What should I do if my baby has a fever after being vaccinated?
Experts: Seek medical treatment and ask for "foreign aid" over 38.5 ℃
The 4-month-old baby was vaccinated with diazepam and polio vaccine, and the body temperature suddenly rose to 38 ° C the next day. The novice Baoma panicked at home: What is the problem with the baby, should you run to the hospital?
Through the "online consultation" on the Internet, I learned that I can observe at home first, but Baoma still thought: Why does my baby have a fever after being vaccinated and will it affect the baby's health? What should parents do?
Listen to the analysis of Liu Hua, a child health expert at Wuhan Children's Hospital:
[Question] Why does my baby have a fever after being vaccinated?
This starts with the principle of the vaccine. The vaccine is equivalent to a weak pathogen. After being orally or injected into the human body, the body's immune system will immediately recognize the pathogen and produce corresponding protective antibodies. When you encounter similar pathogens in the future, your body will automatically start the defense function.
If your baby resists the "invading" traces of pathogens, the immune system will release some heat sources after activation, which may cause a low fever. A brief low fever is normal.
In the case of "unbeatable" or "too powerful", a high fever above 38.5 ° C may also occur, and you must quickly seek medical treatment and ask for "foreign assistance".
[Focus] The "fever index" of these vaccines is relatively high
Doctors have inferred from clinical experience that these types of vaccines are more likely to cause fever in babies after vaccination: diabetic vaccine, measles, meningococcal vaccine, and Japanese encephalitis vaccine.
However, whether you get fever after getting the vaccine varies from person to person, which has something to do with your baby's health and nutritional status.
In theory, the vast majority of vaccine responses are mild and do not cause serious harm.
[Distinguish] In these cases, you must rush to the hospital
In summary, after the baby is vaccinated, if a low fever below 38.5 ° C occurs within 24 hours, or if there is a slight irritability, crying, vomiting, diarrhea, etc., it is a mild reaction after vaccination, and it will disappear after one or two days. worry.
Parents only need to drink more water, rest more, and dress appropriately (to help dissipate heat). For diet, we recommend lightly digestible foods such as porridge, noodles, and egg custard.
However, parents should pay special attention to taking the baby to the doctor if the baby has the following conditions:
· High fever above 38.5 ℃, no fever after 48 hours. Especially for babies younger than 3 months or with a history of febrile seizures;
The baby has poor mental condition, decreased urination, dehydration, abdominal pain, severe vomiting and diarrhea, convulsions, severe cough, and difficulty breathing.
[Protection] Be careful before vaccination, do not scrub after vaccination
Liu Hua reminds parents that it is necessary to choose the right time for vaccination and to do protective work after vaccination. In the special period of the moment, take protection when you go out with your baby, try not to let your baby touch public items in public places, and go home to clean and disinfect in time.
Before vaccination
1. Bring your baby's vaccination certificate and free vaccination service manual;
2. Bathe your baby one or two days before vaccination and keep the vaccination site clean;
3. Put on clean and loose clothes to make it easy to expose the inoculation site;
4. Try to avoid vaccinating your baby during sleep;
5. Explain the health status of your baby to your doctor. If you are unwell, check with your doctor how much time you need to make up.
After vaccination
1. Stay in hospital for 30 minutes after vaccination before leaving. Thirty minutes after taking sugar pills or rotavirus vaccine, breastfeed, water or other hot food;
2. Please dress your baby when you leave, and be careful not to get cold while blowing hair;
3. Avoid mutton, fish, shrimp, seafood and other diets on the day of inoculation;
4. Do not scrub the inoculated area when bathing within 24 hours to avoid getting wet to prevent infection;
