temperatures warm up, there is some early research suggesting air conditioning units could increase the risk of spreading COVID-19.One team of researchers swabbed several kinds of air conditioning units and found traces of the virus on one out of every four samples.One of the authors, University of Oregon professor Dr. Kevin Van Den Wymelenberg, said the research “does give us some pause.”Air conditioning units bring in little outside air, particularly when temperatures are very hot, posing a risk that viral particles could be recirculated into rooms, Van Den Wymelenberg said.However, just because the study found traces of the virus in A/C units, it doesn’t prove people can actually get sick from the contaminated air because it’s not yet clear how many viral particles it takes to infect someone, he noted.“Nobody knows what that minimum threshold is so we need to take as many precautions as possible,” he said.Dr. Edward Nardell, a professor in the Departments of Environmental Health and Immunology and Infectious Diseases at the Harvard T.H. Chan School of Public Health, said air conditioning units can generate air currents that can carry large particles farther, similar to what researchers found contributed to the spread of the novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China."You are not socially distanced as much, but you're re-breathing the same air that someone else just exhaled," Nardell said. "We call it rebreathed air fraction, and if someone is infectious, often asymptomatic, you're going to be rebreathing their small particles."This week, a group of 239 scientists from 32 countries asked the World Health Organization to update its COVID-19 guidance to reflect that the virus is airborne.On Thursday, the WHO released updated guidance acknowledging that airborne transmission can’t be ruled out, but stopped short of confirming that the virus spreads through the air.Instead, the WHO said the virus primarily spreads through droplet transmission, where larger particles come out of an infected person’s mouth, then fall quickly to the ground or onto surfaces. In airborne transmission, the particles stay floating for a long time.“I think they’re underweighting the importance of this airborne route based on the best available information,” said UC Berkeley Professor Emeritus William Nazaroff, one of the signatories of the letter to the WHO.He said in a poorly ventilated room, particles might linger for 30 minutes to an hour.Scientists say one of the best ways to protect yourself is to open windows, to increase the circulation of fresh air.Scientists say upgraded air filters in AC units and standalone air purifiers could also help.Germicidal lamps may also be effective, Nardell said. The technology is almost 100 years old, and has been proven effective in protecting against tuberculosis infection.The lamps, which shine ultraviolet light, are set up to shine horizontally, high up in the room to kill floating pathogens.Nardell said the technology can be deployed cheaply and easily in a number of settings.Additional reporting by Lauren Rozyla at WFTS 3159
