Here are the actual figures from the report rather than the summary: Vaccine effectiveness against symptomatic infection During a mean (range) follow-up of 116 (15-280) days, a symptomatic infection was confirmed in a total of 27,918 individuals, of which 6,147 were vaccinated individuals...

We have to be careful with this type of information. Your first source is from a very small population (246 individuals) and contains a major flaw (which the report writers acknowledge) in that they only selected people who had been tested rather than a random population sample. "persons who...

Except that may not be true according to the UK Health Security Agency. They observe: (iii) recent observations from UK Health Security Agency (UKHSA) surveillance data that N antibody levels appear to be lower in individuals who acquire infection following 2 doses of vaccination. What this...

I'm not saying you are wrong but its a lot more complicated than that. A very large UK study in the Lancet published on 29/10/2021 showed the following: There is no statistically significant difference in the likelihood of you catching Covid from someone who enters your household who has Covid...

This is the current reality from a UK critical care doctor working in a UK HCID (high consequence infectious diseases) unit. Without talking specifically about my unit, the critically ill patients across the UK are in a broad age mix. There are a smaller number of younger patients (30s to 40s)...

There is a difference between mortality rate and case mortality rate. They are two different things. The 5000 other active cases have no known outcome. How can they possibly be included in any mortality / case mortality rate?

Happy to be corrected by those with more knowledge. The latest figures I can see are for Italy are. Known deaths: 233 Known recoveries: 589 Total population with known outcome:822 Known current case mortality rate is 233/822 x 100 = 28.3% For those quoting 4% I believe that figure includes...

The above is why this is a big issue and the fact that what happened / is happening in China was probably not the whole picture. Lombardy, Italy’s welfare minister: "Every day we get 200 new people to the ER in critical conditions, which means every day we need to find 200 more hospital beds...

Yes the % death rate is relatively good news here and I suspect is the most accurate we have at this time based on the amount of testing the Koreans have done to identify cases. However I suspect they are identifying cases early and there is a large lag in their death rate. So of the 5624 cases...

60% of transmission of virus transmission in South Korea is now community spread meaning the virus is endemic in that country. South Korea has performed over 100,000 tests, has text alerts to alert local populations of infected individuals and the places they visited, has a mask wearing and...

A vaccine is a minimum 12 months away and then you have to add in the manufacturing capacity to produce the vaccine. Also be aware that attempts to produce a SARS vaccine (a coronavirus relative) were not ultimately successful because the immunity produced by the vaccine (given to mice) produced...

Singapore temperatures are in the 30's at the moment.

Yes I agree, it does appear to be an issue with a particular kit. It also appears that in certain individuals and under certain conditions the virus sits deep in the lungs and not in the nasal or throat passages where swabs for testing are taken from. So x-rays would help in these cases (if the...

Incubation 24 days. A study released on Sunday by Chinese epidemiologist Zhong Nanshan, who discovered the SARS virus in 2003, revealed that COVID-19's incubation period ranges up to 24 days. https://www.medrxiv.org/content/10.1101/2020.02.06.20020974v1

Covid-19 is probably being spread through the air. The incubation period of Covid-19 is probably up to 24 days. Covid-19 can probably be spread asymptomatically. Covid-19 tests are probably producing false negative results. There is some evidence you can be reinfected after you have had it...

This is what the Singapore PM said today and is almost certainly where China is now and where we are headed. This would also explain the drop in Chinese numbers if they are following this strategy. They are only counting severe cases now. Straight from the Prime Minster's Office "If the...
