Yes that I knew about.
Apparently CNBC had an article, today, about a US ship which had reinfected people on it. My son read it. He said the entire article read like "see people can be reinfected". The very last paragraph said that the on board medical team believed that their tests were not sensitive enough to show that the virus had not fully left the system and that, under constant viral load, the virus could emerge again.
I haven't seen it so have to take it second hand. But he was unimpressed.
I think that there is pretty clear evidence that under the right circumstances Any virus can infect anyone again. What I don't see is solid evidence that this virus is special and does not follow the standard virology path and immunity path. I believe that those who constantly talk down a vaccine have to prove just exactly why this virus is so different from, let us say, SARS, MERS or Swine flu. Especially given the lack of solid evidence, backed up by many cases, to prove the point
Other than that, I guess we all just get on with it. Personally I'd like the Antibody tests for both me and Mrs S. In the case where I might have been infected and didn't know it, I would quite happily be a guinea pig for the "immunity doesn't exist" test.....
