Comment by tonytran2015: Immunity from the first infection and from any vaccine should be questioned.
Five sailors on the ship docked in Guam after a
COVID-19 outbreak have gotten the virus for the second time and have
been taken off the ship.
The resurgence of the
virus in the five sailors on the USS Theodore Roosevelt underscores the
unpredictable behaviour of the highly contagious virus and raises
questions about immunity.
All five sailors had
previously tested positive and had gone through at least two weeks of
isolation. As part of the process, they all had to test negative twice
in a row, with the tests separated by at least a day or two before they
were allowed to go back to the ship.
