Evaluation of Self-reported Cannabis Vaping among US Youth and Young adults Who Use e-Cigarettes.

Introduction:
This text provides an analysis of the decline in vaccination rates and reduction in the proportion of children up-to-date with vaccinations across the US during the COVID-19 pandemic. The study focuses on younger age groups, particularly children aged 7 months, and the impact of the expanded opening of primary care on making up for missed vaccines. The text also discusses the challenges of catch-up vaccination and the importance of timely administration of vaccines during the pandemic.

Key Points:

* The COVID-19 pandemic has led to a decline in vaccination rates and reduction in the proportion of children up-to-date with vaccinations across the US.
* Younger age groups, particularly children aged 7 months, were affected the most.
* The packed immunization schedule of children in the first months of life considerably affected overall adherence.
* Catch-up vaccination is not feasible for all vaccines, especially for rotavirus (RV) vaccines.
* The first dose of pentavalent RV vaccine is recommended by age 12 weeks, and the vaccination course should be completed by age 32 weeks.
* The two doses of human monovalent RV vaccines should be administered no later than ages 16 and 22 weeks, respectively.
* New evidence about the safety of late RV vaccine administration is emerging, but a catch-up vaccination schedule is currently not available in high-income settings.
* Interventions are needed to ensure timely administration of vaccines during the COVID-19 pandemic, and RV vaccinations should be identified as a specific aim.

Main Message:
The COVID-19 pandemic has had a significant impact on vaccination rates and adherence to vaccination schedules, particularly for younger age groups. It is crucial to ensure timely administration of vaccines during the pandemic, especially for RV vaccines, which require completion within a short period. New evidence about the safety of late RV vaccine administration is emerging, but a catch-up vaccination schedule is not yet available. Interventions are needed to address these challenges and ensure that children receive necessary vaccinations to prevent the increase in disease rates and risk of outbreaks.
