Excerpt:

Scientists from the Cleveland Clinic, USA, have recently evaluated the effectiveness of coronavirus disease 2019 COVID-19) vaccination among individuals with or without a history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

The study findings reveal that individuals with previous SARS-CoV-2 infection do not get additional benefits from vaccination, indicating that COVID-19 vaccines should be prioritized to individuals without prior infection. The study is currently available on the medRxiv* preprint server.

Intelligence on Sick Staff at Wuhan Lab Fuels Debate on Covid-19 Origin

Excerpt:

Three researchers from China’s Wuhan Institute of Virology became sick enough in November 2019 that they sought hospital care, according to a previously undisclosed U.S. intelligence report that could add weight to growing calls for a fuller probe of whether the Covid-19 virus may have escaped from the laboratory.

The details of the reporting go beyond a State Department fact sheet, issued during the final days of the Trump administration, which said that several researchers at the lab, a center for the study of coronaviruses and other pathogens, became sick in autumn 2019 “with symptoms consistent with both Covid-19 and common seasonal illness.”

….

China’s National Health Commission and the WIV didn’t respond to requests for comment. Shi Zhengli, the top bat coronavirus expert at WIV, has said the virus didn’t leak from her laboratories. She told the WHO-led team that traveled to Wuhan earlier this year to investigate the origins of the virus that all staff had tested negative for Covid-19 antibodies and there had been no turnover of staff on the coronavirus team.

Marion Koopmans, a Dutch virologist on that team told NBC News in March that some WIV staff did fall sick in the autumn of 2019, but she attributed that to regular, seasonal sickness.

…..

It isn’t unusual for people in China to go straight to the hospital when they fall sick, either because they get better care there or lack access to a general practitioner. Covid-19 and the flu, while very different illnesses, share some of the same symptoms, such as fever, aches and a cough. Still, it could be significant if members of the same team working with coronaviruses went to hospital with similar symptoms shortly before the pandemic was first identified.
