Hello Friend

Many people have a total ignorance about influenza vaccines.

in rich countries it depends on each person if you want to use and buy these vaccines

On the other hand, in poor countries, the population is obliged to use them. So do not have the flu. They use it for prevention.

If it is useful, it is necessary not only.

The question should be

Why should people get vaccinated against influenza?

Influenza is a potentially serious disease that can lead to hospitalization and, in certain cases, even cause death. Each influenza season is different, and infection with the influenza virus can affect people in different ways. But millions of people get sick with influenza every year, hundreds of thousands are hospitalized, and thousands or tens of thousands die from flu-related causes every year. The annual seasonal influenza vaccine is the best way to protect against influenza. It has been demonstrated that vaccination has many benefits such as reducing the risk of illness due to influenza, hospitalizations and even the risk of pediatric deaths related to influenza.

How do influenza vaccines work?

Influenza vaccines cause antibodies to develop in the body approximately two weeks after vaccination. These antibodies provide protection against infection with the viruses included in the vaccine.

The vaccine against seasonal influenza protects against influenza viruses that, according to research, will be the most common next season. Traditional influenza vaccines (called "trivalent" vaccines) are manufactured to protect against the three influenza viruses: an influenza A (H1N1) virus, an influenza A (H3N2) virus, and an influenza virus. Influenza B. There are also influenza vaccines that protect against four viruses (called "tetravalent" vaccines). These vaccines provide protection against the same viruses as the trivalent vaccine plus an influenza B virus.

What types of influenza vaccines are available?

The CDC recommends the use of the influenza vaccine approved according to age, which includes the inactivated influenza vaccine [IIV], the recombinant influenza vaccine [RIC] and the live attenuated influenza virus vaccine [LAIV] ], during the 2018-2019 season. The nasal spray flu vaccine (LAIV) is again an option for vaccination during the 2018-2019 season.

Vaccines against trivalent (three-component) and tetravalent (four-component) influenza will be available.

Trivalent influenza vaccines include the following:

Trivalent injectable vaccines in standard doses (IIV3) that are manufactured using viruses grown in eggs. There are different injectable vaccines for influenza approved for different age groups. Most injectable flu vaccines are applied to the arm (muscle) with a needle. There is a formula of the trivalent vaccine that can be applied by means of a pressure injection, to people between 18 and 64 years old.

A trivalent vaccine in high dose, approved for people over 65 years.

A trivalent injectable influenza vaccine with adjuvant (an ingredient of a vaccine that helps trigger a stronger immune response in the patient's body), approved for people over 65 (new this season).

The tetravalent influenza vaccines include the following:

Injected injectable tetravalent influenza vaccines for different age groups, including children as young as 6 months.

A tetravalent injectable vaccine against influenza containing virus produced in cell culture, approved for administration in people over 4 years.

A recombinant tetravalent injectable vaccine approved for administration in people older than 18 years, including pregnant women (new this season).

A vaccine against quadrivalent influenza with live attenuated nasal spray virus (LAIV4) made with live attenuated (weakened) viruses.

Are some of these available influenza vaccines recommended over the others?

For the 2018-2019 influenza season, the Advisory Committee on Immunization Practices (ACIP) recommends annual influenza vaccination for all persons from 6 months of age and older with any approved influenza vaccine according to age, including the inactivated influenza vaccine (IIV), the recombinant influenza vaccine (RIV4) or the live attenuated influenza virus vaccine (LAIV4), without expressed preference for one vaccine over the other.

Who should get vaccinated this season?

Everyone 6 months of age or older should be vaccinated against influenza each season. This recommendation has been used since February 24, 2010 when the CDC's Advisory Committee on Immunization Practices (ACIP) voted in favor of "universal" influenza vaccination in the United States so that more people are protected against influenza. disease.

Vaccination to prevent influenza is particularly important for people who are at high risk for serious complications from the disease. See people at high risk of developing complications from influenza to see a complete list of factors related to age and health that increase the risk.

More information available in Who should get vaccinated against influenza.

Who should not receive the vaccine?

Different flu vaccines are approved for use in different age groups. In addition, some vaccines are not recommended for certain groups. Factors that determine whether a person is able to get vaccinated, or receive a particular vaccine, include age, health status (current and past) and any allergy to the influenza vaccine or its components.

People who can not receive the injectable vaccine against influenza

People who should talk to their doctor before receiving injectable flu vaccine

When should I get vaccinated?

You must be vaccinated against the flu before the flu begins to spread. After two weeks of vaccination, antibodies to protect against influenza begin to develop. The CDC recommends that people get vaccinated against influenza before the end of October. However, getting vaccinated later can still be beneficial and vaccination should continue to be offered throughout the influenza season, even in January and beyond.

Children who need two doses of the vaccine to be protected should begin the vaccination process much earlier because the two doses should be administered with an interval of at least four weeks.
