I just received a vaccine for yellow fever with a live virus today. If yellow fever can be spread by a mosquito and the means of transmission is basically needle like. What makes the vaccine any different from a mosquito bite?

They are made from weakened forms of the disease. It is possible to actually get the disease from a live vaccine, but it is a rare happening. Polio is a good example because it is quite rare in the US (in other words, no wild virus left). That used to be a live vaccine, but college students were getting the illness from the vaccine (about 15 a year), so now in the US only the injectable killed vaccine is used.
I'll be you will ask why everybody doesn't use the killed polio vaccine. In 3rd world countries, there aren't enough trained people to give injectables. The suspension (drink) makes it possible to get everybody covered even though a portion of the population will then get polio.

The virus in live virus vaccines has been "attenuated" so that it will induce an immune response, but it will not cause the disease. Basically, the viruses in the vaccine have been mutated in a way that they are harmless to you, but "trick" your immune system into thinking you've been exposed to the real virus.

the reality that we live and respiratory and waiting to accomplish a little of those issues. the reality that we are no longer rocks and a few divine accident made use who we are instead of a few inorganic atom. the reality we could provide issues nicely worth. we are able to categorise. Its all captivating, the sight, the sound, the feel, the emotion, the flavor. Even soreness. we are able to experience that no longer many different issues can. soreness may be painful, yet we are able to experience it purely as we are able to experience happy. Its magnificent particularly that out of all of this we are able to do those issues. besides the reality that it variety of feels to suck from time to time its nevertheless astonishing. random actuality: in case you shoot a rabbit, it doesnt understand why it feels soreness, it does not sign in that there is an evidence, it purely is acquainted with it feels soreness and as a reaction will run away, in spite of if its dying. Shoot a human (in spite of in the event that they did no longer understand what a gun became into) it may understand its some thing released, have some type or awareness of what to do etc. I dont think of this became into correct yet its written now... yet whilst youre searching for one reason it may particularly be pie.

The virus in your vaccine is somehow tampered so that it would not make you sick but still activate the defense mechanism of your body. They could bombarded this viruses with UV rays, destroying their DNA but keep the protein coat intact. The protein coat could still activate our immune system, but, lacking DNA, it would not be able to reproduce itself, hence, cause no disease.

a vaccine is a weakened virus. once the weakened virus is in your system, your body's immune system will make special antibodies to kill the virus, thus giving you an immunity to that virus
the actual virus is not a weakened one, but the real virus. Once you get it, it is hard to get rid of.

It's not just about amount, but about potency too. It's a weaker form of the virus. A portion that your body can handle and develop a defense against.

yellow fever vaccine is an attenuated modified live (not virulent) The difference is the vaccine will protect you for life and the virulent form can kill you

The difference is that the one you got is only a weak one.You only got a virus to train your defense from that virus.The one from the mosquito is the perfectly good virus that is not training your defense ,it's destroying it.
