A man named Carey Washington was very excited to receive both of his vaccine doses by February 4th, but just a month later, things took a turn for the worst. He became positive with Covid-19 and fought against the virus for two weeks in the hospital before his lungs were destroyed. The unfortunate truth is that the vaccine is not a perfect immunization, and people will still need to be vigilant even after receiving the vaccine. Covid-19 cases and deaths after receiving the vaccine are troublesome, but researchers are working to see why these cases are occurring.
