I recently posted on ways the number of ticks can be reduced in a backyard. Now an article on vaccines being developed to battle tick borne diseases, especially Lyme disease. However, the bad news is that ticks now transmit 16 diseases in the US (including anaplasmosis, babesiosis, ehrlichiosis), while vaccines typically only focus on one disease at a time. Tick borne diseases are on the rise throughout the world.
We all know about Lyme disease (which is also a problem in Europe, China, and Mongolia), but in parts of Africa, the Middle East, Asia and southern Europe, ticks can spread Crimean–Congo haemorrhagic fever, which is fatal 40% of the time! And while some researchers are focusing on human vaccines, some are focusing on vaccines for mice. Big problem: would we really be able to give the vaccine to enough mice to make a difference? I really like the idea of a vaccine that hampers the ability of ticks to feed on humans. From Nature:
Williams is testing whether vaccinating mice against Borrelia burgdorferi, the bacterium that causes Lyme disease in the United States, can reduce the proportion of ticks that are infected. ....Borrelia burgdorferi infects an estimated 329,000 people in the United States each year, according to the US Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia. And although most people who get prompt treatment recover quickly — Williams has had Lyme three times — up to one in five develops long-term and potentially life-threatening symptoms, including heart, vision or memory problems, or debilitating joint pain. ...continue reading "Vaccines to Battle Tick Diseases?"
