If you test positive for COVID-19, you should isolate from others. (https://www.coronavirus.in.gov/files/20_Family%20isolation_COVID-19_8-10-20.pdf) as recommended by the CDC and Indiana Department of Health. Clinical trials have shown that people who get vaccinated but still get COVID-19 have less severe symptoms.
