World Influenza Day
November 1, 2021 is the fourth "World Influenza Day". The theme of this World Influenza Day is " influenza new crown, vaccines are used to prevent it", which aims to promote the popularization of influenza and new crown vaccine , strengthen international and domestic scientific exchanges on influenza and the prevention and control of new and recurring infectious diseases, and promote the preparation and response to prevention and control of new and recurring infectious diseases, as well as related scientific research.
Influenza virus, which endangers big health
Influenza is one of the oldest infectious diseases. From the Ancient Greek period to the present, there have been more than a dozen influenza pandemics recorded in history. Influenza is a major public health issue of concern around the world. It is prevalent around the world every year and can easily cause severe illness or death among high-risk groups such as children, the elderly and patients with chronic diseases. Although they are all called colds, influenza is much more lethal than common cold . According to data released by the World Health Organization , globally, it can cause 5% to 10% of adults and 20% to 30% of children to become ill. About 1 billion people are infected with influenza each year, including 3 million to 5 million severe cases and about 290,000 to 650,000 deaths.
According to Feng Luzhao, executive vice president of the School of Medicine and Public Health of Peking Union Medical College, influenza is the abbreviation of influenza, which is a respiratory infectious disease caused by the specific influenza virus . People may manifest symptoms such as fever, cough, sore throat after being infected with the flu, and may also be accompanied by some general symptoms, such as soreness and fatigue all over the body. "Of course, influenza can also cause some serious complications, which may sometimes be fatal for high-risk groups. Therefore, although influenza is a small virus, it is still quite harmful to the public."
from September to November every year
is the best time for influenza vaccine
2World Health Organization and authoritative agencies in various countries believe that getting influenza vaccination every year is the most effective way to prevent influenza. Influenza viruses are divided into types A, B, C and D, among which people are mainly infected with types A and B. Influenza vaccines need to be administered every year because influenza is a fickle virus that is constantly drifting against antigens. The mutated influenza virus reinfects the previously immune host, which can lead to repeated influenza epidemics. This is the root cause of seasonal flu and the need to get a flu vaccine every year.
Feng Luzhao reminds that is the best time for influenza vaccines every year, because the winter and spring peaks of seasonal influenza are usually from December to January of the following year, so it is best to get vaccinated before the peak arrives to produce antibodies. If the dose is not available within the optimal dose time, it can still be administered during the peak flu period. It should be noted that after getting influenza, you cannot get influenza vaccine in the acute phase and need to be cured before going to get vaccinated. In addition to being vaccinated, maintaining good living habits and protective measures can also effectively reduce the infection and transmission of influenza. For example, wear a mask in public places to avoid spreading the flu virus to others; abide by respiratory etiquette, use tissues or bends of sleeves to cover it when coughing or sneezing; pay attention to hand hygiene and wash your hands frequently.
These people should be given priority in influenza vaccine
At present, the global COVID-19 epidemic is still at a high level, and the continuous emergence of the new coronavirus mutant strains has brought more uncertainty to the development of the epidemic. The risk of the new coronavirus epidemic and respiratory infectious diseases such as influenza in the fall and winter of this year still exists, increasing the complexity and difficulty of prevention and control work. Therefore, the importance of seasonal influenza prevention and control is more prominent.
combined with the current global pandemic background of the new crown pneumonia epidemic, the "Technical Guidelines for the Prevention of Influenza Vaccine in China (2021-2022)" issued by the China Center for Disease Control and Prevention recommends that these populations give priority to influenza vaccine:
medical staff, including clinical treatment personnel, public health personnel, health quarantine personnel, etc.;
large-scale event participants and support personnel;
Vulnerable groups and employees in places such as nursing homes, long-term care institutions, welfare homes, etc.;
People in key places, such as teachers and students in childcare institutions, primary and secondary schools, detainees and staff in prison institutions, etc.;
Other high-risk groups in influenza, including home-risk elderly people aged 60 and above, children aged 6 months to 5 years, patients with chronic diseases, family members and caregivers of babies under 6 months of age, as well as pregnant women or women who are preparing to get pregnant during the flu season.
Chief expert of the immunization program of the Chinese Center for Disease Control and Prevention pointed out that influenza vaccination with is the main means to prevent influenza and an effective means. It is mainly reflected in two aspects: First, the occurrence of influenza can be prevented after receiving influenza vaccine. Second, after receiving influenza vaccine, the risk of comorbidities in high-risk groups can be reduced. People over 6 months old can get vaccinated if they do not have contraindications. For babies under 6 months of age, vaccination of people around the child, especially family members and caregivers, also has a certain protective effect on influenza in children under 6 months of age.
influenza vaccine and new coronavirus vaccine vaccination interval
should be greater than 14 days
At present, all parts of the country have successively carried out the vaccination of new coronavirus vaccine for minors and the enhanced vaccination of new coronavirus vaccine for adults. Now is the time to get the influenza vaccine. So, can the new coronavirus vaccine and influenza vaccine be vaccinated at the same time? Referring to the recommendations of my country's "Technical Guidelines for the Vaccination of New Coronavirus (First Edition)", the interval between influenza vaccine and new coronavirus vaccine should be greater than 14 days. You can get the new coronavirus vaccine 14 days after receiving the influenza vaccine; or get the influenza vaccine 14 days after completing the full vaccination procedure of the new coronavirus vaccine; or get the influenza vaccine between two doses of the new coronavirus vaccine, that is, get the influenza vaccine 14 days after receiving the first dose of the new coronavirus vaccine, and get the second dose of the new coronavirus vaccine 14 days after receiving the first dose of the new coronavirus vaccine, and get the second dose of the new coronavirus vaccine after 14 days. Choose two doses of the new coronavirus vaccine to get influenza vaccine, and the requirements for the number of doses and intervals of the new coronavirus vaccine must be followed.
It is worth noting that in order to prevent and control the new crown pneumonia epidemic, we must strictly follow the measures for epidemic prevention and control, go to vaccination according to the time period arranged by the vaccination clinic, reduce the number of accompanying people, and avoid staying in places where people gather. At the same time, we will cooperate with the epidemic prevention measures of "arrangement system, wearing masks, one-meter line, and frequent hand washing" to jointly maintain the safe environment for vaccination.
