What is the importance of vaccination?

A vaccine activates our immune system without making us sick. Many dangerous infectious diseases can be prevented in this simple and effective way. A vaccine activates our immune system without making us sick.

What is the importance of vaccination Class 9?

It helps in the stimulation of the immune system and to identify the invaded microbes as the foreign agent and destroy it so that the immune system can be recognized and to destroy any microorganism encountered later. You need to understand the difference between vaccinations, vaccines, and immunizations.

Which vaccines are most important?

Recommended vaccinations:

• Chickenpox (varicella) vaccine.
• Diphtheria, tetanus, and pertussis vaccine (DTaP)
• Hepatitis A vaccine (HepA)
• Hepatitis B vaccine (HepB)
• Hib vaccine.
• Human papillomavirus (HPV) vaccine.
• Influenza vaccine.
• Measles, mumps, and rubella vaccine (MMR)

Which vaccine is given at birth?

All babies should get the first shot of hepatitis B vaccine within first 12 hours after birth. This shot acts as a safety net, reducing the risk of getting the disease from you or family members who may not know they are infected with hepatitis B.

What is the basic principle of vaccination?

Vaccination is one of the most effective medical interventions to reduce morbidity and mortality of infectious diseases. The main principle of vaccination is the proactive induction of a protective immune response by mimicking the natural interaction of an infectious pathogen (bacteria, viruses, etc.)

What is the concept of vaccination?

Vaccination: The act of introducing a vaccine into the body to produce immunity to a specific disease. Immunization: A process by which a person becomes protected against a disease through vaccination. This term is often used interchangeably with vaccination or inoculation.

How our body fights pathogens which is also basic principle for vaccinating our body?

A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.

What happens when a vaccine is injected into the body?

Your immune system reacts to the vaccine in a similar way that it would if it were being invaded by the disease — by making antibodies. The antibodies destroy the vaccine germs just as they would the disease germs — like a training exercise. Then they stay in your body, giving you immunity.

How does injection work in the body?

Intramuscular injections, abbreviated as IM, deliver a substance deep into a muscle, where they are quickly absorbed by the blood vessels into systemic circulation. Common injection sites include the deltoid, vastus lateralis, and ventrogluteal muscles.

What are the 3 types of injections?

The three main routes are intradermal (ID) injection, subcutaneous (SC) injection and intramuscular (IM) injection. Each type targets a different skin layer: Subcutaneous injections are administered in the fat layer, underneath the skin. Intramuscular injections are delivered into the muscle.

How do I choose a needle for injection?

Intramuscular (IM) injections The needle length and gauge are the same as when the deltoid muscle is used, i.e., 1″–1½” length, 22–25 gauge. You should choose needle length based on the weight of your adult patients, as follows: Adults weighing less than 130 lbs (60 kg): Use of a 1″ needle is recommended.

What size needle do you use for insulin?

The board recommends 4-, 5-, and 6-mm needles for all adult patients regardless of their BMI. It is also recommends inserting 4-, 5-, and 6-mm needles at a 90-degree angle and that, if needed, longer needles should be injected with either a skinfold or a 45-degree angle to avoid intramuscular injection of insulin.

How long is a vaccine needle?

Adults, 19 years and older Most adolescents and adults will require a 1- to 1.5-inch (25–38 mm) needle to ensure intramuscular administration.

What size needle is used for pneumonia vaccine?

Use a 22-25 gauge needle. Choose the injection site and needle length appropriate to the person’s age and body mass. Skin stretched tight, subcutaneous tissue not bunched. Needle Length: Proper needle length and technique are necessary to deliver the vaccine to the muscle.

What route are vaccines given?

Vaccine administration routes include:

• Oral route: administered by mouth.
• Subcutaneous route: injected into the area just beneath the skin into the fatty, connective tissue.
• Intramuscular route: injected into muscle tissue.
• Intradermal route: injected into layers of the skin.
• Intranasal route: administered into the nose.

What size needle is used for infants?

For infants, children and teens Note: For neonates (first 28 days of life) and preterm infants, a 5/8″ needle is recommended if the skin is stretched flat between the thumb and forefinger and the needle is inserted at a 90-degree angle to the skin.

Where do you give your baby a shot?

The anterolateral thigh is the preferred site for IM injection in infants under 12 months of age. Medications are injected into the bulkiest part of the vastus lateralis thigh muscle, which is the junction of the upper and middle thirds of this muscle.

How many mL Can you give IM in pediatrics?

Injections should be given 6 cm below the acromion process. The maximum volume should not exceed 1 mL. If the skin is stretched flat, a 1/2 inch needle is sufficient.

What are the needle sizes for injections?

For example, 25G ½ refers to a 25 gauge, ½ inch-long needle. Longer needles (½ inch or longer) are commonly used for intramuscular injections, while shorter (shorter than ½ inch) needles are more often used for intravenous injections.

What size needle is used for blood donation?

16 to 17 gauge

What size needle is used for IV injections?

5/8 inch

How do you give an injection?

2. Remove the cap.
3. Draw air into the syringe.
4. Insert air into the vial.
5. Withdraw the medication.
6. Remove air bubbles.
7. Insert the needle.
8. Check for blood.

How can I make injections less painful?

Minimizing the Pain

1. If you can, make sure your medicine is at room temperature.
2. Wait until the alcohol you used to clean where you’re going to inject is dry.
3. Always use a new needle.
4. Get the air bubbles out of the syringe.
5. Make sure the needle is lined up right going in and coming out.
6. Stick the needle in quickly.

Where is the least painful place to get an injection?

Subcutaneous injections tend to be less painful than intramuscular injections because the needles are smaller and do not have to push through as much tissue. Children and people who fear needles may still have issues with these injections that can cause anxiety.

What is the most painful place to get an injection?

Shots given in muscles — like the deltoid in the upper arm where flu shots are usually given — tend to be more painful than ones that aren’t injected into the muscle, Stewart said. “Muscles have little tight fibers, and if you separate it by sticking a needle in there, you can cause an inflammatory reaction,” she said.

How can I stop my fear of shots?

Tips for Overcoming a Fear of Needles

1. Reframe your thinking. It may sound easier said than done, but consider this: phobias are, by definition, extreme irrational fears.
2. Try not to worry.
3. Get your doctor or nurse involved.
4. Face your fear.
5. Consider therapy.
6. Get the shot.
