Top 10 Signs that Kids Shouldn't Get Vaccinated

When a child has a high fever, mothers should avoid vaccinating their little ones. According to health experts, it's absolutely not advisable to vaccinate a child while experiencing a fever, flu, especially when the child is acutely infected.

When a child is running a fever, with a body temperature exceeding 37.5 degrees Celsius, it's crucial to investigate the cause of the fever. Vaccination should only take place after the child has fully recovered from the fever, as injecting vaccines during an elevated body temperature may lead to reactions. Elevated body temperature can exacerbate the severity of the child's fever. Additionally, fever is often the first sign of acute infectious diseases such as the flu, measles, meningitis, hepatitis, etc. Vaccination not only accelerates the onset of illness but also worsens the condition, making it more difficult for doctors to diagnose. Furthermore, the antigenic components in vaccines and disease-causing bacteria will interact, affecting the child's immune response.

If a child has previously experienced shock and a severe reaction to a vaccine or any specific antibiotic, they should absolutely avoid this type in the future. However, if the adverse reaction is only to this particular vaccine, the child can still receive vaccinations for other diseases.

If a child has a history of allergies or severe reactions to vaccines, parents need to inform the doctor to assess the situation and provide appropriate recommendations. After vaccination, doctors usually ask parents to keep their child at the healthcare facility for at least 30 minutes to monitor their condition. If the child shows strong reactions during this time, the doctor will promptly intervene.

Some children suffer from egg allergies, preventing them from consuming eggs for a period. When someone is allergic to eggs, the body's immune system reacts excessively to proteins in eggs. If a child consumes a product containing eggs, the body automatically interprets these proteins as harmful agents in action. The immune system responds by acting more vigorously to push these invaders out. This reaction results in an allergy.

Some vaccines are produced from chicken egg embryos, such as measles and rabies vaccines. Therefore, if a child is allergic to eggs, they cannot receive that type of vaccine. Egg allergies may gradually diminish over time, so parents need to monitor until the child is no longer allergic to eggs before considering re-administering that specific vaccine.

When a child's immune system is compromised, mothers should refrain from vaccinating them. During this time, the child's internal condition is not optimal, and the vaccine injections may not provide adequate protection, rendering the vaccines ineffective.

In children with compromised immune systems, vaccines may have lower efficacy during periods of immunodeficiency. Therefore, vaccination should be postponed until the immune function is restored. If an inactivated vaccine has been administered during immunodeficiency, it should be revaccinated once the immune system has recovered. Individuals with weakened immune systems are often at high risk of adverse reactions after receiving live attenuated vaccines, as they lack the ability to suppress the replication of live attenuated viruses. Consequently, most children with compromised immune systems should avoid live vaccines (measles-mumps-rubella, chickenpox, live flu, shingles, yellow fever, BCG, rotavirus) as they may cause severe complications after vaccination.

Pneumonia in children is a severe respiratory infection. The disease can occur at any age, but children under 5 years old are the most commonly affected group, prone to serious complications and higher mortality. When children suffer from asthma or lung disease, respiratory-related illnesses should be approached with extreme caution during the annual flu vaccination. This is because the flu can pose serious difficulties for children with breathing issues.

Flu vaccines contain live viruses, which can potentially trigger an exacerbation of asthma. Therefore, in such cases, mothers need to be vigilant.

Cough or runny nose are symptoms of flu. When a child has a cough or runny nose, mothers should temporarily postpone the vaccination schedule to the next session. If the child is currently experiencing a cough, vaccinating at this time can lead to an elevated fever, posing a danger to the child.

If the child only has a mild cough and runny nose, and all other aspects are normal, there is no need to contraindicate vaccination. However, if the vaccine dose is not already overdue, it is best for the mother to wait until the child is completely healthy before vaccinating, as the immune response will be better.

For children undergoing chemotherapy or receiving immunosuppressive treatment for certain diseases, vaccination should also be avoided. Children who have recently used immune globulin products within 3 months (except for hepatitis B immune globulin) will temporarily delay the administration of live attenuated vaccines.

Children who are currently or have recently completed a high-dose corticosteroid treatment (oral or injection, equivalent to prednisone ≥ 2mg/kg/day), chemotherapy, or radiation therapy within 14 days also fall into the category of temporarily postponing live attenuated vaccine administration.

Acute diarrhea in children is a condition characterized by more frequent bowel movements, especially with changes in stool consistency, becoming loose or watery, sometimes with blood, lasting for about 14 days. Diarrhea is a common ailment in young children. When a child experiences excessive diarrhea leading to dehydration, weakness, and fatigue, it is advisable to avoid vaccination with certain vaccines that may trigger adverse reactions causing diarrhea. Hence, mothers need to take note of this.

However, in cases where a child has infrequent bowel movements, about 2-3 times per day, with no signs of fever, vomiting, or severe abdominal pain, it could be due to digestive disorders. In such instances, some doctors may still recommend vaccination for the child.

Some common infectious diseases in children such as skin inflammation, intestinal infections, respiratory infections, sepsis... can leave severe complications, significantly affecting the child's future development. Therefore, it is crucial to take the child for timely medical examination and treatment when dangerous signs of respiratory infections are observed.

When a child is suffering from infectious diseases, it is essential to cure the child before considering vaccination.

For preterm and underweight children with weakened immune systems, there is a high risk of contracting infectious diseases. Vaccination for these children is crucial. However, certain vaccines should be avoided, such as hepatitis B vaccine, tuberculosis vaccine, and others. Therefore, a thorough medical examination is necessary before vaccination to ensure the health of these children.

Severely malnourished children, those with severe rickets, or those with congenital immune deficiency should not be vaccinated. In these children, the immune system may be deficient or the development of immune organs may be impaired, so vaccination is not recommended.
