The flu vaccine, also called a flu vaccine or flu vaccine, protects against different types of influenza viruses that are responsible for the development of influenza. However, since this virus undergoes many mutations over time, it becomes increasingly resistant, therefore the vaccine must be reorganized each year to protect vaccinated against new mutations in the virus.
The vaccine is usually injected into the arm and helps the body develop flu immunity, thus preventing flu-related complications such as pneumonia or heart problems, as well as hospitalizations and deaths. For him, the vaccine expels people, a small dose of inactive influenza virus, which is enough to “penetrate” the immune system and defend the body in case of contact with the live virus.
- The vaccine is indicated in people at higher risk of becoming infected with the flu virus and developing symptoms and complications.
- But often in people with weakened immune systems.
- Which groups are most at risk:.
In addition, individuals and others deprived of their release should also be vaccinated, in particular because of the conditions of the places where they are located, which facilitates the transmission of diseases.
The flu vaccine protects against different groups of influenza, including H1N1. For vaccines administered free of charge by the public health system, normally protected against 3 types of viruses, these are influenza A (H1N1), influenza A (H3N2) and influenza type B, so it is a trivalent vaccine; however, there is also a tetravalent vaccine that also protects against another type of influenza B virus.
In all cases, the vaccine does not protect against any type of coronavirus, including the cause of COVID-19 infection.
The flu vaccine provides public health services in each country, usually to risk groups, and is administered in health care during immunization campaigns, however, non-risk group members can go to private clinics, where they paid, if the position is vacant.
The group vaccine lasts between 6 and 12 months, so it should be given each year, especially during the year. In addition, because influenza viruses have rapid mutations, the new vaccine is used to ensure that the body is protected from new types of viruses that appear during the year.
After administration, the vaccine begins to be effective for 2 to 4 weeks, so it cannot prevent an ongoing flu.
Ideally, the vaccine should be given up to 4 weeks before flu symptoms appear, however, in case of illness, it is advisable to wait until this episode resolves and symptoms disappear before getting vaccinated to prevent natural flu symptoms from developing. confused with a reaction to the vaccine, for example.
The vaccine will protect the body from another possible influenza virus infection.
Some side effects that may result from vaccine application include the development of cold symptoms such as flaking or rhinitis, as well as whether you could develop a reaction at the site of application of the vaccine, such as pain, swelling and redness. If applicable, it is recommended to apply some ice in place for a few minutes during the day to reduce inflammation.
In rare cases, headaches, fatigue, muscle aches, weakness, high blood pressure and abnormal bleeding may occur.
The vaccine is contraindicated in people with bleeding, Guillain-Barré syndrome, blood clotting problems such as hemophilia or skin spots that occur easily, neurological disorders or brain diseases.
In addition, it should not be applied to people with latex allergy, a weakened immune system, as in the case of those receiving cancer treatment and taking blood thinners, as well as during childbirth and lactation.
During the embargo, women’s bodies are more vulnerable to infections, so there are many opportunities to catch the flu, that is why they are risk groups and therefore must be vaccinated in the proposed health offers.
