Earlier this month, a single case in measles was found in Oslo. In February last year, three cases of measles in eastern Norway were reported. The disease was not infected and he was abroad. The World Health Organization (WHO) expresses concern that parents are saving the children alone.

We asked five questions and answers to an expert on vaccines.

Expert: Tone Fredsvik Gregers

Education: A main theme is the biology and experience of cells (ie Scient.) In cellular biology

Jobs as: The biologist at the University of Oslo and the author of the book Everything you need to have a vaccine

1. How do vaccines work?

When it is open to a panel (pathogenic organism, unemployment) and sickness, anyone with a normal system of protection will respond to the bacterium or virus to the body surviving. It is known as building a defense response. After a period of illness, one is re-introduced.

When a defense response is built, a memory response will be created at the same time as specially designed memorial cells. The cells in the cells that protect the memory stick are special if they are open to later on. So the next time you are the same sound at the same panels, your immune system will recognize you and your body will leave the path without being ill. This is the basis for its defense, the definition of the biologist.

– All vaccines use this special feature of the defense system. The vaccines are vaccinated against the vaccine, but are available in a format that is weakened, dead or in pieces. When you get these versions of the pathogen into your body, your immune system can understand this as a foreign – just like a natural pathogen. But, as the body is weakened, dead or in pieces, you are unwell. However, the defensive position is built and it is a reminder that you choose to protect against the disease in the future, Gregers says.

This family will set the weekly menu for non-plastic options. Here are their suggestions.

2. Why do you need to have vaccines several times?

– For good protection and lasting protection over a long period of time, most vaccines need to be taken several times. He is keen to train the defense system to create a strong and stable reminder, Gregers says.

The vaccine must be given twice: first at 15 months, and then if the child is about 11 years old. Full vaccine and measles protection is only after two doses.

– Diphtheria, tetanus, whooping cough and polio are given five times through the vaccination program and are brought together. Even a non-natural disease with the patches gives life-long protection, so it is recommended that these vaccines give every 10 years after the last dose in the program. The vaccine needs to be made on her own.

3. Can the vaccines be either fatal or harmful in any way?

– Number. By keeping in mind the panes are weak, dead or tiny, they don't give you the diseases, and they are not deadly too. In some very unusual cases, they can cause effects. However, all vaccines in the childhood immunization program are completely safe. As these vaccines have been given for many years in so many countries, without having a negative positive impact, I have to answer that question.

It follows:

– There are many worries about living money in vaccines, but then it is important to be aware that there are no money in the Norwegian vaccines today. This applies to all vaccines, including your flu vaccine. Mercury was removed from a childhood immunization in 1997.

– Wouldn't it be better to take natural defenses than vaccination?

– There are natural defenses, whether you have shown an infection in a natural disease or a vaccine. The only difference is that you avoid ill with a vaccine. You also avoid problems that it might be and the possible diseases it could lead to. The risk of getting more vaccines than being at risk from serious side effects is higher.

4. What side effects may the vaccines have?

When you get a vaccine, you dry your skin. This includes the fact that the body believes you have a stance that is moving into effect.

– Compare with a tile in your finger: The slab has bacteria in it, the finger gets back, painful and painful, just as it gets cells protecting the site. The same goes for vaccines: The immune system puts millions of protective cells on the site where the syringe is sent and you go hard and swollen, Gregers says.

For example, if you have tetanus vaccine, you often get a little more stiff and sore in the arm, but it's not dangerous and it lasts a few days. Some of them also feel a feeling of sickness with fever and shame after immunization, but it is only that the body believes that it is attacked and provides a defense response. T

“Once you have the vaccination you should always stay with your health care professional for 10-15 minutes to make sure you don't have an impact,” said Gregers.

– People with a real egg should be careful when they get chicken eggs, such as the flu vaccine. However, this is rarely a problem and is relevant only to people with some ingredients in the vaccine.

5. What are the possible effects of getting a vaccine, both to you and to others?

– When it comes to yourself, it's so by giving you vaccination that you miss out sick. Child vaccines protect against very dangerous diseases that may be fatal or cause serious problems and problems, according to Gregers. T

She uses the virus as an example of: t

The virus of measles attacks the cells in the defense system. Even though you are suffering from measles, you will have a more permanent defenses system after that. You will therefore be more likely to suffer from other viral diseases and to have a bacterial infection, which may be the result of a very severe immune system. In the case of bacteria, you may need to go through an antibiotic course which may be avoided if you were immunized. Therefore, vaccination is also a step against an unnecessary use of antibiotics.

By vaccination, you also protect other people who for different reasons may not be vaccinated. You may be small, sick and elderly. The vaccines work as a firewall, and that's what we call it a protective herd.

– Even if you see the virus, you will have a security system that will stop the virus entering cells and creating new viruses. When you don't create new viruses, you can spread them no further. In other words, you will not be infectious when you have been immunized, although many people think it is, Gregers says, adding:

– But if you do that No immunization and tenancy, it takes a few days or weeks from attending the virus until you get the symptoms. During this time you are infectious without your knowledge. Then there's no reason to argue that you live at home if you grow ill because it is still too late, Gregers says.
