If you prevent the news from world scientists, then it should be noted that vacancies work against a realm of dreadful illnesses – or if you are in doubt about that evidence of declarations – then look here.
Vaccines have already removed a bird-related disease, are increasing in the process of others and others are guaranteeing that millions of people are protected from several serious illnesses.
As a WHO, in an email write to videnskab.dk: "Vaccines are one of the greatest successes in modern medicine."
Cups were defeated by the fax
The best example is the vaccine against one tidal disease cups.
Several hundred years ago, sharp peasants and doctors had judged that bowler was less ill with arrow when in contact with cows, with a similar virus, cocoons.
The judgments led Edvard Jenner to perform scientific tears and told it of simple police protection: Make sure you expose a number of illnesses, and you are immune to later attacks. The fax was born.
In 1967, the low point spot was almost rolled into the whole world. In 1980 copper was extinguished.
The cup box is at the same time the biggest success of any world for vacancies so far, but other diseases such as polio and mouths can also be aborted.
Polio is paralysis that does not affect children or young adults. Until all tens of thousands of stars of attacks on the muscles you breathe.
The disease has previously compared hundreds of thousands of people worldwide globally.
Note that the grave is only the trend in the autumn of & # 39; e reported cases of buyer. The numbers are probably much higher: from 50 million cards a year in the early 1950s to 10-15 million in & # 39; In the 1960s, it was used worldwide. Up to 30 percent died of a disease.
Polio called Denmark 60 years ago
In the fifties, polio was washed over Denmark and Norway. Hundreds of Copenhageners were opened simultaneously in one week. Between 1950 and 1954, more than 4,000 polio cases were registered in Norway. The polio spiders were alive by the doctors making a hole in their throat, leaving them in the air & # 39; Maneuvering the lungs.
An article on dr.dk says that 700 doctoral students were required to help the doctors in the Blegdams hospital to look for all the sick to get treatment. An experience that was too hard for the therapists:
"Older colleague's had to help the youngest to get the psychological shock. But it's also physically strict; in necessary situations, it is necessary to stop 16 hours on a bed of a newly addressed patient without interrupting kept, "the article says.
Through the use of a fax in the fifties, the number of patients was significant.
In 2017 there were 22 cases in the world, limited to outbreaks in Pakistan, Afghanistan and Nigeria, according to WHO.
"People are one of the greatest successes on the health field, the polio is increasing," says WHO.
Meal less and less
At the same time, the number of many influences has been established since the 1950s.
If treated, the mouths get relatively miserable consequences, but the disease can lead to otitis, lung and inflammatory flames and, in the least, become fatal. In fact, in one of the poorest countries, until one in 20 children die.
Therefore, it is very important that children get an impression against the disease.
The numbers see how the number of cases falls when more and more one-year-old parents are eliminated:
The effect of vaccines for mouths can also be clearly seen in this graph of the United States, which entered the 1960s vaccinium in 1960:
Vaccines work – when people are eliminated
You hear meal out of knives breaking out of the meantime, especially abroad, even in & # 39; a united states, that does not have a running curve otherwise.
It would not be possible if the factories work.
84 percent decrease in mouth
In 2016, 90,000 people died of mice, most of their children under the age of 5. By comparison, more than 500,000 people died in mears in 2000.
The autumn from 2000 to 2016 is 84 percent. According to the WHO, mrippen vaccines have lived a total of 20.4 million since 2000 2000.
Somehow, however impressive the numbers are, many will not want to enter it or no faxes will arrive. This means that illnesses such as cold can live on some places, even in countries where there is not much intense weight.
A virus can only be lost if it cannot find hosts, for example, if anyone or almost everyone is imported.
Denmark is a good example. Afterwards, the number of infants fell by ± 0 after the MMR invasion in 1987.
In 2017, it was postponed from the northern islands. (The outflow does not mean that there are always 0 cases, but the disease cannot spread because many are intake.)
If you make an impression of what effects faxes have in Denmark, you can see an overview of this overview of Statens Serum Institut:
Do you fax the side effect?
Vaccines can really improve the world.
Vaccines against 26 diseases
26 diseases can now be combated with facials.
24 vacancies are under development, according to WHO's overview.
But as with other good things, there are also disadvantages.
A fax is most of a problem with the one you want to make your body prefer. Even in small amounts, it can cause side effects.
