PHARMACEUTICAL giants Pfizer sent the stock market soaring in November 2020 when they announced that clinical trial date showed the ‘efficacy’ of its Covid 19 vaccine was more than 90 per cent – a figure soon raised to 95.

Moderna responded by claiming 94 per cent ‘efficacy’ for its vaccine.

So far, so good. The problem was nobody asked what they meant by ‘efficacy’.

Without presuming to speak for the population of the planet, you can reasonably guess that most folk came to the conclusion the vaccine radically reduced hospitalisation and deaths by more than nine in ten.

Information that is freely available about the clinical trials show this could not possibly be the case because hospitalization and death wasn’t even included in the trials!

In an article published by the Mises Institute, Dr Gilbert Berdine, associate professor of medicine at Texas Tech University Health Sciences Centre, explains: ‘The Pfizer study had 43,538 participants and was analysed after 164 cases.

‘So, roughly 150 out of 21,750 participants (less than 0.7 per cent) became PCR positive in the control group and about one-tenth that number in the vaccine group became positive.

‘The Modern trial had 30,000 participants. There were 95 ‘cases’ in the 15,000 control participants (about 0.6 per cent) and five in the 15,000 vaccine participants.

‘The ‘efficacy’ figures quoted in these announcements are odds ratios.

‘When the risks of an event are small, odds ratios can be misleading about absolute risk. A more meaningful measure of efficacy would be the number needed to prevent hospitalization or one death.

‘These figures are not available.’

His comments are based on the revelation that a case of Covid 19 in the trial was defined by a positive PCR test and not an illness, let alone one leading to hospitalization or death.

Do you trust such a company?
