People who recover from COVID-19 sometimes later test positive for SARS-CoV-2, suggesting their immune systems could not ward off a second attack by the coronavirus or that they have a lingering infection. A study now hints at a different explanation in which the virus hides in an unexpected place. The work, only reported in a preprint, suggests the pandemic pathogen takes a page from HIV and other retroviruses and integrates its genetic code—but, importantly, just parts of it—into people’s chromosomes. The phenomenon, if true and frequent, could have profound implications that range from false signals of active infection to misleading results from COVID-19 treatment studies.
The current study only showed this integration in a lab dish, although it also cites published sequence data from humans infected with SARS-CoV-2 that suggest it has happened. The authors emphasize that their results don’t imply that SARS-CoV-2 establishes permanent genetic residence in human cells to keep pumping out new copies, as HIV does.

輝瑞疫苗自己的確把“injection site pain”算作副作用的。問題是人們在討論副作用時並不首先做具體的定義，而是根據各自的立場去發揮，所以爭論不可開交，如同雞同鴨講。任何注射的疫苗，注射局部疼痛是一定的，從這個意義上來說該疫苗100%有副作用，但如果該疫苗其它類型的比較嚴重一點的副作用發生率很低，它仍然很好。要看嚴重的、一旦發生就需要醫療處理的副作用發生的概率。
