Why Do We Take Vaccines?

My name is Mohamed, and I am a student at the Faculty of Human Medicine at Sixth of October University in the Arab Republic of Egypt.

Immunization (Vaccines)

Vaccines are given to identify the immune system with the pathogen, in order to stimulate the production of antibodies.
Vaccines are of various types, and fight diseases in various ways.
Vaccines do not only protect individuals, but also communities as a whole.
The protection acquired through vaccination during pregnancy is a protection for the baby as well.
Failing to vaccinate children in due time puts them at risk of the targeted diseases.

Immunization defined:

Immunization is the cornerstone of public health. It is a way to protect people from infectious diseases. Vaccines

A vaccine contains dead or weakened bacteria or viruses (they are not capable of causing a disease) that are administered to individuals to encourage the immune system to recognize them and to consequently produce antibodies that can identify the germ early on. This allows the individual to fight the germ if it encounters it again, therefore preventing disease.
Vaccines are an easy and safe way to protect everyone since they are subject to safety tests before they are approved, and their outcomes are continuously monitored.

Target groups:
Pregnant women
The elderly
People with weakened immune systems due to cancer treatments
Patients with chronic diseases
Travelers heading to infected areas

Other names:
Vaccination, shots

Types of vaccines: They are several types of vaccines and each type helps the immune system fight a certain type of germs and the diseases they cause. They include:
Live-attenuated vaccines: They use an attenuated (or weakened) form of the germ that causes a disease. These vaccines are very similar to the natural infection and therefore help protect against the infection by creating a strong and long-lasting immune response. Just 1 or 2 doses (of most live vaccines) can provide a lifetime of protection against a germ and the disease it causes, e.g. MMR combined vaccine (measles, mumps, rubella), rotavirus, smallpox, chickenpox, yellow fever, shingles, and oral polio.
Inactivated vaccines: They use the dead version of the germ that causes a disease. The immunity (protection) they provide is usually not as strong as that provided by live vaccines. Therefore, several doses could also be needed over time to realize ongoing immunity against diseases, e.g. hepatitis A, influenza, polio, and rabies.
Subunit/conjugate vaccines: They use specific parts of the germ (e.g. protein, sugar, or the casing around the germ). Since these vaccines use only specific parts of the germ, they provide a very strong immune response that targets key parts of the germ. This type of vaccine can be used on almost everyone who needs it, including people with weakened immune systems and chronic health problems. However, one of their disadvantages is that booster shots may be necessary to get ongoing protection against diseases, e.g. Hib (haemophilus influenzae type b) disease, hepatitis B, HPV (human papillomavirus), Whooping cough, pneumococcal disease, and meningococcal disease.
Toxoid vaccines: They use the harmful product (toxin) made by the germ that causes a disease so that the immune system can fight this toxin rather than the germ. Like other vaccines, booster shots may be necessary to get ongoing protection against diseases, e.g. diphtheria, tetanus.

Why are vaccines important?
They give newborns a chance to grow healthily and to have a better life.
They eliminate infectious diseases that were once widespread or that can cause severe complications or death.
Vaccines not only protect the vaccinated individuals but entire communities as well.
They help reduce mortality rates.
They help prevent infectious diseases.
They stop the development of antibiotic resistance by reducing the use of antibiotics.
They help you travel safely and comfortably.
They provide economic benefit by saving on the costs of treating diseases.

What to expect when giving a toddler his/her first vaccine?
You can help the child by making the vaccination experience more positive and explaining to the child what is about to happen.

Before vaccination:
Remember to take the child’s immunization record card when visiting the doctor or the public health office. If your child doesn’t have a record, make sure to ask the healthcare provider about it.

During vaccination:
The doctor or nurse may ask you some questions about the child’s health such as if he/she suffers from allergies or health problems. Here are some tips to help the child during vaccination:
Relax: Children interact to their parents’ emotions and will be happier and more positive when the parents are relaxed.
Show affection: It is advised to hold the child and speak to him/her during the administration of the vaccine. Studies have found that children who are hugged and held scream less during an injection.
Breastfeed your baby: Breastfeeding before, during or after vaccination helps him/her stay comfortable and calm.
Distract your baby: A sweet voice or a calming touch can help calm a child. You can also hand the child his/her favorite toy or read him/her a story.

After vaccination:
Before you go home, remember to schedule the next appointment.
The first dose of immunization may be administered at birth with another dose given after two months. The child’s immunization record (vaccination card) should be received at the first appointment.
Remind the healthcare provider if they forget handy you the record.
Record the date of the next appointment in your mobile phone or calendar as soon as possible before you forget it.
Keep the child’s immunization record in a safe place to find it when necessary.
Bring the immunization record with you to every appointment to update it every time the child receives a vaccine.
Vaccines are a routine part of childcare. Their dates should be respected to protect your child’s health.

Vaccination-associated side effects
Most children feel fine after vaccination and should not exhibit any reaction in the least . Some may exhibit some side effects based on the type of vaccine. However, the benefits of vaccines far outweigh these mild and temporary side effects that often don’t require treatment. Side effects include:
Pain, redness or swelling around the injection area
Sleeping more than usual
Itchiness around the injection area
Mild rash
In rare cases, a severe allergic reaction may occur within a few minutes after vaccination.
The aforementioned reactions are considered normal, and usually last 12 to 24 hours.

