Unplanned vaccines generally include varicella vaccine, HIB vaccine (Haemophilus influenzae type B vaccine), rotavirus vaccine, influenza vaccine, 23-valent pneumococcal vaccine, hemorrhagic fever vaccine, rabies vaccine, etc. 1. Chickenpox vaccination Role of vaccination: Chickenpox is a highly contagious disease, and in kindergartens, if one person gets sick, the whole kindergarten baby may be infected. The disease can cause fever and skin blisters and pustules, and may cause complications such as pneumonia and meningitis, or complicate bacterial infections. If you contract chickenpox before the age of 1.5 years, you may also hide a lifelong crisis of recurrent shingles (commonly known as skin snakes). When your baby goes to kindergarten, complete the vaccination. Some kindergartens will ask when you enter the kindergarten that you will only be accepted into the kindergarten if you have received the varicella vaccination. Varicella vaccination is the best way to prevent chickenpox. After one vaccination, the conversion rate of serum antibody in the body can reach 98.6% and can be maintained for 2 years. 2, HIB vaccine (Haemophilus influenzae type B vaccine) vaccination role: Haemophilus influenzae type b infection is a serious infectious disease, HIB is a common bacteria parasitic in the upper whistle tract, children under 5 years of age are most vulnerable to infection. If a child before the age of 5 is infected, it often causes meningitis, pneumonia, osteomyelitis and other fatal reactions. The Haemophilus influenzae vaccine has been included as a routine vaccination in many European and American countries. It is recommended that parents should choose to vaccinate their children with this vaccine as long as the family’s financial condition permits, and the age of vaccination should be above 2 months, generally less than 6 months old should receive 3 doses at an interval of 1-2 months, and then a booster at 1.5 years old, while children older than 6 months to 1 year old should receive only 2 doses at an interval of 1-2 months and a booster at 1.5 years old. 1-5 years old children should receive only one injection. 3, rotavirus vaccine Vaccination role: pediatric autumn diarrhea, also known as pediatric rotavirus gastroenteritis. The diarrhea that occurs in babies in autumn is mainly caused by rotavirus. This vaccine mainly prevents diarrhea caused by rotavirus infection in babies, with a protection rate of about 60%-70%, which cannot completely prevent babies from getting the disease, but is more effective in reducing the symptoms of diarrhea in babies. It is recommended that mothers who want their babies to receive this vaccination should do so when their babies are 6 months old, because this disease is most likely to invade babies aged 6 months to 2 years old. 4.Influenza vaccination The role of vaccination: 6-35 months is the baby’s own immune function is developing and maturing stage, this age baby’s resistance to external viruses is weaker than older babies, when encountering the flu epidemic, more likely to be infected with the flu. Influenza can easily lead to complications such as pneumonia, otitis media and myocarditis, so babies should be vaccinated against influenza. Generally speaking, infants and toddlers aged 6 months to 3 years need a child’s dose of the vaccine, with the first injection and a second one after an interval of 4 weeks. 5, hepatitis A vaccine Hepatitis A is a type of viral hepatitis, a gastrointestinal infection caused by the hepatitis A virus contaminating food and water through the patient’s feces. It is highly contagious, widespread, and most common in children and adolescents. The onset of the disease is mainly in the spring and autumn. In addition to personal hygiene, the most effective way to prevent hepatitis A is to get vaccinated against it. All children and adults who are susceptible to the hepatitis A virus and who are at least 1 year old should be vaccinated. 6.23-valent pneumococcal vaccine The role of vaccination: pneumococcus can cause a variety of diseases, such as meningitis, otitis media, bronchitis, arthritis, etc., with a high mortality rate. There are more than 90 kinds of pneumococci, and 23-valent pneumococcal vaccine is selected from 23 kinds of most pathogenic germs, and its antigenic polysaccharide is purified and mixed in proportion to make the vaccine, which can cover 85%-90% of pneumococcal infestation. 7.Hemorrhagic fever vaccine Vaccination role: Applicable to susceptible people in epidemic hemorrhagic fever infected areas, vaccination according to the 0, 14 days procedure, half-yearly booster a shot. Hemorrhagic fever disease profile: The early symptoms of epidemic hemorrhagic fever are fever, including headache and lumbago, in addition to which flushing of the face, neck and chest may occur. The disease can lead to kidney damage and invasion of multiple organs and tissues throughout the body, and there is no specific drug treatment for the time being, so the focus is on prevention in the disaster area. 8, rabies vaccination Vaccination role: the world has not yet an effective treatment for rabies, the morbidity and mortality rate of almost 100%. Therefore, all bites or scratches by sick animals or animals with poison should be immediately injected with rabies vaccine. Babies who are severely bitten, such as wounds on the head and face, bites on multiple parts of the body, deep bites, etc., should be combined with anti-rabies virus serum. There are several misconceptions about vaccination: Misconception 1: Some vaccines require several shots within one year of age, in fact, one shot is enough to protect your baby. Truth: One shot is not enough for many vaccines, and some require several shots to give adequate immune protection (for example, acellular pertussis requires three shots within one year of age). Some need to be given annually to deal with changing germs (for example, the flu vaccine needs to be given every year before flu season begins). And some need to be given when the baby becomes an adult because the effects of some vaccines slowly diminish over time (for example, acellular pertussis needs to be given once more at the age of 4 to 6 years). Myth 2: Babies cannot be vaccinated if they have a cold. Truth: Many parents feel that a sick baby will have greater side effects from vaccines. In fact, studies have found that if it is a mild cold it is not affected. Of course, if your baby has a high fever of 39 degrees and an ear infection, it is definitely not suitable for vaccination. Of course, the vaccine itself can have side effects, such as fever, rash, redness and swelling at the vaccination site. However, these reactions are not common, and even if they occur, they are normal, so parents should not panic too much. After vaccination, if hives, high fever of 39 degrees or more, or convulsions occur, it is necessary to seek immediate medical attention. Myth 3: My baby’s immune system is still developing and cannot receive so many vaccines. Truth: It may seem like a lot of vaccines for a one-year-old baby, but studies have shown that there are actually countless bacteria/viruses in life that exercise your baby’s immune system every day, from bacteria on the floor (she ate a cookie that fell on the floor), to viruses in food, and airborne dust or cold viruses, and a healthy baby can safely handle these challenges. The germs in vaccines seem very insignificant compared to these, and let’s not forget that these insignificant germs make your baby’s immune system stronger. Myth #4: If all other children are vaccinated, my baby doesn’t need it. Truth: This is a typical “herd theory”, because if everyone around me is vaccinated, there will be no viruses/bacteria around me. However, this so-called “herd theory” has limitations. This theory only applies to certain diseases, and it assumes that at least 90-95 percent of the people around you are fully immunized. This is almost impossible to achieve because there are many babies who are still a few shots short of immunity (i.e. not fully immunized) because they are still small. And if everyone is so lucky, the surrounding area will not be safe at all. Myth #5: Vaccines are just injecting bacteria into your baby’s body, and my baby will get this disease because of the vaccine. Truth: Most of the vaccines available today are inactivated vaccines, which means that your baby will not get the flu because of the flu vaccine, nor will he or she get whooping cough because of the pertussis vaccine. Even if some vaccines are for bacteria with very low activity (such as measles), the chance of causing disease is very, very low, and these have been clinically proven on a large scale. Myth 6: Vaccines can cause autism or other developmental problems in babies.
