What viruses do we have vaccines for?
Vaccination protects against these 14 diseases, which used to be prevalent in the United States.#1.
Polio is a crippling and potentially deadly infectious disease that is caused by poliovirus.
The Flu (Influenza) …
How was polio stopped?
Strategy. The most important step in eradication of polio is interruption of endemic transmission of poliovirus. Stopping polio transmission has been pursued through a combination of routine immunization, supplementary immunization campaigns and surveillance of possible outbreaks.
What are the most successful vaccines?
Smallpox vaccination with vaccinia virus is the most famous example of a highly effective vaccine and at the time when people were faced with smallpox outbreaks, this vaccine was associated with each of these characteristics that led to the implementation of a successful vaccine.
Can viruses be destroyed?
Inside cells, there are enzymes that destroy the RNA of viruses. This is called RNA interference. Some blood cells engulf and destroy other virus-infected cells.
Are viruses alive?
So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Where are vaccines manufactured?
“China is currently producing nearly all of the commonly-used vaccines for viral diseases such as influenza, measles, rabies (for humans), mumps, rotavirus, hepatitis A and B and for bacterial diseases, including typhoid, tetanus and diphtheria,” says Dr Xu Ming, Vice President of the China Chamber of Commerce for …
What is the oldest vaccine?
The smallpox vaccine was the first vaccine to be developed against a contagious disease. In 1796, the British doctor Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus.
How are vaccines developed for viruses?
Vaccines are made by taking viruses or bacteria and weakening them so that they can’t reproduce (or replicate) themselves very well or so that they can’t replicate at all. Children given vaccines are exposed to enough of the virus or bacteria to develop immunity, but not enough to make them sick.

What viruses have we eradicated?
Two infectious diseases have successfully been eradicated: smallpox and rinderpest. There are also four ongoing programs, targeting poliomyelitis, yaws, dracunculiasis, and malaria.
Why do some vaccines last longer than others?
Some designers hold fast to the idea that a live but weakened pathogen—or genes from it stitched into a harmless virus that acts as a Trojan horse—induces the longest-lasting, most robust responses. Just such a weakened virus is the basis of the measles vaccine, for example, which protects for life.
Which disease does not have a vaccine?
There are no vaccines with long-lasting protection against malaria or tuberculosis. None for parasites like Chagas, elephantiasis, hookworm or liver flukes. None for some viral threats that could become pandemic, like Nipah, Lassa and Middle East Respiratory Syndrome.

What diseases were eradicated by vaccines?
So far, we’ve used vaccines to entirely wipe out two diseases: smallpox and rinderpest, which infects cattle. We’ve also come extremely close to eradicating polio, with less than 500 new cases annually, largely in Afghanistan, Nigeria, and Pakistan.
