The COVID-19 pandemic, caused by the SARS-CoV-2 virus, had strong impacts that go beyond the health aspect. This research was carried out with COVID-19 data from Arapongas - PR, Brazil. Between March 2020 and June 2023, 41305 cases and 644 deaths by COVID-19 were recorded. In the first half of 2021, the lethality rate for the period was 2.91%, and in the first half of 2023, the rate was 0.31%. The reduction in the lethality rate coincided with the increase in vaccination rates, since, by June 2023, 93.17% of the population had received at least one dose of the vaccine and 84.73% the second dose or single dose. If the lethality rate had remained at the level recorded until the first half of 2021, the city would have recorded 426 more deaths from COVID-19, reaching 1070 deaths, an increase of 66.15%. Despite hesitancy fueled by misinformation and social media, the vaccination campaign (COVID-19) was highly effective. Of the 644 deaths related to COVID-19, 73.9% were unvaccinated. No deaths were recorded among individuals under 60 years of age who received the fourth dose, 2nd booster or bivalent vaccine, and for individuals aged 60 or over, five deaths were recorded among those who received the fourth dose or 2nd booster, and no deaths for those who received the bivalent vaccine. The conclusions affirm the potential of vaccines to save lives and the need for ongoing public health initiatives to prevent and treat diseases, carry out vaccination campaigns and combat fake news.
