| Can the flu vaccine not fight? Doctor: Not everyone is suitable |
Before taking the child to the hospital for flu shots, you need to be prepared. First, we must carefully observe the child's physical and mental condition. If the child is found to have some "snoring", it may be ill. The time for vaccination should be postponed. The second is to take a bath in advance, because the wound can not be wet for a period of time after the inoculation, and at the same time, the child is replaced with soft and wide underwear to facilitate the injection. The third is to ensure rest and avoid fasting.
After vaccination, be sure to stay in the hospital for 30 minutes to prevent severe allergic reactions. Many children may have symptoms such as low fever, headache, and fatigue. Individual children may also have rash, nausea, vomiting, and diarrhea. These are normal phenomena. Just let the child rest properly, drink plenty of water, avoid cold, pay attention to nutrition, one or two. The reaction will disappear after the day. When the local reaction is heavy, use a clean towel for hot compressing, 4 to 5 times a day, 10 to 15 minutes each time. If the local reaction cannot resolve in a short time, you should go to the hospital as soon as possible.
Infants and young children between the ages of 6 months and 3 years are very vulnerable to the flu virus. Therefore, if the child has no contraindications, he should be vaccinated. Children from 6 months to 35 months need to be vaccinated twice, 0.25 ml each time, with at least 4 weeks between them.
Flu vaccine is not suitable for everyone
When the flu is in epidemic, it will take effect one or two weeks after vaccination, so it is best to vaccinate in advance.
Children, elderly and infirm, chronically ill patients, etc. are susceptible to influenza, and vaccination is recommended. Generally, it is only required to be vaccinated once a year, and antibodies can be produced 10 to 15 days after vaccination. At one month, the antibody reaches a peak and immunity can last for one year.
It should be noted that the flu vaccine is not suitable for vaccination for everyone. People who are banned from inoculation are allergic to eggs or other components of the vaccine; patients with Guillain-Barre syndrome; pregnant women within 3 months of pregnancy; patients with acute febrile illness; acute exacerbations of chronic diseases Period; those with mental illness, severe epilepsy and schizophrenia; those with severe allergies; those younger than 6 months; those under 12 years of age who cannot use the whole virus inactivated vaccine.
Many people believe that patients with cardiovascular disease are unbearable for vaccination. In this regard, the director of the Cardiovascular Department of the Rocket General Hospital said that in fact, this will not cause any signs of deterioration, on the contrary, patients with cardiovascular disease must be vaccinated. The reason is that the flu itself can cause a variety of complications, and these complications often appear in patients with cardiovascular disease.
Do not take medicine easily with a mild cold
Although the flu and the cold are similar, the causes and harms are quite different.
The common cold is an acute respiratory infection caused by various pathogens such as rhinovirus and coronavirus, and can occur all year round. The main cause of the flu is the influenza virus, which can be divided into three types: A, B, and C. Among them, the type A antigen is highly susceptible to mutation, so the influenza pandemic is caused by the type A virus, and the type B and type C are locally small or Distribute.
The flu often causes diseases such as primary viral pneumonia, secondary bacterial pneumonia, myocarditis, pericarditis, nephritis, encephalitis, acute and chronic bronchitis, and asthma. According to information released by the World Health Organization, between 600 million and 1.2 billion people worldwide are infected with the flu every year, and 250,000 to 500,000 people die from the flu. Therefore, the flu is a serious threat to human health and should not be underestimated.
In addition, many people take medicines when they have symptoms of a cold, which is not scientific. If you only have symptoms such as sneezing, coughing, runny nose and mild cough, you do not need to take the medicine. Because the human body has the ability to cure colds naturally, taking medicine while catching a cold will produce resistance. During a mild cold, pay attention to rest to improve your body's ability to resist disease. At the same time, drink warm water and exercise properly.
Is it necessary to get a flu shot?
A: The clinical manifestations of influenza are fever; headache, body aches and pains; fear of cold; more with respiratory symptoms, such as runny nose and dry cough. The flu can also cause diarrhea and vomiting. Older people and people with various chronic diseases or weak constitutions are prone to serious complications after influenza. One is secondary bacterial infections such as pharyngitis, otitis media, sinusitis, bronchitis, especially pneumonia. Chronic diseases, including heart disease, pneumonia, kidney disease and diabetes, lead to the failure of the corresponding organ function. For adults, elderly people or children who are sick, the flu can cause serious consequences and even death. There is currently no specific antiviral drug, and influenza vaccine is the most effective measure to prevent influenza in the world.
How effective is the protection of the flu vaccine?
A: Relevant research shows that the protective effect of flu vaccine for children aged 1-15 is 77%-91%; flu vaccine for adults under 65 can reduce 87% of flu-related hospitalization; after vaccination for people over 60 years old, protection The efficacy of influenza-related respiratory diseases is 58%; vaccination against influenza in the elderly can reduce 27%-70% of influenza and pneumonia-related hospitalizations.
Is it safe to get a flu shot? Are there any side effects?
A: It is very safe to use the flu vaccine for people who are not afflicted with contraindications. In the past 30 years of use, there have been no reports of serious side effects, and the incidence of local reactions in vaccination is also very low.
Low fever may occur after inoculation, and there may be slight redness, pain, erythema, induration, etc. at the injection site, but these are temporary phenomena and the incidence is very low, so don't worry too much. These reactions usually disappear within 1-2 days and generally do not require special treatment. Others may have common skin reactions such as itching, urticaria, non-specific rash; very few vaccinated subjects have neuralgia, paresthesia, convulsions, transient thrombocytopenia, severe allergic reactions (such as anaphylactic shock), vasculitis Adverse reactions such as nervous system diseases; when these reactions occur, they should be reported to the inoculation unit in time, to the medical unit for treatment, and if necessary, for treatment.
After getting the flu vaccine, will you get the flu again?
A: The study shows that 70%-95% of influenza vaccinators are protected from the flu. If the virus strain changes during the flu season, the vaccine may not provide effective protection, but this condition is less common.