The same can be said about the substances that were added to make the vaccine as effective as so-called adjuvants. If one is influenced by south effects of vaccines and / or adjuvants, it is almost always in the form of lighter suffering such as swelling, fever and headaches.
In very rare cases, the south side effects may increase. The cup vaccine can explain insephalitis. The tranquilization against tuberculosis can cause coals, a polio vaccine can cause a force.
Is worth risking
In the worst case scenario, Szenario – one in a million – each of three so-called live vaccines, such as the Calmette vaccine, can cause death.
According to Morten Ruhwald, psychologist, it is usually associated with the fact that the vaccine has another, very rare disease, for example, an oral fluid.
The security of vacancies is very complete, says Ruhwald, who's in the department of human technology in the Statens Serum-Institut.
– These very rare cases are, of course, terrible for the families, but protect the facials from very serious illness. Children with immunodeficiency have an increased risk of these influences, he says.
Ruhwald is supported by the WHO, bearing in mind that the few disadvantages are small in comparison to all beneficial effects.
When you explain that vacancies explain weakness – such as the HPV vaccine or the MMR vaccine against mouths, mumps, and red dogs – they often fall on anecdotes or detached assumptions and very simply on solid science.
In & # 39; the most prevalent episodes have been refuted many times. You have, of course, heard that a study shows that the MMR fax can survive autism? This study was trying (read for example 1 and 2 on videnskab.dk).
Perhaps you have heard from a study of a Swedish professor showing you that the whole vaccine leads to cancer? That study was also sad.
If you help help, remove if you can represent on faxes, you can download the manifest at Videnskab.dk. It gives you tools to understand news and research results where you'll find them.
Effective factions are good for whole communities
Morten Ruhwald points out that although history of faxes was a great success, there are still major challenges and waiting.
"In Africa there is a huge demand for vacancies, and one has to contend with them to bring them out to people in the country, where people die for supply or infrastructure problems.
"In Denmark we have the reverse situation, that we have to teach people that they are still vaccinating against illness they have forgotten just because the vaccines are so effective," says Morten Ruhwald.
"Implements can prevent the suffering and death associated with infectious diseases such as pneumonia, diarrhea, growing cough, mare and polio. They can also help national priorities such as education and economic development to find a fetus," says the WHO.
"Wider access to factions is strong for realizing some of the world's goals from the UN. No other measure is just as cost effective," the email says.
The next big country wins
Vaccines, however, have not kept the world from disease. Dangerous diseases such as tuberculosis, malaria and HIV are really hard to overcome.
But now the most important thing is that, says Morten Ruhwald.
- Better and more HIV research and a combination of different types of treatments seem to lower the HIV epidemic. It is hoped that we can all help with HIV-related illnesses, particularly in Africa.
- A vaccination against malaria is being tested at various sites in Africa today. Every year, over 200 million subjects of malaria are divorced in every world. Almost 500,000 people have died.
Tuberculosis is more than malaria and HIV
The most common of the three diseases is tuberculosis.
Every year, 11 million people receive tuberculosis, also called TB. More than all ten doors, which are 1.8 million people in the last year.
The Vaccine Calmette, also called BCG, protects very well. It has been in use since & # 39; 20 and it is likely to release 120,000 children of all days, Morten Ruhwald says.
"In particular, it protects against serious cases, but although 85 percent of all new children's books are being eliminated in any world, it's not effective enough to control the TB epidemic," he points out.
Tuberculosis is hard to control because it has found a way to live people.
After infection, tuberculosis has been in the body for a long time in the air and breaks first when a person becomes weak. Often, patients with tuberculosis can enter for a long time.
Hurde makes vaccine for poor countries
Diseases such as malaria and tuberculosis usually affect people in development who cannot provide expensive vacuum. That the pharmaceutical industry is not interested, says Ruhwald.
– Therefore, as a public research proposal, we are developing new new vaccines, for example TB. When we show that a fax is working, the pharmaceutical industry can make it, he explains.
According to Ruhwald, the Danish National Serum Institute is the global control on the field.
The researchers are working on high pressure to develop new vaccine against tuberculosis. "New results indicate that we are in a direction," says Ruhwald.
However, some pharmaceutical companies are involved in the work. GSK has taken its own step to a fax. Both this faculty and the State Serum Institute are described in the New England Journal of Medicine.
According to Morten Ruhwald, the two studies together mark a milestone on the field.
