Johnson\u2019s Janssen is a viral vector vaccine, which delivers DNA &#8220;instructions&#8221; to the body\u2019s cells via a different, non-harmful virus.<\/p>\n<p>The Novavax vaccine is a protein subunit vaccine, which uses some proteins of the virus that causes COVID-19 \u2014 known as the &#8220;spike protein&#8221; \u2014 to &#8220;train&#8221; the immune system to act against future spike proteins.<\/p>\n<p>The nasal COVID vaccine that&#8217;s being tested is a live-attenuated vaccine, which means it contains a live but weaker form of the coronavirus.\u00a0<\/p>\n<p>It works by stopping the virus in the upper airway before it can travel further into the body.<\/p>\n<p>The researchers used Syrian hamsters for their vaccine testing.\u00a0<\/p>\n<p>The study\u2019s lead author, Dr. Jakob Trimpert, head of diagnostics at the Institute of Virology at Freie Universit\u00e4t Berlin <a href=\"https:\/\/www.foxnews.com\/category\/world\/world-regions\/germany\"><u>in Germany<\/u><\/a>, said hamsters are the &#8220;prime non-transgenic [not genetically modified] small animal model&#8221;

he explained to Fox News Digital.\u00a0<\/p>\n<p>&#8220;The infection of Syrian hamsters resembles many key features of moderate human COVID-19 \u2014 this makes the hamster an ideal model to <a href=\"https:\/\/www.foxnews.com\/category\/health\/medical-research\"><u>study COVID-19 vaccines and therapies<\/u><\/a>.&#8221;<\/p>\n<p>The nasal vaccines have significant advantages over the injectable vaccines that are currently available, Dr. Trimpert said.\u00a0<\/p>\n<p>&#8220;An intra-nasally applied live-attenuated vaccine provides superior protection against <a href=\"https:\/\/www.foxnews.com\/category\/health\/infectious-disease\" target=\"_blank\" rel=\"noopener\">SARS-CoV-2 infection<\/a> compared to intramuscularly applied vaccines,&#8221; he told Fox News Digital.<\/p>\n<p>While he said currently marketed vaccines do a good job of preventing severe illness from COVID, Dr. Trimpert pointed out that they don&#8217;t prevent the infection, moderate illness or spread.<\/p>\n<p>&#8220;We find that a live attenuated vaccine prevents virus replication&#8221; \u2014 so &#8220;this could be a game changer in controlling SARS-CoV-2 transmission.&#8221;<\/p>\n<p>The main benefit of a nasal vaccine is that immunity is activated right where it\u2019s needed, Dr. Trimpert said.<\/p>\n<p>&#8220;It is the induction of local immunity at the site of natural infection that could be a game-changer here,&#8221; he said.\u00a0<\/p>\n<p>&#8220;Judging from our results, this has considerable impact and greatly reduces the risk of infection.&#8221;<\/p>\n<p>Dr. Marc Siegel, professor of medicine at <a href=\"https:\/\/www.foxnews.com\/category\/us\/us-regions\/northeast\/new-york\"><u>NYU Langone Medical Center<\/u><\/a> and a Fox News medical contributor, said he finds this new research promising.
