From the actual commentary ( https://www.nejm.org/doi/full/10.1056/NEJMsb2506929 ):

Over the past two seasons, uptake of the annual Covid-19 booster has been poor, according to the Centers for Disease Control and Prevention (CDC). Less than 25% of Americans received boosters each year, ranging from less than 10% of children younger than 12 years of age in the 2024–2025 season to 50% of adults over 75 years old.4 Even health care workers remain hesitant, with less than one third participating in the 2023–2024 fall booster program.5 There may even be a ripple effect: public trust in vaccination in general has declined,6 resulting in a reluctance to vaccinate that is affecting even vital immunization programs such as that for measles–mumps–rubella (MMR) vaccination, which has been clearly established as safe and highly effective. In recent years, reduced MMR vaccination rates have been a growing concern and have contributed to serious illness and deaths from measles. Against this context, the Food and Drug Administration (FDA) seeks to provide guidance and foster evidence generation.

Absolutely fucking bullshit spin, trying to redefine “poor” and scapegoat the vaccines themselves for the anti-vaxxers’ disinformation.
