SAN DIEGO (KGTV) — Currently, there are five vaccines that kids in California must get to attend school, and a lot of parents are wondering if the eventual COVID-19 vaccine will be added to that list.A website run by the California Department of Public Health seems to suggest that a change to the state’s immunization requirements may be imminent. In a message titled “COVID-19 Update,” state officials say immunization requirements “remain in place for now. Any updates will be posted here.”But history and medical science suggest it will take time before states make a COVID vaccine mandatory for children, according to Dr. Rahul Gupta, the chief medical and health officer at March of Dimes.SEE ALSO: States have authority to fine or jail people who refuse coronavirus vaccine, attorney saysMarch of Dimes is the non-profit organization that funded the search for a polio vaccine in the 1950s.“We’re seeing a repeat of history in so many ways,” Dr. Gupta said.Fear of the deadly polio virus prompted quarantines, social distancing and a run on breathing machines. In those days, doctors used iron lungs.With funding from March of Dimes, Dr. Jonas Salk launched a massive clinical trial on 1.8 million kids using his experimental vaccine in 1954. Almost exactly a year later, in April 1955, he announced the vaccine was safe and effective.Within days, five million kids got the first dose of Salk’s vaccine. But the State of California did not mandate the polio vaccine for children entering schools for six more years -- in 1961.The most recent vaccine added to California’s required immunization list was for chickenpox in 2000. That was five years after that vaccine became available in the U.S.When a COVID-19 vaccine is ready in the U.S., children will not be among the first inoculated, Dr. Gupta said. Unlike polio, the novel coronavirus tends to spare children from the most severe symptoms.“The supply will require us to make sure that we prioritize the highest risk population, including healthcare workers,” he said.It’s also unclear how children would respond to the COVID-19 vaccine. Current vaccine candidates against the coronavirus are being tested on adults not children, according to CDPH, and children mount different immune responses than adults.Experimental vaccines can also have difficulties in the production process. In the infamous Cutter Incident, one of the six labs licensed to produce the polio vaccine accidentally let live virus slip into the shots, leading to more than 250 cases of polio, including instances of paralysis and deaths.The incident prompted sweeping safety changes in the U.S.Dr. Gupta said the Cutter Incident shows vaccines need to be rolled out carefully.“We have to understand that that’s a process and we learn as we go along,” he said. “There could be some adverse events that happen from any drug, much less a vaccine that you take. Foods give you allergies. It’s not an unknown side effect.”State officials could a new vaccine to California’s mandatory list by passing a bill or through a regulation issued by CDPH.The process can often take years, but CDPH said in an emergency the process could be “greatly accelerated.” 3189

SAN DIEGO (KGTV) - Authorities are investigating a threat to the San Diego County Administration Center by a former county employee.The specifics of the threat and how it was made was not immediately clear but the threat was being taken "very seriously," Chief Administrative Officer Helen Robbins-Meyer said in a letter to county employees.The employee, who was not named, no longer works with the county.RELATED: San Diego Unified School District, San Diego police outline school safety effortsSan Diego Sheriff's Department was notified, made contact with the person, "and took appropriate action to minimize the threat."

SAN DIEGO (KGTV) — Caltrans is starting a yearlong pilot program in San Diego to reduce wrong-way driving.The agency has installed markings at 30 locations that include red arrows and "DO NOT ENTER" written across the pavement that are only legible when driving in the wrong direction onto freeway ramps.The markings will stay up until the end of the year, according to Caltrans.The agency says that a previous three-year pilot program helped reduce wrong-way driving by 44% in San Diego. The program utilized special reflectors, sensors, and illuminated signs in early 2018.Now, those specialized reflectors have been installed on hundreds of miles of highways, according to Caltrans."The number of wrong-way drivers decreased significantly during the initial pilot program," said Caltrans Director Toks Omishakin. "The addition of these markings, along with what we have learned thus far, will go a long way as we continue to study ways to deter wrong-way drivers."While wrong-way crashes only account for less than 1% of all crashes on California's highways, they are often among the deadliest, Caltrans said."We are constantly looking for ways to improve safety on the transportation system," said Caltrans (San Diego area) District 11 Director Gustavo Dallarda. "If the testing of this new product is successful, it could provide a new tool to reduce wrong-way driving." 1383

  

SAN DIEGO (KGTV) -- Average rainfall and warmer temperatures, that’s what the San Diego office of the National Weather Service is forecasting this winter.With a few windows of opportunity for significant precipitation from December to March, it will be a warm and dry winter with more Santa Ana winds expected, according to City News Service.The National Weather Service predicts that San Diego’s best chance for rain in the near future will be in mid-November.The maps below show what the rest of November is expected to bring as far as rain and temperatures: RELATED: Check today's forecastRecently, winters in Southern California have trended toward fewer rainy days with heavier precipitation.“If we don’t get that rain in mid-November, then we’re talking about severe fire weather conditions again like last year going into December,” National Weather Service meteorologist Alex Tardy said.10News meteorologist Megan Perry said El Nino conditions are starting to develop. “El Nino is favored (70 to 75% chance) to form and continue through the winter. While historically El Nino favors wetter than normal conditions to the Desert Southwest, that doesn't always happen.”More recently, La Nina, or cool equatorial ocean temperatures, has coincided with wet winters in San Diego.The most recent El Nino event in 2015-2016 didn’t bring much rainfall to the region while the La Nino of 2016-2017 brought heavy rain and snow to California, carrying the state out of drought.“At this point, it's a wait and see and hopefully we'll get more rain - we need it after last winter finished as the second driest on record,” Perry said. 1650
