SAN DIEGO (KGTV) — The CDC is making plans to distribute millions of doses of a coronavirus vaccine by late next month, but government officials have gotten these predictions wrong in the past.Doctors and scientists say there are reasons to be skeptical of the timelines laid out by Operation Warp Speed based on the lessons of 2009 and 1976.During the height of the H1N1 Pandemic in 2009, San Diegans waited in long lines to get vaccinated only to find there were not many doses to go around.The CDC initially projected there would be 120 million doses of vaccine ready by October 2009. Then federal officials scaled back the projection to 45 million.By the end of October, only 23 million doses would become available due to delays in the manufacturing process.“The lesson of H1N1 is that you may make all the plans on paper, but the actual nuts and bolts of rolling it out is really challenging and not to be underestimated,” said Dr. Peter Chin-Hong, an infectious disease specialist at UC San Francisco.Manufacturers had trouble growing the H1N1 vaccine in chicken eggs, the most common method for producing flu vaccines. There were also issues with testing the vaccine’s potency and problems switching production lines from the seasonal flu vaccine to the H1N1 strain, according to an after-action report by the Department of Health and Human Services.A lot goes into making a vaccine, said Dr. Rahul Gupta of March of Dimes.“It's not just the vaccine but also the syringes, and the needles, and the stoppers, and the alcohol pads,” he said. “There are so many other things that go along when we talk about a vaccine.”By the time the vaccine was widely available, the pandemic had petered out.Experts say there are also some parallels to what happened in 1976.During the height of an election cycle, President Gerald Ford fast-tracked a vaccine after some soldiers on a military base in New Jersey got sick with a strain of H1N1, then called Swine Flu, that was genetically similar to the strain that killed millions in 1918.“Some scientists were telling Gerald Ford that this was going to be as bad as Spanish Flu,” said Dr. Chin-Hong.The U.S. launched a huge media campaign, urging Americans to get vaccinated.President Ford rolled up his sleeve and got the vaccine, along with one-quarter with the U.S. population, beginning in October of 1976.However, the viral strain they were worried about never spread beyond the military base, and there were rare side effects linked to the vaccine. Of the 45 million people inoculated, about 450 people developed Guillain–Barré syndrome and about 30 people died.One month after the vaccinations began, Ford lost the election and the episode became known as the “Swine Flu Affair.”Experts say it’s normal to have adverse reactions and production delays on the road to a vaccine.“We have to understand that’s a process. And we learn as we go along. And people have to trust the process as well,” Dr. Gupta said.But doctors say it’s a process that takes a lot of coordination, and there are aspects you just don’t want to rush. 3081

SAN DIEGO (KGTV) -- The latest water main break Sunday in the Midway District is the latest example of San Diego’s aging water system. But the city is working to fix the issue, replacing more than 100 miles of water transmission and distribution pipes.According to city documents, since 2013, San Diego spent 8 million to repair and replace 116 miles of water transmission and distribution pipes.A total of 72 miles of those repairs were on cast iron pipes, the oldest ones in the system. The project started in 2007 and sparked a rate increase to pay for the work.RELATED: Water main break in Midway District causes flooding, shuts down roadAs older piper are replaced, the city has seen the number of water main breaks decrease. "We have more than 3,000 miles of pipeline," said department spokesperson Brent Eidson, "To do it properly, we're probably always going to be replacing pipes."Throughout the project, older pipes made from concrete or cast iron are being replaced with new PVC pipes. Edison says PVC is the industry standard. Pipes made from the material usually last between 50-75 years.The city says its water system extends more than 400 square miles and moves roughly 172 million gallons per day. Included in that area is 49 water pumping stations, 29 treated water storage facilities, three water treatment plants and more than 3,300 miles of pipelines.The city hopes to have all the cast iron distribution lines replaced by 2018-19. The goal is to have all the larger cast iron transmission mains replaced by 2023. Some of the cast iron pipes are nearly 100 years old.The following numbers were provided to 10News by the Public Utilities Department and list the number of breaks over the last six years.2012: 1022013: 952014: 742015: 632016: 852017: 81 (as of October 20)2018: 29 (as of August 5) 1841

SAN DIEGO (KGTV) - The California Senate will vote this week on a bill to add a surcharge to utility bills, with the money going to pay for damages caused by wildfires.Governor Gavin Newsom says he wants the bill on his desk to sign by Friday before the legislature takes its summer break.According to the text of Assembly Bill 1054, each utility company would have to "collect a nonbypassable charge from its ratepayers to support the Wildfire Fund." That money would go to pay for damages from wildfires caused by utility companies.But the fund can only be used if the utility companies comply with state safety laws and regulations.The bill also requires each electric company to file a wildfire mitigation plan with the state every three years, and update it yearly.Critics say it's nothing more than a tax, passing the responsibility of wildfire damage away from the utility companies and onto rate-payers."This is going to be a tax that will go on, who knows how long," says Richard Rider from the San Diego Tax Fighters. "Long after the utilities have buried their wires, long after the risk has dropped dramatically, the ratepayers will still be paying it."Rider says this bill would unfairly make people in low-risk areas pay into a fund that would only benefit people in high-risk areas.RELATED: PG&E equipment may have caused Camp FireAn SDG&E spokesperson says the company does not have an official position on AB 1054 but sent a statement to 10News saying:"We believe this bill is a good starting point for legislation to be enacted by July 12 to help address some of the legal, regulatory and policy challenges facing California, as the state grapples with the wide-ranging impact of catastrophic wildfires. We look forward to reaching a final agreement with the Governor and Legislature that meaningfully addresses the crisis posed by wildfires. Their sense of urgency in dealing with the situation is commendable."The bill will be in the Senate Appropriations Committee on Monday. It has already passed through the Assembly. 2052
