Scientists, doctors and the public are eagerly waiting to hear how effective a COVID-19 vaccine will be and how soon it could be available to everyone. But when the vaccine is ready, some will be racing to be first in line, while others will be cautiously waiting to see how it plays out."Only about half of people get a flu vaccination polls are showing. In terms of the coronavirus, that’s saying that a third to maybe as much as half of the population will not want to get a vaccine," said Arthur Evans, the CEO of the American Psychological Association.Evans is concerned about whether people will be willing to get the COVID-19 vaccine when it comes out. How people are educated about the upcoming vaccine will be crucial."Right now, I think there are a lot of people who want to take a vaccine and to get a vaccine, but if people feel that this has been rushed, that they don’t feel all of the normal safety measures have been taken, it's going to be much harder for people to take that step," explained Evans.Dr. Bali Pulendran, a pathology, microbiology and immunology professor at Stanford University, says just because a COVID-19 vaccine is being expedited doesn't mean it's any less safe."It's a very established, lengthy process. It’s expedited now because of certain technologies such as the mRNA technology that really helps you accelerate this process," said Dr. Pulendran.He says the creation of a vaccine is rigorously tested, first with mice, then primates, and finally, humans. Tens of thousands of people are currently choosing to participate in COVID-19 vaccine trials."And so, this is a development and paradigm that has served vaccinology really well. It's really served it well in terms of enabling the licensure of some 20 or more vaccines," said Dr. Pulendran.Dr. Pulendran says every year, the flu vaccine varies in efficacy. For a good year, it could be 90 percent protective, while the next year, the flu shot may only be 10 percent effective. The COVID-19 vaccine is expected to be 60 percent effective."I think for me, personally, if I saw a vaccine coming out in the next year or so that had a 60 to 70 percent efficacy, that to me would be very encouraging," said Dr. Pulendran.The public, though, may still need some convincing."One of the hardest things for the general public to embrace is the idea of probability. We like to know definitively if something works or not,” said Evans. “The reality is that a vaccine is a probabilistic issue. It's highly likely that you won’t contract, whatever the condition is, but it’s not 100 percent."Evans says the key will be in how the vaccine is marketed to the American public.Dr. Pulendran hopes any positive data and outcomes of the COVID-19 vaccine trial will encourage as many people as possible to get the vaccine when it comes out. 2823

SAN YSIDRO, Calif. (KGTV) - The first eight migrants in a caravan of hundreds will be processed, a source confirmed Monday night. Women and children were the first to be selected out of the group. Earlier Monday, 20 families were waiting to be processed at the San Ysidro port of entry. Customs officers say the border crossing facility is at capacity. Those crossing the border say the caravan is fenced off in two sections. One group of about 20 is at the door, waiting to be processed.Irineo Mujica of Pueblos Sin Fronteras, the group organizing the caravan, called the refusal to process the asylum seekers a 'farce'.MAP: Where is the migrant caravan from?Some 50 Central American immigrants camped on a sidewalk near the San Ysidro Port of Entry Sunday night. They're part of a group of hundreds who intend to enter the U.S.The caravan faces a challenge when, and if, they reach this country. They must have proof of their need for asylum in the United States.Customs and Border Protection says it will resume processing when it has more space and resources. 1101

Security lines and close human interaction at airports could one day be a thing of the past.With the travel industry determined to get people flying again, experts say the motivation to innovate is in overdrive.Airports have a way of fueling anxiety; one misstep can send even the most seasoned travelers into new heights of annoyance.So, could it ever be an experience we actually look forward to? The airport industry certainly hopes so.Justin Erbaci, the CEO of Los Angeles World Airports, says the innovations that land in your airport are usually tested at LAX first.“We’re using this as a platform to push forward a lot of things we wanted to push through, but there wasn’t the interest or the buy-in from government agencies or the industry, or the willingness to invest in these types of solutions,” Erbaci explained.Now, the industry is hearing customer complaints loud and clear, looking to revolutionize the airport experience.“That’s the goal for us, is to allow people to come through the airport and not have to see anyone and be able to serve themselves throughout the whole process,” he said.The first leg of your next airport experience could include the following:A touchless kiosk you can operate with your smartphone to check-in to your flightChecking luggage? This self-service system takes your bags without the need for an agent“A lot of things that are standard today seemed crazy when we first heard about them,” Erbaci said.As far as security goes, long lines leading to a TSA agent could also go away. Instead, passengers could be screened with biometric facial recognition technology.It’s already a reality at Dubai International’s smart tunnel, which the government says gets travelers through passport control in 15 seconds.LAX has tested this technology with passengers boarding flights, so they don't have to pull out their boarding pass."Through surveys, we’ve done over the years…seen people are willing to consent to give up identity aspects to get through the process faster,” Erbaci said.And carry-on bags could be screened using remotely-operated X-ray machines.While a completely self-service experience is likely several years away, changes are being implemented now to improve TSA screenings.“We have new technology that has been rolled out at dozens of airports across the country that allows the traveler to insert their ID or scan their own passport,” said TSA spokesperson Lorie Dankers.Dankers says the agency is looking at innovations being used around the world.“They test to make sure they don’t compromise security in the airport environment,” she explained. “We look to those cutting-edge technologies to make sure we are on the forefront of that.“We can’t think we’re going to be able to recover from an unprecedented situation by using old methods and means. We have to change.” 2839

SAN YSIDRO, Calif. (KGTV and AP) -- As the migrant caravan approaches the U.S.-Mexico border, several lanes in San Ysidro and Otay Mesa will close so new equipment can be installed.According to U.S. Customs and Border Protection, at least three northbound lanes in San Ysidro and one in Otay Mesa will close until after the caravan arrives.The closures are an effort by the Department of Defense to install concertina wire, and pre-positioning jersey barriers, barricades, and fencing as requested by CBP under Operation Secure Line. 551
