Precautions for Japanese encephalitis vaccine injection

Everyone has heard of Japanese encephalitis! Japanese encephalitis (JE) is an acute infectious disease transmitted by the JE virus through mosquitoes and is prevalent among humans and animals. The Japanese encephalitis vaccine is a vaccine for preventing Japanese encephalitis and will have obvious effects. So what should we pay attention to when injecting Japanese encephalitis vaccine?

Most people do not react to the Japanese encephalitis vaccine. Only a few children experience local redness, swelling and pain after the injection, which disappears within 1 to 2 days. Fever is rare and is generally below 38°C. A few people have subjective symptoms such as dizziness, headache, and discomfort. Occasionally, the incidence of skin rash, angioedema and anaphylactic shock increases with the number of vaccinations. It usually occurs 10 to 30 minutes after injection and rarely lasts more than 24 hours. This type of vaccination reaction is more common in subjects who receive repeated booster injections, especially in children over 7 years old. People who use Japanese encephalitis vaccine should pay attention to fever and acute diseases; serious chronic diseases; brain and nervous system diseases; allergic diseases, and use with caution if you have a history of allergies to antibiotics or vaccines.

Other things to note

⑴ Vaccines that are turbid, discolored (yellowed), or have cracks or foreign matter in the ampoule should not be used.

⑵ To reduce the pain during injection, add an appropriate amount of sodium bisulfite to the vaccine. When the vaccine changes from orange to yellow, it can be injected.

⑶ Rest for a while on site after vaccination to prevent side effects.

⑷ 1:1000 epinephrine should be available for emergency use in case of occasional shock.

⑸ Most areas of my country are endemic for Japanese encephalitis, and the latent infection rate among the population is very high. People over 10 years old have generally acquired immunity due to latent infection, so there is no need to vaccinate again.

Therefore, when getting vaccinated in the future, you should consider your own physical factors and do not get vaccinated blindly. If you are not clear about your physical condition, it is recommended that you go to the hospital for a physical examination and take measures after determining your physical factors.
