True or false ? 8 myths about flu vaccination

As every winter, the flu epidemic is in full swing

Outside of the gestures barriers, the only means of protection for the most fragile remains the influenza vaccine. But it does not imply the acceptance by the population, because of doubts about its adverse effects and, rightly so, on its effectiveness. A few days of the end of the vaccination campaign, The Figaro is back on the misconceptions about the influenza vaccination.

The flu vaccine does not protect 100% so there is no need to do vaccinerFaux. No vaccine is 100% effective and the flu vaccine is no exception to the rule.

It just allows you to reduce the risk of contracting the disease, by presenting the organization of the influenza virus, attenuated or inactivated. Its effectiveness may not be known before the epidemic period as the circulating viruses change every year. However, the flu vaccination is only effective if the virus that it contains correspond to the viruses in circulation.

Each year, the composition of the vaccine is changed accordingly, but it happens that the dominant virus is not included in it. In this case, the vaccine does not protect against the infection.

This was the case during the epidemic of the winter of 2014-2015: the circulating virus was found to be different from those selected for the vaccine. Even if it is not perfect, immunization is “the most effective way to prevent the disease or complications”, according to the WHO. It would prevent about 2000 deaths in elderly people each year in France, according to public Health France. ” READ ALSO – Influenza, the effectiveness is very variable to the vaccine I had the flu so that I am vaccinated(e)True. Even vaccinated, some people think having the flu. This can be explained in three ways. Either it is actually a flu: the person has not responded to the vaccine because it is not effective against the virus. Either it is not a flu but an infection caused by a virus non-influenza-like illness, the symptoms of which resemble those of the flu.

Last possibility: the person has been contaminated by the virus before the vaccine takes effect. Two weeks on average are needed for the body’s immune system develops protection against the microbe. This is not worth it to get vaccinated this year if it was the year dernièreFaux. It is necessary to be immunized each year for two reasons.

First of all, because the circulating viruses are rarely the same from one year to another. Then, because even if a virus returns in two consecutive years, the immune protection conferred by the vaccine only lasts 6 to 9 months approximately. Our immune system can fight only the virus grippeVrai and false.

Some people think that it is better to have the flu rather than get the vaccine, and this in order that our body’s immune system develops defenses over the long term.

It is true that most people recover in a few days, without medical treatment. If their health is only affected temporarily, these people may nevertheless pass the virus on to other, more at risk. This is the case of pregnant women, children under 5 years of age, the elderly, or individuals suffering from certain chronic diseases. In these individuals, the flu can lead to complications leading to death. The epidemic of 2016-2017 has been marked by a significant excess mortality related to the flu, due to the circulation of a strain of the virus particularly aggressive against older persons. Pregnant women and children should not be vaccinated because it is dangereuxFaux. On the contrary, the flu vaccine is recommended for all pregnant women regardless of the stage of pregnancy because it provides protection as well as their baby during its birth. Vaccination is also recommended for children over 6 months of age if they have a chronic disease at birth or risk factors for flu severe (prematurity, congenital heart disease, etc.

.). Antibiotics are used to fight the flu False. Antibiotics are of no help against the flu, because this infection is caused by a virus. However, the antibiotics only provide protection against bacterial infections.

For the time being, there is no effective treatment to treat the flu. Some homeopathic products can replace the vaccinFaux.

No homeopathic product can be considered as a vaccine, or can be called “vaccine homeopathic”. As pointed out in the superior Council of public hygiene in 2006, “the use of these homeopathic medicines instead of the flu vaccine is a loss of opportunity, particularly in individuals at high risk of complications”.

In January 2015, researchers from the Institute Cochrane reviewed 6 large-scale studies exploring the efficacy of Oscillococcinum, the flagship product of Boiron laboratories.

Their conclusion? “Our results do not exclude the possibility that Oscillococcinum could have a therapeutic effect, but given the low quality of the eligible studies, the evidence is not convincing”. In France, homeopathic products are exempt from providing evidence of their effectiveness, to obtain an authorisation for placing on the market, unlike drugs. The vaccine can cause Guillain BarréPlutôt False.

Guillain-Barré syndrome is a disease characterized by a disorder of peripheral nerves resulting in a total paralysis of the body. The flu is actually considered to be one of the risk factors as possible. According to the national security Agency of the drug (Msna), the occurrence of this syndrome is preceded in two-thirds of the cases an episode of infectious acute viral or bacterial three weeks to a month before the first symptoms. In 1976, the United States, the flu vaccine has, in turn, been implicated for the first time. It was a vaccine, whole virus, and without adjuvant. Since then, several studies have been performed and only one has demonstrated a very low risk of about 1 case per million vaccinees. According to the Msna, “(.

.. .. .) the ensemble of these data suggests that the proven risk of Guillain-Barre Syndrome resulting from flu is much higher than the uncertain risk of the occurrence of such a syndrome due to the vaccination”. . .
