Some vaccines do protect against viral diseases such as the vaccine against chickenpox. However, vaccines against viruses are very difficult to make. Not only are viruses very small, but they are not living organisms. Viruses require a living host to carry on certain processes. Vaccines tend to kill a bacterium or a specific organelle of a bacterium that would affect its ability to survive and carry on its normal functions. Due to the fact that viruses are not living this poses a problem to the normal approach.
It activates the body's natural defenses and puts the body on "alert"
they do put the body on "alert" plus Vaccines introduce dead or dying viruses into the body, which results in the immune system producing T-bodies to help kill these weakened invaders. The T-bodies remain after the virus is eradicated, and providing there isn't a mutation in the virus, one will likely never suffer from the full-blown disease. Vaccines turn on your secerity on ur body to help prevent a virus from producing and destroying ur cells
both answers are correct but mine explains enough to make u understand
no offensive tings in mind
your answer is just as good as mine.:)
it kills the virus by injecting it with a fluid, therefor killing the virus
Antivirals, Antibiotics
histamine is actually the wrong answer! it is interferons (which are proteins) and they are called that because they "interfere" with the virus.
yes, nucleoside analogues are artificial nucleosides. The block the completion of new viral DNA chains, therefore, preventing the production of new viral bodies. This way the viral enzyme, reverse transcriptase is more likely to incorporate the nucleoside analogue into the DNA than the host's DNA polymerase.
Almost all diseases cannot be caught from kissing someone. You can however get bacterial and viral infections from kissing someone who has those infections.
A person with a Masters of PhD in Viral studies, or an MD who specializes in infectious diseases mainly viral infections, usually also has a MD, PhD. One is pure research the physician does research as well as treatment and prescription.
Flu, bird flu, swine flu, other respiratory viral infections, strep throat, pneumonia and tuberculosis are but few of the diseases, that are caused by droplet infections.
No. Vaccines are not used for treatment. They are used as prevention.

Prevention of infectious diseases when vaccines are available for them. There are vaccines available for many viral and some bacterial contagious diseases.
I depends on the disease. Viral diseases often have vaccines. Heart disease can be prevented with good diet and excercise. Mosquito borne diseases can be prevented by using insect repellent.
Yes. Bacterial diseases can be treated with antibiotics. Viral diseases have to run their course. Many viral diseases have vaccines available, such as flu, measles, mumps, chicken pox and so on. If your cold or flu turns into pneumonia, then that can be treated since it is bacterial.

to wash your handsWash your hands.
You can always wash your hands after going to the bathroom be very clean and not get close to those who are sick
Viral diseases are caused by viruses which live in our cells as a host. So, killing them by antibiotics means killing our own cells. This is why antibiotics are not effective against viral diseases.
antibodies
Vaccines are used to make your body produce antibodiesand T-cells against viruses or bacteria! The Measles and Flu vaccines are viral. The Whooping Cough (Pertussis) and Tuberculosis vaccines are bacterial.
Yes, a large percentage of vaccines are for viral infections, there are not many vaccines for bacterial infections but there are a few. The flu is caused by a virus, vaccinations against the flu work very well, for example.
