How a vaccine works?

The h1n1 virus known as the swine flu is not practically a new virus, as diseases with a pandemic component were known before. Some of those viruses are malaria, the Spanish flu, and even the aviary flu that ravaged the world a few years ago. The most efficient method to prevent the infestation with h1n1 is the vaccine. However, in the case of the swine flu, the efficiency of this vaccine was contested by researchers, especially because of the numerous secondary effects reported. However, the virus does less damage to people that were already vaccinated against the flu, and the pandemic spreading can be significantly reduced. One of the most successful vaccination campaigns was conducted in Africa against malaria, and the results were encouraging.


Stimulation of the prophylactic vaccination against h1n1


The most effective method to prevent the swine flu is represented by the prophylactic vaccination, which has to stimulate the production of antibodies capable of fighting the virus. Through vaccination, the organism gains the capacity to neutralize the viral particles of the pandemic virus, at the level of the respiratory system. However, the vaccines as well as the results are different in case of malaria, let’s say, than the result in the case of h1n1 vaccination.


How are the swine flu vaccines tested?


The anti-virus vaccines are made with alive, but weakened strains of the respective pandemic virus. The H1N1 vaccines are made on the base of the culture of the embryonic eggs, just like in the case of malaria, although the culture can be obtained directly on the eggs. There are four kinds of flu vaccines, with different reactions and effects over h1n1.


The vaccines with an inactive virus – this vaccine against the swine flu has integral viral particles of the virus that are already dead. The body is able to produce antibodies to fight the disease, and it is considered one of the most effective vaccination methods against any pandemic disease, including malaria.

The sub unitary h1n1 vaccine with or without additives

Alive vaccines with weak swine flu components – while this method is considered the most effective, as the body must fight the alive virus, it is also dangerous. It is just like in football or any other sport: sometimes, the sparring partner defeats the champion, even if this happens once every 1000 cases.


How to find the approved and safe h1n1 vaccine


EMEA is the authority that has the role of evaluating and approving different types of swine flu vaccines. If you want to take a vaccine of this kind, ask the doctor if the vaccine is approved by this authority, and also ask what the principle of the vaccine is.


What is the composition of an anti-virus pandemic vaccine?


Besides the components that have the role to immunize the body against infections such as malaria and h1n1, a vaccine must also contain other substances that increase the general resistance of the immune system, and conserving substances.


The respective substances are designed to prevent the mutations of the swine flu. It is important, as one of the most terrifying aspects of a new virus of this kind is its increased capacity to adapt to unfriendly environments.


Besides the pandemic protecting substances, an h1n1 vaccine contains conserving substances that prevent the vaccine from being infested.


What groups of people have priority for the swine flu vaccine?


The production of anti-virus vaccines against pandemic diseases such as malaria is continuous, but the demand for those vaccines was always greater then the producing capacity. Whenever h1n1 is detected, the medical staff in the respective area has priority for vaccination. As soon as all those people are immune to the swine flu, they will have the responsibility to determine the impact of the virus, possible causes and the evolution of the pandemic virus.


The next categories of people that have priority for h1n1 vaccination are the people with an increased risk of catching the swine flu. This means children, people that were proven as having a weakened immune system and old persons. However, the local authorities have the responsibility to establish the vaccination priorities against any virus, so the institutions with a national interest would continue to function. In other words, in a country that depends on a single nuclear power plant, once the medical staff was vaccinated, the people working in the respective plant will be the next priority for vaccination against the pandemic disease.
