during autumnAnd with Weather variations The chances of catching the flu are increasing, and for this reason public health officials are calling for early vaccination, stressing that… Flu vaccine Annuals are the most effective way to protect against disease and reduce the severity of the disease.
According to the Indianexpress website, influenza is a respiratory disease caused by influenza viruses that spread easily from person to person, and these viruses mainly affect the nose, throat and lungs.
Flu symptoms usually include fever, chills and chillsMuscle pain Cough and congestionRunny nose Headache and fatigue.
And unlike Cold Usually, often slowly developing, flu tends to appear suddenly and can lead to serious problems such as: Smallpox Bronchitis and even death, especially in high-risk groups such as young children, the elderly over 65, pregnant women, and those with chronic illnesses such as asthma, diabetes and heart disease .
Influenza is mainly spread through droplets when an infected person coughs, sneezes or talks. These droplets can remain on surfaces where the virus can live for up to 48 hours. .
Preventive measures such as washing hands, wearing masks, and staying at home when symptoms appear help limit the spread of the virus.
How does the flu vaccine work?
Flu vaccines are updated every year to protect against flu viruses that research suggests will be the most common in the coming season. Vaccines contain inactivated or weakened flu viruses. influenza, which cannot cause the flu but helps the immune system to develop antibodies. These antibodies protect against infection when exposed to live flu viruses.
It usually takes about two weeks after getting the vaccine to build immunity, which is why public health officials recommend getting vaccinated in the fall, before flu levels start to drop. get up This gives people time to develop immunity before the flu appears.
Benefits of influenza vaccine
One of the most important benefits of the flu vaccine is that it greatly reduces the risk of serious illness, hospitalization and death from the flu. spread of the virus in the community This is particularly important to protect vulnerable groups such as the elderly, children, pregnant women, and individuals with chronic health conditions.
In addition, widespread influenza vaccination helps prevent the health care system from becoming overwhelmed, especially in a year when other respiratory viruses such as respiratory syncytial virus (RSV ) and COVID-19 is still circulating. By reducing the overall number of hospitalizations due to the flu, vaccines also free up health care resources to meet other urgent needs.
Why should I get vaccinated every year?
One of the unique challenges of the flu virus is that the virus is constantly moving. Due to these frequent changes, the immunity acquired by the body from last year’s vaccine will not give it complete protection this season. That’s why the flu vaccine is updated every year to match the most common types of the virus.
Even if a person received the flu vaccine in the previous year, it is important to get the vaccine again to maintain protection against new viral strains that are circulating in the population. Flu vaccines are reformulated each year based on global research data collected by organizations such as the World Health Organization and the Centers for Disease Control and Prevention in the United States.
Some people believe that the flu vaccine can cause the flu, but this is a myth that inactive viruses in the flu vaccine cannot cause illness. After receiving the vaccine, some people may experience mild side effects such as pain at the injection site or a low-grade fever, but these symptoms are short-lived and much worse than the flu. to blow completely.
