The new crown is so fierce around the world, why do you have to get an influenza vaccine?

Since this year's outbreak of the new crown, the new crown vaccine has been the focus of major media and people's attention.
Although the current outbreak in China is basically alleviated, but from time to time there are still cases of distribution, in addition, the outbreak abroad is still not optimistic, watching into the autumn of September, "the new crown epidemic may have a second wave of risk" and other related topics from time to time appeared in the major media news, almost the eyes of the world are focusing on the emergence of the new crown vaccine.
although the new crown is so fierce around the world, let's not forget that before the new crown, the absolute protagonist of respiratory infections in autumn and winter - influenza (flu for short).
remember the hotly debated "Beijing Middle-Year" in 2017? At that time, this article left a lot of people left a "cold is not a small thing" impressed.
We are about to enter the peak season of influenza, this year under the threat of the new crown, we can not forget the protection of influenza, although the new crown vaccine is still under development, but the production and development of influenza vaccine has been very mature, take this opportunity, let us relive the truth about the influenza vaccine again! Q What is an influenza virus? Many people may wonder, since they are "colds", how the flu is so fierce, and even a district of a "cold" can become a life-threatening threat to some patients pay the price of life? Influenza is short for influenza, as defined in the just-released Influenza Treatment Programme (2018 edition): an acute respiratory infection caused by an influenza virus that causes outbreaks and pandemics worldwide.
human influenza virus belongs to the positive adhesive virus family, including influenza A (A), B, C (C) and D (D) influenza virus genus.
, only influenza A and B viruses can cause important clinical diseases and seasonal epidemics in humans.
Q get the flu vaccine? Influenza is a very serious disease that can lead to hospitalization or even death.
even young and strong, you can still be knocked down by the flu and become a source of infection.
flu season lasts from November to March.
annual flu vaccination is the best way to reduce the risk and spread of influenza.
does the Q flu vaccine work? Protective antibodies are usually produced 2 weeks after influenza vaccination to protect against influenza strains contained in the vaccine.
seasonal influenza vaccine is based on studies predicting the most likely flu virus for the next flu season, with different regions and years.
Traditional trialic influenza vaccines are used to prevent influenza A H1N1, influenza A H3N2 and influenza B/Yamagata (BY) strains;
Q should I get the flu vaccine? > 6 months of age and adults should be vaccinated against influenza each year.
is particularly recommended for high-risk patients: the elderly, children, pregnant women, chronically ill people and medical personnel and other high-risk influenza population.

Need to consult a doctor before vaccination: no more than 500 gg/ml of egg white protein residue in the flu vaccine and those who are allergic to vaccine ingredients; those with a history of Gilambare syndrome; and those who are unwell before vaccination.
is the best time to vaccinate Q? What if I miss it? Vaccination is usually recommended from September to October, i.e. before the flu season begins, as it usually takes two weeks for the vaccine to produce antibodies to protect against it.
but vaccinations throughout the flu season can benefit even if they are late.
to be particularly cautioned that early vaccination is required as influenza vaccinations for children between 6 months and 3 years of age require two injections and are four weeks apart.
Q Where do I get what kind of vaccine? Vaccines recommended by the World Health Organization for 2017-2018 (including lysate vaccines and recombinant sub-unit vaccines) are not recommended for nasal spray detoxifying live vaccines (in the past few seasons, protection is slightly less effective than needle inactivated vaccines; recommended only in some populations).
the world, influenza vaccine to lyse vaccine-based, more mature technology, there are many sub-unit vaccines, sub-unit vaccine prevention effect is slightly less than lysed vaccine, safety slightly better than lysed vaccine.
China's market, there is no imported influenza vaccine, domestic lysevered vaccine is the absolute main force, the domestic vaccine is mainly for injection with tri-price and four-price flu lysed vaccine, rare sub-unit vaccine, are non-living vaccines.
have flu vaccination points in various community health centres and can go to the consultation.
Q Why should I get the flu vaccine every year? There are two reasons: first, the protective antibodies produced by the influenza vaccine decrease over time, lose their protective effect, and the annual vaccination keeps the antibodies at their optimal level;
strains used to produce vaccines also need to be changed to enhance protection.
have antibodies right after I get the flu shot at Q? No! After vaccination, it takes about 2 weeks to produce the corresponding antibodies, so it needs to be done before the flu season.
Q I'm a high-risk group for influenza, but it's 2 weeks after vaccination to produce antibodies, what am I going to do now? Drug prevention may be considered.
drug prevention, however, is not a substitute for vaccination and can only be used as an emergency temporary precaution for people at high risk of severe influenza who are not vaccinated or have not been immunized after vaccination.
can be used with esthave, etc. under the guidance of a doctor.
Q I've got the flu vaccine, can I get the flu? That's right! Even if vaccinated, there is still a certain probability of getting the flu, but the probability has been greatly reduced.
the role of influenza vaccine is related to a number of factors, including the age of the person vaccinated, health status, whether the strain used to make the vaccine "matches" this year's epidemic strain, such as the WHO recommended A/Brisbane/59/2007 in the influenza vaccine (H1N1), a human-hosted influenza strain with the serial number 59 isolated in Brisbane in 2007, would have the best prevention results if this year's strain had been "matched".
, even if you get the flu vaccine, the protection of lynx cannot be taken lightly.
after the experience of the new crown, it is necessary that everyone for the protection of respiratory infections has been very familiar: hand hygiene, wearing a mask, avoid rubbing eyes, discomfort in time to seek medical attention, these basic operations can be maintained! Q I've had the flu this year, do I need to get vaccinated? Need! Because the flu virus you've been infected with isn't necessarily the same as this year's flu season, and it's not necessarily the same as the strain that protects you from the flu vaccine, it's still necessary to get the flu vaccine.
adverse reactions I may have after getting the flu vaccine from Q? You won't get the flu after getting the flu vaccine, but you may have some adverse reactions.
these symptoms are usually mild and short-lived.
for those with myocardial vaccination, possible discomforts include soreness, redness, swelling, low fever, etc.
For children with nasal spray, possible discomforts include runny nose, wheezing, headache, vomiting, muscle soreness, fever, and for adults, relatively few discomforts may occur, including runny nose, headache, sore throat, and cough.
the vast majority of patients with mild symptoms and recover within 1 to 2 days.
very few patients may experience serious adverse reactions, such as severe allergic reactions.
