Influenza Vaccine, Recognize Benefits to Side Effects

Influenza vaccine is the best protection against the flu especially in times of transition season susceptible to flu. Although it sounds like a mild disease, in fact influenza can cause major problems for some people.

Influenza is an acute viral and contagious viral disease that attacks the respiratory tract. There are two subtypes of influenza viruses: subtypes A and B. These viruses spread by air and physical contact such as shaking hands with flu sufferers. If left untreated, the disease may trigger relapsing comorbid diseases such as asthma, or secondary infection due to bacteria. Complications from flu are more likely to occur in elderly, pregnant women, children aged 6 months to 5 years, medical workers, and people with 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 toll from this disease reaches 500,000 cases. The highest mortality rate in children under 5 years of age due to the disease is caused by a lung infection. Symptoms of influenza can include fever, fever, sore throat, cough, runny nose, weakness, muscle aches, and headache.

Influenza infection can have a different impact on everyone. Although healthy, a person could have the flu and spread it to others. Symptoms can be mild but can also be severe to require hospitalization. And influenza vaccine is very useful to minimize the risk of flu and transmission. The Indonesian Pediatric Association (IDAI) recommends giving influenza vaccine for infants aged 6 months and above, unless they have a reason or medical condition that is not allowed to receive the vaccine.

Type of Influenza Vaccine You Need To Know

There are two types of influenza vaccine, namely trivalent and quadrivalent. Trivalent influenza vaccine is a vaccine containing two strains of the influenza A (H1N1 and H3N2) viruses, as well as the influenza B virus strain. And quadrivalent influenza vaccines contain two strains of the influenza A (H1N1 and H3N2) viruses, as well as two strains of influenza B.

The trivalent influenza vaccine includes:
  • The standard trivalent dose (IIV3) produced by using a virus planted in eggs. The vaccine is administered through an injection procedure, but can also be a jet injector for adults aged 18 to 64 years.
  • Trivalent high doses are reserved for older people (over 65 years).
  • Injectable trivalent infleunza vaccine made with additional ingredients may be given for people aged 65 and older.
  • Tissalent injections of egg-free combinations are approved for use in persons over 18 years of age.
Meanwhile, the quadrivalent influenza vaccine includes:
  • Quadrivalent flu injections are given for certain age groups.
  • Intradermal quadrivalent injection (injected into the skin instead of the muscle and using a smaller needle) is reserved for people aged 18 to 64 years.
  • Quadrivalent injections contain viruses grown in cell culture reserved for children aged 4 years and over.
Live influenza vaccines are available in dosage forms given through nasal sprays, and can be given to healthy people aged 2 to 49 years.

Influenza vaccine works by building antibodies in a person's body to fight influenza virus. Influenza vaccine takes about two weeks to work to create antibodies in a person's body.

In a cold climate country, the flu season occurs between December and February. To be effective, influenza vaccine is recommended to be given before December, may be given in November or October. While in tropical countries like Indonesia, flu epidemics can happen anytime. Therefore it is important to get influenza vaccine to prevent this disease.

The World Health Organization (WHO) recommends influenza vaccines to:
  • Children aged 6 months to 5 years.
  • The elderly (over 65 years).
  • Pregnant women.
  • Patients with chronic diseases.
  • Medical workers.
In order for effective and safe use of influenza vaccine, you are advised to consult a doctor before vaccinating. Especially if you have experienced an allergic reaction to an influenza vaccine before or have experienced Guillain-Barre syndrome that occurs after receiving an influenza vaccine.
