Maximum effect 2 weeks after recovery from flu
How many people would be willing to roll up their sleeves if I told them to get the flu shot after suffering from the flu this winter? Health authorities recommend that even if you are infected with Corona 19, it is better to get a vaccine to prevent re-infection after 4 months or more. Will this ‘formula’ work for the flu? The American media ‘Huffington Post’ reported on the 25th (local time).
Although the spread has weakened, the risk of catching the Corona virus 19 and the flu remains. This winter flu vaccine was made based on the prediction that it would be caused by two types A (H1N1 and H3N2) and two types B (Victoria and Yamagata). In fact, the common strain this winter is type A H3N2.
Before getting the flu shot, experts recommend getting the flu shot even if you already have it. “If you get the flu, you’re still susceptible to the other three types,” said Dr. Marie-Louise Landry of Yale University School of Medicine.
Dr said. John Swarzberg, clinical professor emeritus at the University of California, Berkeley School of Public Health, “Regardless of whether you’ve been vaccinated against the flu or not, you’re likely to get the virus multiple times.” Getting vaccinated is important,” he said, adding that it usually takes two weeks for the flu vaccine to be fully effective.
Although compulsory indoor mask wearing is expected to be lifted on the 30th, preventive measures against the flu and Corona 19 remain the same. It’s good to wear a mask in a crowded indoor environment, wash your hands often, and stay home if you feel sick.
In particular, it is best to get the flu vaccine if you have an underlying disease. Chronic diseases such as diabetes, asthma, and heart disease can be made worse by the flu. Serious complications requiring hospitalization or, in severe cases, can lead to death. There is also a report that when a diabetic patient is infected with influenza, the hospitalization rate is more than six times higher than that of the general population, and the mortality rate increases by more than 5-10%. In particular, patients with cardiovascular diseases such as myocardial infarction and arrhythmia increased their hospitalization rate more than sixfold due to the flu. According to the Korean Society of Infectious Diseases in 2019, influenza vaccination can prevent patients with chronic diseases such as diabetes, heart and lung disease from hospitalization and death by about 43-56%.
