Failed attempts to quit Combustible Cigarettes and e-Cigarettes among US adolescents.

Introduction:
This text provides an analysis of the failure rates of quitting smoking and vaping among adolescents in the United States. It also examines the impact of e-cigarettes on unsuccessful nicotine quit attempts among adolescents. The study was conducted using data from the Monitoring the Future study between 1997 and 2020. The text also includes a separate study on the association between homologous and heterologous vaccine boosters and COVID-19 incidence and severity in Singapore.

Key Points:

* The study found that the percentage of adolescents who reported an unsuccessful cigarette quit attempt declined between 1997 and 2020.
* however, in 2020, the prevalence of unsuccessful quit attempts among adolescents who had used either e-cigarettes or cigarettes was higher than the prevalence of unsuccessful cigarette quit attempts in each of the previous 13 years.
* Limitations of the study include the absence of high school dropouts, reliance on self-reported data, only one year of information on e-cigarette quit attempts, and no analysis of quit attempts among users of low-prevalence tobacco products.
* The contribution of e-cigarettes to unsuccessful nicotine quit attempts among adolescents is substantial and warrants consideration as the US formulates policies to regulate e-cigarettes.
* The study on COVID-19 vaccine boosters in Singapore found that booster injections were associated with lower incidence and severity of SaRS-CoV-2 infections compared to non-booster groups.
* The study included 703,209 eligible individuals, with 576,132 receiving boosters.
* The incidence rate ratios of confirmed and severe infections were significantly lower for both homologous and heterologous boosted individuals compared to non-boosted individuals.
* The study did not include a control group of unvaccinated individuals, and data analysis was carried out using Stata version 17.0.

Main Message:
The study highlights the significant contribution of e-cigarettes to unsuccessful nicotine quit attempts among adolescents and the need for policymakers to consider this as they regulate e-cigarettes. The study also underscores the association between COVID-19 vaccine boosters and lower incidence and severity of SaRS-CoV-2 infections in Singapore. The findings of both studies have important implications for public health policy and underscore the need for continued research and analysis in these areas.
