The scientific name of hepatitis B is hepatitis B virus, which is an infectious virus. In order to effectively control the spread of this virus. At present, our country implements compulsory planned immunization for newborns, and vaccinates hepatitis B vaccine at birth. The immune function of the newborn is not perfect. Once infected, it is difficult to clear the virus, which will become the carrier of hepatitis B virus. Therefore, the earlier the newborn is injected, the better. If it is injected within 24 hours, its immune function will reach more than 90%.
Is hepatitis B vaccine intramuscular injection
The baby has just been born and its body is so fragile. Every new mother feels heartbroken when she sees the doctor deeply injecting a needle into the baby's small body. Isn't all vaccines given subcutaneously? Why do we have to dig so deep?
No, different vaccines have different injection methods in neonatal vaccines. Subcutaneous vaccines include: BCG vaccine, rubella vaccine, measles vaccine, mumps vaccine, meningococcal vaccine, Japanese encephalitis vaccine, hepatitis A vaccine, varicella vaccine, mumps vaccine, leprosy vaccine, mumps vaccine, etc.
The intramuscular vaccines include: DPT, DPT, hepatitis B, rabies vaccine and influenza vaccine.
Hepatitis B vaccine is just one kind of intramuscular injection. The vaccination site for newborns is in the outer muscle of the front thigh, and for children and adults, it is in the middle muscle of the deltoid muscle of the upper arm.
The difference between intramuscular injection and subcutaneous injection
Intradermal injection is the process of injecting medication into the skin below the epidermis, usually above the dermis layer, but not into the subcutaneous tissue. Subcutaneous injection, which absorbs quickly but causes pain, is commonly used as a precursor to skin allergy testing, vaccination, or local anesthesia.
Muscle injection is a commonly used method of drug injection therapy, which refers to injecting medication into muscle tissue through a syringe to achieve the goal of treating diseases. The location of intramuscular injection should be deeper than subcutaneous injection, reaching deep into the muscle tissue., So it looks like the doctor is very aggressive.
In order to achieve the absorption efficiency and immune effect of hepatitis B vaccine, our country implements intramuscular injection. For newborns, the first choice is the muscle injection at the front and outside of the thigh, and the second choice is the muscle injection at the upper arm deltoid. Compared with the hip muscle injection, these two parts have more developed muscles, fewer blood vessels, and a thin subcutaneous fat layer, which are the best parts for muscle injection of hepatitis B vaccine.
