In the case of the flu shot, this means killing the flu virus before it gets a chance to make you sick. This means that the next time the immune system runs into that particular pathogen, it’ll be ready to strike. By injecting it, the immune system gets a chance to learn about it and produce the necessary antibodies. In the meantime, the person in question is probably pretty sick! Vaccines work by containing a deactivated version of the pathogen in question. The immune system has to “learn” about each new pathogen and that takes time. The problem is that if it’s a new pathogen-like, say, the flu when you haven’t had a flu shot-it takes time for the body to recognize and defend against it. Once an antibody recognizes a pathogen, the entire immune system leaps into attack mode and the pathogen is destroyed. The immune system produces antibodies-proteins that react to a specific pathogen. When a disease-inducing organism, known as a pathogen, enters our system, our immune system can fight it off. For example, can the flu shot really give you the flu? We’ll delve into vaccine science, focusing a bit on flu shots. It’s worth looking at how vaccines work and whether or not there’s any potential harm. This type of thinking is very dangerous and the reason why diseases like polio and measles are making a comeback. Vaccines make a lot of people nervous to the point where there are entire communities rejecting them and even refusing to give their children basic vaccinations. Don’t try to kill it-again, most are harmless, and messing with the spider puts you at greater risk of being bitten. If you see a black widow, respect its space and leave it alone. While we’re at it, black widows do not chase people or go out of their way to bite-it’s always done in self-defense. Even then, it’s extremely rare that they cause major complications (so it’s even rarer that a bite is lethal), especially if medical care is involved. They are venomous but only the bites of the female are dangerous. The “widow” spiders are a genus, not a species, and so “black widow” can mean a different species of spider depending on where you live.
OK, so spiders are arachnids, but they fit well in this list.

Some versions of the myth even suggest that they crawl up there to lay eggs! In reality, earwigs do not seek out human ears. There’s a myth that earwigs crawl up ears…hence the name. Here, we’re going to delve into a handful of the most common ones. To make matters worse, they often act differently in captivity than in the wild, resulting in even more myths. They’re small and hard to observe so it’s no wonder we’ve come up with tons of crazy ideas. Insects have been the source of myths and wives’ tales for as long as humans have had to deal with them.
