ACIP: US changes to vaccine guidance and recommendations

The American Advisory Committee on Immunization Practices (ACIP) met recently, voting to change MMRV and COVID-19 vaccine guidelines and recommendations, and postponing a vote on proposed changes to hepatitis B vaccination.

The combination measles, mumps, rubella and varicella vaccine (MMRV) is no longer recommended in the US for children under 4 years of age. The COVID-19 vaccine is no longer recommended for all adults in the US; recommendations are now subject to a ‘shared decision-making’ process whereby individuals are advised to weigh up risks and benefits with a healthcare professional.

Via our social media platforms, MVEC has published a shortform explainer (@mvecau on Instagram) on ACIP’s MMRV change and why it shouldn’t impact confidence in Australia’s immunisation program. 

Materials from the 18 to 19 September meeting are not yet fully accessible for all audiences.  

The following articles from US-based publications offer more context on the ACIP meeting:

NEJM: Clesrovimab for prevention of RSV disease in healthy infants

A recent trial has shown that a single dose of the monoclonal antibody clesrovimab reduced the incidence of RSV-associated lower respiratory infection and RSV-associated hospitalisation in healthy preterm and full-term infants. 

Clesrovimab demonstrated 60% efficacy in reducing medically attended RSV-associated lower respiratory infection and 84% efficacy in reducing RSV-associated hospitalisation. The adverse-event profile of clesrovimab was similar to that of placebo. The authors note that rare serious adverse events may not be detected in a trial of this size (3632 infants).
