WHO official investigating pandemic warns world to ‘manage expectations’ as team leaves quarantine


Now in Wuhan, team of 13

Dutch virologist, Marion Koopmans

I think we really have to manage expectations,

if you look at some of the earlier quests for the origins of outbreaks,

they have taken years to complete.

Wuhan lab staff, first victims of coronavirus?


Chinese virology laboratory, sick, Covid-like illness in autumn 2019

US, State Department, 16th January

undisclosed information

has reason to believe that several researchers inside the WIV became sick in autumn 2019,

before the first identified case,

with symptoms consistent with both Covid-19 and common seasonal illnesses

Lab had been carrying out research on a bat coronavirus

The CCP has prevented independent journalists, investigators, and global health authorities from interviewing researchers at the WIV

AstraZeneca vaccine quasi-ineffective in over 65s



Vaccine commission, STIKO

Oxford AstraZeneca, only to people aged 64 and under

There is currently insufficient data to assess the efficacy of the vaccine for persons aged 65 years and older

Lancet, 18th November


In participants who received two doses of vaccine,

median anti-spike SARS-CoV-2 IgG responses 28 days after the boost dose were similar across the three age cohorts

18–55 years (n = 39)

56–69 years (n=26)

more than 70 years (n=47)

By 14 days after the boost dose, 208 (more than 99%) of 209 boosted participants had neutralising antibody responses.

T-cell responses peaked at day 14 after a single standard dose of ChAdOx1 nCoV-19

Professor John Bell, Oxford University vaccine team

I’m not sure where he got that from

Other studies proved elderly people responded just as well in other age groups

there’s really persuasive evidence that this is a protective vaccine in those populations
