1. Influenza Vaccine
Influenza vaccine is the best protection against flu, especially when the transition season
is vulnerable to causing flu. Although it sounds like a mild disease, in fact, influenza can
cause big problems for some people.
Influenza is an acute and contagious viral infectious disease that attacks the respiratory tract.
There are two subtypes of influenza viruses, namely, subtype A and B. This virus spreads
through the air and physical contact such as shaking hands with flu sufferers. If left untreated,
this disease can trigger the recurrence of comorbidities such as asthma, or secondary
infections due to bacteria. Complications due to flu are more at risk for the elderly, pregnant
women, children aged 6 months to 5 years, medical workers, and sufferers of certain diseases,
such as HIV/AIDS, chronic heart or lung disease, and asthma.
According to the World Health Organization (WHO), the incidence of influenza reaches 5
million cases per year and the death rate from this disease reaches 500,000 cases. The highest
mortality rate in children under the age of 5 due to this disease is caused by lung infections.

2. Symptoms of influenza can include fever, fever, sore throat, cough, runny nose, weakness,
muscle pain, and headache.
Influenza infections can have a different impact on everyone. Although healthy, a person can
get a cold and pass it on to other people. The symptoms can be mild but can also be severe to
require hospital care. And the influenza vaccine is very useful to minimize the risk of getting
a cold and transmission. The Indonesian Pediatrician Association (IDA) recommends giving
influenza vaccines to infants aged 6 months and above, except those who have medical
reasons or conditions that are not allowed to receive this vaccine.
The Type of Influenza Vaccine You Need to
Know
There are two types of influenza vaccines, namely trivalent and quadrivalent. The trivalent
influenza vaccine is a vaccine containing two strains of influenza A (H1N1 and H3N2)
viruses, as well as influenza B virus strains. And the quadrivalent influenza vaccine contains
two strains of influenza A (H1N1 and H3N2) viruses and two strains of influenza B virus.
The trivalent influenza vaccine includes:
 The standard trivalent dose (IIV3) is produced using a virus planted in eggs. This
vaccine is given through an injection procedure, but it can also be a jet injector for
adults aged 18 to 64 years.
 Trivalent high doses are specifically for elderly people (over 65 years).
 A trivalent injection influenza vaccine made with additional ingredients can be
given to people aged 65 years and over.
 Egg-free combination trivalent injections are approved to be given to people aged
18 years and over.
Meanwhile, quadrivalent influenza vaccines include:
 Injections of influenza quadrivalent are given for certain age groups.
 Intradermal quadrivalent injections (which are injected into the skin instead of into
the muscles and use smaller needles) are intended for people aged 18 to 64 years.

3.  Quadrivalent injections contain viruses that grow in cell cultures destined for
children aged 4 years and over.
The direct flu vaccine is available in the form given by nasal spray and can be given to
healthy people aged between 2 to 49 years.
Influenza vaccine works by building antibodies in a person's body to fight influenza viruses.
The influenza vaccine takes about two weeks to work creating antibodies in a person's body.
In cold climate countries, flu season occurs between December and February. To be effective,
influenza vaccines are recommended before December, can be given in November or
October. While in tropical countries like Indonesia, flu outbreaks can occur at any time.
Therefore it is important to get an influenza vaccine to prevent this disease.
The World Health Organization (WHO) recommends
influenza vaccines for:
 Children aged 6 months to 5 years.
 Elderly people (more than 65 years).
 Pregnant women.
 Patients with chronic diseases.
 Medical workers.
For effective and safe use of influenza vaccines, you are advised to consult a doctor before
vaccinating. Especially if you have had an allergy to a flu vaccine before or have experienced
Guillain-Barre syndrome that occurs after receiving a flu vaccine.
Side Effects of Influenza Vaccines
There are various side effects that can be caused related to influenza vaccine
administration. Common side effects include:
 Pain, redness, and swelling in the area injected.
 Fever.
 Nausea.
 Breathless
 Hoarseness.
 Swelling around the eyes or lips.
 Tired, dizzy, and pale face.
 Heartbeat.
 Changes in behavior.
 Fainted.
 Runny nose.

4.  Muscle aches.
 Gag.
 Sore throat.
If you experience any of these reactions after receiving the influenza vaccine, contact your
doctor immediately to get further treatment. To prevent influenza disease, in addition to
vaccines you can do several things, such as reducing contact with sick people, resting at
home when you are sick, eating and drinking enough, using a mask to avoid spreading the
virus when you cough or sneeze, and get used to to wash hands with soap and clean water.
