Are there any side effects to the flu vaccine?

We all need to get vaccinations after we are born, and the flu vaccine is one of them. In fact, influenza is not a serious disease in our opinion. We only need a few days of rest to recover from the disease. But we must know that influenza is contagious and destructive, so getting the flu vaccine is very necessary. Are there any side effects of the flu vaccine?

Flu vaccine side effects

1. Local reactions: In placebo-controlled double-blind trials, the most common side effect of vaccination is pain at the injection site (affecting 10-64% of patients); this can last up to two days after the flu shot is given. Within 24 hours after vaccination, recipients may feel pain and tenderness at the injection site. These reactions are generally mild and short-lived. In most cases, they disappear on their own within 2 to 3 days and do not require further medical attention.

2. Mild adverse events: Overall, recipients tolerated the influenza vaccine well. These vaccines are inactivated, meaning they contain only inactivated viruses that are apparently incapable of causing disease. Therefore, respiratory illness after vaccination is an incidental illness unrelated to the influenza vaccine. Fourteen studies that analyzed by sex showed that women (both young and old) reported significantly more local reactions.

3. Systemic reactions: Mild systemic reactions may also occur. People who have not been previously exposed to the antigens in the vaccine (eg, children) may develop fever, malaise, and myalgias. These reactions occur within 6-12 hours after vaccination and generally last 1-2 days.

The influenza vaccine is a Category II vaccine, also known as an unplanned vaccine, and is paid for by the patient. So how much does a influenza vaccine cost?

The influenza vaccine is a self-paid vaccine and can be taken or not, depending on the physical condition of your baby. The imported vaccine costs about 80-85 yuan, and the domestically produced vaccine costs about 65-70 yuan. The influenza vaccine is a Class II vaccine, also called an unplanned vaccine, which refers to a vaccine that is taken voluntarily at one's own expense.

The diseases prevented by Category II vaccines are relatively less contagious, less prevalent and less harmful, but they can still cause certain harm to babies, especially those with poor resistance. The cost of Category II vaccines is borne by the person being vaccinated, so the country does not implement compulsory vaccination. You can choose whether to be vaccinated based on your own financial conditions and your baby's physical condition.

Things to note about influenza vaccination

1. Observe at the vaccination site for 15 to 30 minutes after vaccination.

2. The vaccination site should be kept dry and clean for 24 hours, and try not to bathe.

3. After vaccination, if the injection site becomes red, painful, sore, or has a low fever, these conditions are normal and will disappear naturally after 24 hours.

4. If symptoms such as persistent fever occur, you can go to the nearest hospital for medical treatment and report to the vaccination unit.
