Study finds a covid vaccine that could last for years

A new St. Louis area study has shown at least one COVID vaccine could provide immunity for years. 

The news comes nearly seven months after the COVID-19 vaccine was first administered in the St. Louis area.    

Researchers at Washington University said most people who have received the Pfizer vaccine can rest assured knowing they have protection against the original strain of COVID-19 that could possibly last for years.  

The study tracked over 40 people for a five-month timeframe after they received the Pfizer vaccine.
