SAN DIEGO (KGTV) - The Department of Homeland Security is responding to the caravan of Central American immigrants prepared to enter the United States through the border with Mexico.At least 600 people from Guatemala, Honduras, El Salvador, and Nicaragua are traveling to Tijuana, according to freelance journalist Jorge Nieto. About 100 arrived last night. Eventually the group will enter the U.S. at the San Ysidro port of entry.Homeland Security Secretary Kirstjen Nielsen released a statement on the caravan.“DHS continues to monitor the remnants of the ‘caravan’ of individuals headed to our Southern border with the apparent intention of entering the United States illegally. A sovereign nation that cannot – or worse, chooses not – to defend its borders will soon cease to be a sovereign nation. The Trump Administration is committed to enforcing our immigration laws – whether persons are part of this ‘caravan’ or not.”RELATED: Migrant caravan heads toward US-Mexico borderDHS warned members of the caravan that they may be turned over for prosecution under illegal entry laws. Anyone seeking asylum may be detained while their claims are processed, DHS said.“Again, if you enter the United States illegally, let me be clear: you have broken the law. And we will enforce the law through prosecution of illegal border crossers,” Nielsen stated.The DHS statement encouraged those with asylum claims to seek protection in the first safe country they enter, naming Mexico as a possibility.SLIDESHOW: Migrant caravan travels through Mexico“While we are committed to doing everything we can on the border to secure our nation, we need Congress to do their job as well.  I join the President in asking Congressional leadership to work with the Administration to pass legislation to close the legal loopholes that prevent us from securing our borders and protecting Americans. I stand ready to work with any member who in good faith seeks to support DHS’s mission and secure our country,” Nielsen wrote.RELATED: Hundreds of migrants reach Tijuana 2060

SAN DIEGO (KGTV) — The back-to-back announcements of promising clinical trial results from Pfizer and Moderna may usher in a new era for vaccine technology.Both companies have candidates that rely on a new kind of vaccine strategy: RNA. Preliminary data show both candidates are more than 90 percent effective.On the surface, the vaccine candidates look like any other you’ve taken. They work by training your body to build up defensive weapons against a virus, like antibodies and T-cells.But instead of training your body by introducing a killed virus or a fragment of a virus, the vaccines from Moderna and Pfizer introduce a set of instructions called messenger RNA enclosed in a little blob of fat.“The key concept of RNA is that they’re messages, and they’re meant as short-term messages,” said Dr. Shane Crotty of the La Jolla Institute for Immunology.Crotty said there are 5,000 to 10,000 messages within a cell at any given time.Once administered, the mRNA in the vaccine instructs some of your cells to make the coronavirus’ signature spike protein. The spike protein on the surface of the coronavirus allows it to infiltrate and hijack cells.Even though the spike protein is just one of about 25 genes the virus has, preliminary results from the clinical trials suggest it is enough material to train the immune system without making the recipient sick.Crotty likened the process of training the immune system to spotting a sedan. If the coronavirus is a car, the spike protein might be the door.“There's no way that car door could turn into a whole car, but it's enough of a piece of a car for your immune system to recognize that car if it saw it again,” he said.Scientists started by sequencing the virus’ DNA from a sick patient, then encoding that genetic sequence into an mRNA instruction molecule that can be read by the manufacturing part of cells.From there, Dr. Crotty said it’s a bit like the messenger app Snapchat.The mRNA gets injected into the body, sending temporary instructions to your cells that last for a while, then disappear. mRNA does not genetically modify cells, he stressed.“They’re around as messages for some period of time and then they go away, and the cells get back to their normal job of reading their own messages instead of reading the messages you’re injecting in the vaccine,” he said.The concept has been around since the 1990s, but there are currently no RNA vaccines on the market for any pathogen, so Dr. Crotty said it’s hard to estimate how long their protective effects will last.Some vaccines offer a lifetime of protection, like the measles vaccine. Others offer decades of protection. The flu vaccine only lasts about six months.Dr. Crotty said the length of protection depends on how fast the virus mutates and how long the immune cells survive in the body.But even if the COVID-19 vaccine turns out to need an annual update, he’s optimistic. The best feature of RNA vaccines is that they can be quickly reprogrammed.Both Moderna and Pfizer are still in their Phase 3 trials, but they expect to finish them by December. Together, they estimate they’ll have enough doses for about 35 million people by the end of this year, primarily for healthcare workers and high-risk individuals. 3250
