Updated Influenza Vaccine Recommendations by AAP

Updated Influenza Vaccine Recommendations by AAP

A new policy statement issued by the American Academy of Pediatrics (AAP) recommends that all children aged 6 months and older should receive an injectable influenza vaccine as soon as it becomes available.

As per the Centers for Disease Control and Prevention (CDC) report, the 2017-2018 flu season was one of the most severe – excluding pandemics – on record. A total of 180 children died of influenza-associated deaths with thousands more hospitalized (as of August 25, 2018). The CDC says that children who did not receive flu vaccination accounted for ~80% of the deaths.

“The flu virus is common – and unpredictable. It can cause serious complications even in healthy children,” said Flor M. Munoz, MD, FAAP, member of the AAP Committee on Infectious Diseases. “Being immunized reduces the risk of a child being hospitalized due to flu.”

This season, the AAP recommends that pediatricians offer the injectable form of the vaccine to all children 6 months and older as soon as it becomes available, preferably by the end of October. The AAP recommends the injectable flu vaccine as the primary choice for children because it has provided the most consistent protection against all strains of the flu virus in recent years.

The AAP and CDC also support the use of the nasal spray vaccine – or live attenuated influenza vaccine (LAIV4) – for the 2018-2019 season with the aim of adequate vaccination coverage and optimal protection in children of all ages.

Since the nasal spray did not work as well against influenza A/H1N1 strain during the 2013-2014 and 2015-2016 flu seasons, it was not recommended in the U.S. for the past two flu seasons. Vaccine effectiveness can vary from one flu season to the next.  The effectiveness of the latest nasal spray vaccine for this upcoming season is more of an unknown against the influenza A/H1N1 strain.

Therefore, AAP recommends the flu shot as the first choice for children. The nasal spray vaccine may be used this year for children who would not otherwise receive the flu shot, as long as they are 2 years of age or older and healthy without an underlying medical condition. For instance, if a child refuses the flu shot, or if the physician’s office runs out of the injected vaccine, the nasal spray would be appropriate.

The AAP recommendations also include:

  • The number of doses of influenza vaccine depends on a child’s age and vaccine history. Children 6 months through 8 years of age need two doses when it is the first time they are being vaccinated against influenza. Children 9 years of age and older require only one dose, regardless of prior vaccination history.
  • Children with egg allergy can receive the influenza vaccine with no additional precautions than those considered for any vaccine.
  • Pregnant women may receive injected influenza vaccine at any time during pregnancy.
  • All healthcare personnel should receive an annual seasonal influenza vaccine, a crucial step in preventing influenza.
  • Antiviral medications are important in the treatment and control of influenza, but they are not a substitute for vaccination.

The influenza vaccine is given by injection into the muscle and is inactivated, meaning it does not contain a live flu virus and cannot cause the flu.

The effectiveness of the flu vaccine varies and is affected by factors such as the child’s age, health status, vaccination history and the strain of influenza circulating in a community,” said Henry Bernstein, MD, MHCM, FAAP, a member of the CDC Advisory Committee on Immunization Practices and an Ex-Officio member of the AAP Committee on Infectious Diseases. “We urge parents to talk with their pediatricians now to avoid any delay in getting their children vaccinated.”
