Cynthia Posted December 25, 2021 Share Posted December 25, 2021 With all the vaxed people coming down with covid now, when is natural immunity going to play a part of this, when can we get on a cruise ship?? Now scientist are talking about a study they have done natural immunity last a very long time as long as 17 years, t cells lay dormant in your blood so if you contract the virus again they step in to fight it. 1 Quote Link to comment Share on other sites More sharing options...
