SAN DIEGO (KGTV) — Infectious disease experts say it may take months before the first doses of a COVID-19 vaccine reach an important population: kids.Some doctors worry it may already be too late to get a vaccine authorized for younger kids before the start of the next school year because of the time it takes to recruit children and conduct a new round of clinical trials.“Our children under 12 years of age are almost certainly going into next school year without a vaccine option available for them,” said Dr. Evan Anderson, a pediatrician at Children’s Healthcare of Atlanta and associate professor at Emory University.Dr. Anderson said such a delay could further impact school reopenings and have resulting consequences on children’s mental health, among other concerns. He said the window is rapidly closing to get a vaccine authorized in time for children older than 12 unless more trials begin immediately.In October, Pfizer tested its vaccine candidate for the first time in 100 kids aged 12 to 15. Moderna is expected to begin testing in that age group in January, according to Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases. However, neither company has announced plans to begin testing their candidates in children under 12.That’s concerning to the American Academy of Pediatrics, which has been calling on vaccine-makers to include children in clinical trials since September. The AAP argues immunization is critical to stemming the pandemic.“We know that children can be infected with COVID-19 and can transmit it to others. To reduce the spread of this virus and control the pandemic as well as for their own safety, it’s crucial that children be included in the national vaccination program, and that vaccines are made available to children as soon as possible,” said Dr. Yvonne Maldonado, chair of the AAP Committee on Infectious Diseases, in another push last month.Although COVID-19 takes a more severe toll on older adults, children make up about 12 percent of the infections in the U.S. and recent studies have shown kids over 10 years old can transmit disease as efficiently as adults, the AAP noted.More than 1.3 million kids had been infected with COVID-19 as of Nov. 26.Experts say it’s important that drug companies test COVID-19 vaccines in children separately from adults.“Kids' immune systems are really different than adults. As any pediatrician will tell you, kids are not just small adults, their immune systems behave really differently,” said Dr. Christian Ramers of Family Health Centers of San Diego.Dr. Ramers said testing is needed to find the right vaccine dose for kids and see if there are any unexpected side effects.But there are challenging logistics in any pediatric trial. Since children’s immune systems change as they grow, vaccine-makers have to separate their trials into several age groups. That means more child volunteers are needed.“I mean it's more challenging, as an investigator myself for research, to enroll a kid into a study because you have to get permission [from parents],” said UC San Francisco infectious disease expert Dr. Peter Chin-Hong.Because parents have to sign off, experts say it can take much longer to enroll enough kids for a study.In a statement to ABC 10News, Pfizer said it is “working actively with regulators on a potential pediatric study plan.”“As we do with all vaccines which are initially studied in adult populations, we are following a careful, stepwise approach as we move down to younger age groups,” said Jerica Pitts, Pfizer’s director of global media relations.“Global regulatory agencies require evaluation of the candidate vaccine in pediatric populations. Moving below 12 years of age will require a new study and potentially a modified formulation or dosing schedule,” she added.Could a vaccine become mandatory at schools?Once a vaccine is approved for kids, a lot of parents are wondering if and when it might become mandatory at California schools.The California Department of Public Health told ABC 10News several things would need to be in place before it would consider making a vaccine mandatory at either schools or child care facilities.The vaccine would need to reviewed and approved by the FDA and recommended for use in children by the federal Advisory Committee on Immunization Practices. The state would also look for a recommendation by the American Academy of Pediatrics, and there would need to be "sufficient vaccine supply to enable access for all children."READ MORE: Will California make the COVID vaccine mandatory at schools? 4602

SAN DIEGO (KGTV) — In 2004, San Diego taxpayers approved a transportation tax increase that earmarked 0 million for bike projects for more bike lanes, safety features on the roads for cyclists and foot traffic, and new walking trails.Friday, SANDAG said it's going to need more. Officials said rising construction costs have called for an additional million for the projects, many of which have been started.The money would come from funds already allocated for these types of projects.RELATED: Compromise proposed for 30th Street bike lanes in North ParkCritics of the increase in funding argue only one percent of San Diegans use bikes and costs of .5 million per mile built for these bike lanes is unjustified.The San Diego Bike Coalition says the funding is needed to provide San Diegans with more transportation options, reduce auto dependency, and increase safety of bicyclists. They add that an expanded bike network will help the county move closer toward greenhouse emissions goals.SANDAG has been working toward the biking goals since 2013, when the agency approved a 0 million Bike Early Action Plan. The plan, funded by the region's half-cent tax on public transit fares, includes 40 projects totaling 77 new miles of bikeways and paths around the county.Crews broke ground on the first phase of the project last December and expects to complete two projects by early 2022. 1405

SAN DIEGO (KGTV) -- Mayor Kevin Faulconer is among local leaders expected to leave for Mexico City Sunday morning. The trip, which includes Imperial Beach Mayor Serge Dedina, is meant to strengthen ties between the border. The mayors plan to discuss border infrastructure projects, pollution in the Tijuana River Valley and economic ties with leadership in Mexico. RELATED: Trump threatens to 'close' parts of US/Mexican border if Mexico doesn't immediately halt immigrationThe trip comes as President Trump said he would shut down the border with Mexico if the country doesn’t handle the wave of asylum seekers entering the U.S. The San Diego Regional Chamber of Commerce says shutting down the border would have severe consequences. “Our daily lives are effected by the border crossings and how long that takes. So we certainly wish that not to be something to be toyed with,” said Jason Wells, Executive Director of the San Ysidro Chamber of Commerce. The San Ysidro Port of Entry is the busiest land crossing in the U.S. with nearly 100,000 vehicles and pedestrians crossing every day. 1098

SAN DIEGO (KGTV) - If San Diego County has a case rate higher than 7.0 next week, it could be moved into the state’s purple tier which is the most restrictive tier for area businesses.Wednesday, county health officials said San Diego County was at a 4.5% testing positivity rate and 7.9 cases per 100,000 people. The current case rate it over the state's threshold of 7.0 cases per 100,000 residents reserved for the purple tier, the state's most restrictive.According to a breakdown from the California Department of Public Health, retail stores will have to lower to 25% capacity indoors, from 50% capacity.Restaurants must move to outdoor dining only, after operating at 25% capacity indoors or 100 people, whichever is fewer.Shopping centers will move to 25% capacity with closed common areas and a closed food court. They're currently operating at 50% capacity with closed common areas and a limited food court.Personal care businesses must move to outdoor operations after working indoors with modifications.Museums, zoos and aquariums will go to outdoors only after operating at 25% capacity indoors.RELATED: San Diego County wants SDSU's coronavirus cases nixed from case ratePlaces of worship and movie theaters will be held outdoors only, after operating at 25% capacity or 100 people.Gyms and fitness centers will also have to go outdoors only, after being open at 10% capacity indoors.Professional sports will remain the same and continue to operate but without live fans in stadiums.While the county's testing positivity has sat in the third tier (orange) for two weeks now, a county must meet both metrics for two weeks to move forward with less business restrictions."At a minimum, counties must remain in a tier for at least 3 weeks before moving forward ... To move forward, a county must meet the next tier’s criteria for two consecutive weeks. If a county’s metrics worsen for two consecutive weeks, it will be assigned a more restrictive tier," the state's website says. 1998
