At the Advisory Committee on Immunization Practices' June 2020 meeting, the agenda included discussions of the meningococcal vaccine, influenza vaccine, and coronavirus disease 2019 (COVID- 19).
The Advisory Committee on Immunization Practices (ACIP) is a branch of the CDC that comprises medical and public health experts who develop recommendations related to use of vaccines.1 The committee has 15 voting members: 14 experts from the fields of vaccinology, immunology, pediatrics, internal medicine, virology, public health, and other related fields, and 1 member who represents consumers with consideration to the social and community aspects of vaccination.2
The ACIP typically meets 3 times a year, in February, June, and October, and meetings are open to the public.3 ACIP meetings traditionally have been held at the CDC headquarters in Atlanta, Georgia, but the June 2020 meeting was the first to be held virtually.3 During the February 2020 meeting, the ACIP discussed updated recommendations for the anthrax vaccine, as well as the diphtheria, tetanus, and pertussis vaccines (DTaP/Tdap/Td) [see “2020 Anthrax and DTaP/ Tdap/Td Vaccine Updates” on page 9]. At the June 2020 meeting, the agenda included discussions of the meningococcal vaccine, influenza vaccine, and coronavirus disease 2019 (COVID- 19).4 The recommendations made during this meeting are discussed next.
MENINGOCOCCAL DISEASE VACCINE
The June 2020 ACIP meeting began with a discussion of the public burden of meningococcal disease. Invasive meningococcal disease is devastating worldwide, in large part because it can take a person’s life within 24 to 48 hours of infection, and it has a fatality rate of 8% to 15%, even with treatment.5 Additionally, 1 out of 5 infections result in limb amputation, deafness, or brain damage.6
MenACWY vaccines cover meningococcal serogroups A, C, W, and Y.7 Since the vaccines were introduced, invasive meningococcal disease caused by these serogroups covered by the vaccine has declined more than 90% among adolescents.7 The first MenACWY meningococcal conjugate vaccine, Menactra (Sanofi Pasteur), was introduced in 2005.8 Menactra was followed by Menveo (GlaxoSmithKline) in 2010. In April 2020, a new vaccine, MenQuadfi (Sanofi Pasteur), was approved by the FDA.9 MenQuadfi is approved for use in a broader age range (ages 2 years and older) than Menactra or Menveo, which are indicated up to age 55 (9 months to 55 years, and 2 months to 55 years, respectively).8,10,11
During the June 2020 meeting, the ACIP approved a new meningococcal vaccination resolution (6/20-1) for the Vaccines For Children (VFC) program, a federally funded program that provides free vaccines to children, including all the meningococcal conjugate vaccines that prevent meningococcal disease from serogroups A, C, W, and Y.12 ACIP-recommended vaccine schedules, intervals, dosages, contraindications, and precautions remain the same, and no changes were made to the VFC recommendations for serogroup B meningococcal vaccines.13
INFLUENZA VACCINE
The ACIP influenza work group estimated that between October 1, 2019, and April 4, 2020, there were more than 39 million influenza cases in the United States, which led to more than 18 million influenza-related medical visits, more than 410,000 hospitalizations, and as many as 62,000 deaths.14 As of August 10, 2020, estimated vaccine effectiveness for any type influenza across all age groups was 39%.15
Looking to the 2020-2021 influenza season, the ACIP followed the recommendations for the upcoming season’s vaccine components from the World Health Organization.16 These include A/H1N1pdm09-like viruses, A/H3N2-like viruses, and B/Victoria lineage-like viruses for trivalent vaccines with the addition of B/Yamagata lineage-like viruses for quadrivalent vaccines.16,17 The ACIP carried over its core recommendation that everyone aged 6 months and older without contraindications should receive an annual influenza vaccination.18 In addition, 2 recently licensed vaccines, Fluzone High-Dose Quadrivalent (Sanofi Pasteur) and Fluad Quadrivalent (Seqirus), were added to the list of available vaccines for the 2020-2021 influenza season.19,20 Both vaccines are licensed for patients ages 65 years and over.21,22 Fluzone High-Dose Quadrivalent will replace Fluzone High- Dose (trivalent).16,23
COVID-19 VACCINE
As of August 11, 2020, there have been more than 5 million cases of COVID-19 diagnosed in the United States, of which 162,407 occurred in health care providers.24
The ACIP announced that a new work group had been organized in April 2020 to create evidence-based approaches to advise on COVID-19-related vaccination policies for discussion, deliberation, and vote by the ACIP.25 The work group is reviewing COVID-19 epidemiology, characteristics of vaccine candidates that are in development, and evidence-based vaccine recommendations, ethics, and equity frameworks.
According to the ACIP, work group goals include26:
However, the work group intends to adjust and refine this prioritization plan as new COVID-19 data and vaccine information become available.
Ordinarily, the next meeting of the ACIP would be held in October 2020; however, the ACIP recently announced 2 additional virtual meetings, which will be held August 26, 2020, and September 22, 2020. The live webcast meetings are open to anyone who wants to watch; registration is not required.3
CONCLUSIONS
The June 2020 ACIP meeting included customary discussions of the annual influenza vaccine and availability of a new meningococcal vaccine, but the meeting was unprecedented in its virtual delivery method and discussion of a vaccine for a global pandemic. In the coming months, the proposed priority groups will likely evolve as the possibility of a vaccine for COVID-19 draws closer.
