What vaccines are likely to cause fever?

Many babies will develop many uncomfortable symptoms after vaccination, especially fever, which is very troubling for mothers. This article will explain the precautions related to hepatitis B vaccine. In fact, some symptoms that appear after vaccination are side effects of the vaccine and are normal. If you have a fever, as long as the temperature is not high, you can use some common methods to lower your body temperature, such as ice compresses, drinking more hot water and sweating, etc. If the condition is serious, you should seek medical attention as soon as possible.

Generally speaking, fever is normal and parents do not need to worry too much. If the baby only has a low fever, parents can use physical cooling methods. If the baby has a high fever that does not subside, the baby should seek medical attention in time to prevent sequelae.

Does the hepatitis B vaccine cause fever?

If this phenomenon occurs, the vaccine will cause adverse reactions. If it is just a low fever, it is not a big deal. Give the baby more water to drink and wipe the body with warm water. Close the doors and windows when wiping the body. It will usually last for two or three days. Just observe and see. In this case, don't rush to give your baby medicine. You should observe for a period of time. If you are worried, you can go to a regular hospital for examination and consultation.

If your baby has a fever while receiving the hepatitis B vaccine, it may be a process of self-adjustment. Don't rush to take medicine as soon as you have a fever. It is best to observe the baby first. The most important thing is to let the baby replenish water in time and get more rest. It is generally not recommended to give babies antibiotics within three days after receiving the hepatitis B vaccine, otherwise it will easily cause the hepatitis B vaccine to become ineffective and fail to achieve the purpose of hepatitis B prevention.

Generally speaking, getting the hepatitis B vaccine will not affect your daily work and life. Only a few people will experience redness, swelling, nodules, pain at the injection site, soreness or fever in the arm, etc. If your baby has a fever after getting the hepatitis B vaccine, do not use antipyretics blindly. Wipe your baby's sweat in time, change his clothes in time, or use a towel to pad his back to prevent him from catching a cold. You need to go to a regular liver disease hospital to get the hepatitis B vaccine.

Things to note when getting hepatitis B vaccine

1. Check before injection

Hepatitis B vaccine should not be administered during various acute diseases or acute attacks of chronic diseases. Those with abnormal liver function should not be vaccinated with hepatitis B vaccine first. Find out the cause and receive treatment, and then vaccinate after liver function returns to normal.

2. Check the effect of vaccination (i.e. check whether the vaccination was successful)

After most vaccinations, there is no guarantee that everyone will be successfully vaccinated. Hepatitis B vaccine is no exception. Hepatitis B vaccine often has the possibility of failure due to improper storage, irregular vaccination or a weak individual's immune system. Therefore, after completing the full course of hepatitis B vaccination, you must go to the hospital to check the five hepatitis B tests to verify whether the vaccination was successful.

3. Regularly check the titer of hepatitis B surface antibody (i.e. check resistance)

After receiving the hepatitis B vaccine, the body will produce protective antibody surface antibody HBsAb. However, the HBsAb titer will disappear in the body year by year, that is, there is a half-life. Studies have shown that when the HBsAb titer is less than 10 international units, the surface antibody HBsAb is not sufficient to resist the invasion of hepatitis B virus. Therefore, you must go to the hospital regularly to check the HBsAb titer after completing the hepatitis B vaccination.

When hepatitis B vaccination fails or the antibody titer is too low, you can choose to re-vaccinate or get a booster shot. For specific solutions, you can consult a doctor based on the results of the five hepatitis B tests and the antibody titer.
