Vaccine efficacy and duration of protection

Does vaccination prevent long COVID?

Vaccines may reduce the risk of long COVID by lowering the chances of contracting COVID-19 in the first place. Researchers in Israel report that vaccination with at least two doses of a COVID-19 vaccine was associated with a substantial decrease in the most common post-acute COVID-19 symptoms [^1].