Consequences of delayed vaccination
Any delay in vaccination may put the child at risk of developing the targeted diseases. The effect of a vaccine is perfect when it's taken on time and therefore the timely administration of vaccines is one among the parents’ key responsibilities. Vaccines provide children with lifelong protection from dangerous diseases.

Postponing vaccination
Vaccination can be postponed in the following cases:
Severe illness
For children receiving immunosuppressive drugs or treatments (chemotherapy, radiotherapy).
However, a child can be vaccinated if he/she is suffering from a mild illness, has a mild fever, or is taking antibiotics. It is advised to speak to the child’s doctor if you have any questions.

What to do when vaccination is forgotten?
Sometimes, you may forget to schedule a vaccination appointment. It is essential to check the immunization record and schedule an appointment with a healthcare provider as soon as possible. The healthcare provider will help you know which vaccines the child has had and which he/she still needs.

Children depend on their parents to be immunized.

When to see a doctor?
Before vaccination:
Severe allergic reaction to a previous vaccination.
Severe allergic reaction to one of the vaccine’s components.
Individuals with immunodeficiency problems cannot be vaccinated before consulting with a doctor.
Neurological disorders such as spasms or epilepsy.

After vaccination:
If the side effects are severe.
If the side effects don’t disappear.
If the child has spasms due to a fever.
If the child continues to cry for more than 3 hours.
If the child shivers or trembles.
If the child’s activity level significantly decreases.
If the swelling and redness in the injection area lasts more than 24 hours.

Immunization before traveling:
When traveling to another country, everyone is at risk of contracting diseases that can be prevented with vaccines. These could include diseases for which vaccines are not routinely administered. Therefore, it’s important to consult with a healthcare provider or to visit a travel health clinic six weeks before traveling. Certain vaccines may be recommended based on age, destination and travel plans.

Guidelines after vaccination Some side effects like loss of appetite or trouble sleeping don’t need treatment and disappear within 1 or 2 days. Some children may have to rest more after vaccination. Paracetamol drugs could also be used (e.g. Fevadol or Panadol) if a fever is detected. Instructions must be followed when administering the drug. Avoid giving aspirin to children. Regularly move the arm or leg (where the injection is taken). Consume many fluids and wear light and baggy clothes just in case of a fever. Avoid bathing the kid in cold water. Place cold, damp and clean compresses on the injection area to scale back swelling and redness.

Are vaccines safe?
The WHO has confirmed that vaccines are accurately tested to see their safety and are continuously monitored even after production.
If these diseases are rare, why does the kid got to be vaccinated?
Diseases that were once common have now become rare because of vaccines, but they still exist. Even one case of measles can spread quickly if vaccines aren’t given. it's difficult to spot who is carrying the germ and if a toddler is in danger .
Many of the diseases which will be prevented with vaccines haven't any cure. In some cases, children may die as a results of complications from the disease. the simplest protection is to immunize a toddler at the proper time.
How are vaccines approved?
Like all medicines, vaccines undergo a series of tests before they will be utilized in the dominion of Saudi Arabia . Several regulations are established to watch the availability , use and safety of vaccines. Side effects are reported by health care providers to public health officers at the Ministry of Health to streamline the handling of any unusual or unexpected side effects.
Are vaccines safer than the particular disease?
Yes. A child’s natural system can handle the weakened or dead germs contained in vaccines.
A child can experience a light fever or some pain within the arm after vaccination, but these side effects only last a couple of days and don't hinder daily activities.
However, if an unvaccinated child contracts the particular disease, the result might be dangerous or maybe deadly because active germs multiply rapidly and therefore the child’s system isn't prepared to defend against them.
Children got to receive vaccines at the required time.
Vaccines work best once they are given at the required times ranging from birth. Routine vaccination is provided freed from charge across the dominion .
A person must confirm that their vaccination is often up so far . this is often a life-long process.
Why should children be vaccinated at such a young age?
Vaccination schedules were designed to guard children from preventable diseases. they're given to children at a young age because it's during this early stage in their lives that they're susceptible to diseases with potentially dangerous consequences. However, if the vaccines are given on time, the kid will enjoy the simplest protection as quickly as possible.
When should children be vaccinated?
Children got to be vaccinated at different stages to supply them with complete protection. Some vaccines should tend quite once to build-up the child’s immunity.
Can a toddler receive quite one vaccine at an equivalent time?
Yes. Some vaccines are administered together to guard the kid from several diseases at an equivalent time. A child’s system is fascinating and may easily, safely and effectively, handle quite one vaccine at an equivalent time.
The healthcare provider will provide parents with information on the vaccines their child needs at every visit.
Where can someone get vaccinated?
Vaccines are available in the least health centers affiliated with the Ministry of Health and with the private sector.
What is the advantage of keeping a child’s vaccination up to date?
Up so far vaccination is required by schools. Children should have all of the specified vaccines before starting school or kindergarten. this is often important to assist stop the spread of dangerous diseases. A child’s immunization record is additionally useful when visiting a replacement doctor or when traveling.
