- Smokers and snus users had a notable decrease in vaccine uptake, emphasizing a gap in vaccination efforts among tobacco users.
- Targeting smokers and snus users in public health campaigns could effectively improve COVID-19 vaccination rates in these populations.
The association between tobacco use and COVID-19 is controversial. During the early course of the pandemic, limited testing prevented studying a wide spectrum of clinical manifestations.

We examined whether the prevalence of tobacco and nicotine use and nicotine-replacement therapy (NRT) changed during the COVID-19 pandemic and whether changes differed by sociodemographic groups.
Methods: Repeated cross-sectional study of three national surveys in Finland (2018, 2019 and 2020; n = 58 526 adults aged 20 and over).
