Influenza Vaccines: Helping Parents and Caregivers Make Informed Decisions

Influenza Vaccines: Helping Parents and Caregivers Make Informed Decisions

What are Influenza Vaccines?

Influenza vaccines protect against various strains of influenza viruses, which are common causes of acute respiratory illnesses. Influenza A and B viruses are the most common types, with influenza A viruses being the principal cause of larger epidemics and worldwide pandemics. Influenza C virus is common but rarely causes severe disease in humans. In tropical regions like Kenya, influenza can cause disease throughout the year, often displaying a biannual pattern.

How the Vaccines Work

Influenza vaccines work by stimulating your immune system to produce antibodies against specific strains of influenza viruses. This helps the body recognize and fight off the viruses if exposed in the future, providing protection against the disease.

Vaccinating your child against influenza is crucial because it can prevent severe illness, hospitalization, and long-term health complications. By ensuring your child is vaccinated, you are protecting them from influenza and contributing to the overall health of the community.

Benefits

  • Prevention of Severe Illness: Influenza vaccines can prevent severe illness, hospitalization, and death.
  • Reduced Morbidity and Mortality: Vaccination helps reduce morbidity in children and mortality in the elderly and high-risk groups.
  • Protection for High-Risk Groups: Older persons and those with underlying medical conditions are at higher risk of severe disease and benefit significantly from vaccination.

Risks and Side Effects

Risks and Side Effects

  • Common Side Effects: These include soreness at the injection site, low-grade fever, and muscle aches.
  • Rare but Serious Side Effects: Allergic reactions are rare but possible.

  • Live Attenuated Influenza Vaccine (LAIV): Administered as a nasal spray.

What to Expect During and After Vaccination

During vaccination, your child may experience mild discomfort from the injection or nasal spray. After vaccination, some children may experience common side effects such as soreness at the injection site, low-grade fever, or muscle aches.

  • Dosage: One dose is recommended, but children aged 6 months to 8 years who have not received a seasonal influenza vaccine during the previous influenza season should receive 2 doses administered at least 4 weeks apart.

Live Attenuated Influenza Vaccines (LAIV)

  • Age Group: Should be used only in persons aged 2–49 years who do not have underlying medical conditions.
  • Dosage: Given as a nasal spray, one dose only; but children aged 2–8 years who have not received a seasonal influenza vaccine during the previous influenza season should receive 2 doses, at least 4 weeks apart.
  • Contraindications: Do not administer LAIV to pregnant women.

Target Groups

Influenza vaccination is recommended every year, particularly for high-risk groups, including:

  • Children <1 year of age
  • Elderly persons, above 65 years
  • Elderly non-institutionalized individuals suffering from chronic conditions such as pulmonary or cardiovascular illness, metabolic diseases including diabetes mellitus and renal dysfunction, and various types of immune-suppression including persons with AIDS and transplant recipients

Special Influenza Vaccines

When needed, special influenza vaccines are made available in response to the emergence of newer viruses or combinations of existing viruses. Some of these viruses include avian influenza (H5N1) and H1N1 viruses. Guidelines on the use of these vaccines will be provided by the Ministry of Health as necessary.
