Corona virus | Decryption: “Pfizer Documents”, beware of this large flow of information on the Covid vaccine

Several weeks ago, blogs, tweets, or Facebook posts circulating purportedly about “Danger” A vaccine for Covid, which will come from “Pfizer documents”. If these documents already existed, they have been distorted and their context removed.

95% injection efficiency sold out, but #pfizerdocuments reveal 12% efficiency for the first 7 days and then 1%“,”So the #Pfizer documentation shows that their vaccine is not recommended for pregnant and breastfeeding women.“.

Pfizer knew its vaccines would kill“Can we read too… These are some of the countless publications that abound in English, Serbian, French, Finnish, Dutch or German on the Internet.

Where do these documents come from?

The US Drug Agency, the Food and Drug Administration, is gradually publishing tens of thousands of pages related to the authorized Pfizer / BioNTech vaccine as of the end of 2020. It has had to publish about 330,000 pages due to its restriction by court decision.More than 12,000 pagesBefore January 31, 2022 and then55,000 pages every 30 daysSince the 1st of March.

But with each batch of “Pfizer documents”, many misleading claims re-emerge, although most of them have already been refuted by many scholars around the world and have been the subject of numerous verification articles. Some are based on these documents, others are simple recycling, and are tagged with the keyword #pfizerdocuments to ensure maximum potency.

side effects

The seriousness of the vaccine is one of the collectively circulated hypotheses. In fact, many publications claim that these documents list a myriad of annoying side effects, with some netizens conjuring 8 or 9 pages of disorders and diseases.

In fact, this list isNegative events of particular importance‘This vaccine, several pharmacovigilance experts confirmed to AFP.

“3% mortality” during the trials?

Another point that fuels fake news: Some publications claim that Pfizer documents reveal that during vaccine trials, more than 1,200 people – “3%“Of the participants – he will die.

The document notes 1,223 deaths reported among vaccinated people. By correlating this number with the total number of reported side effects reported (just over 42,000), many netizens came to the conclusion “3% deathsrelated to vaccination.

As the document itself states, the data used comes in particular from reports of deceased persons submitted to Pfizer by health authorities in several countries, without a causal relationship with the vaccine. So the figure 3% cannot show the mortality rate from vaccination, which means the number of deaths attributable to vaccines in relation to the number of doses given.

“1% efficiency”?

Pfizer reported at the end of its clinical trial that its vaccine was 95% effective, meaning that among people vaccinated during the clinical trial, those who received the vaccine were less likely to develop the disease. The group that did not receive the product (but a placebo).

But many publications provide other numbers, including “1%“.

There are actually two ways to calculate a vaccine’s efficacy rate:Relative risk reduction“(95% famous)”Absolute risk reduction‘, which while statistically correct, is hard to read since it circles the Pfizer vaccine around 0.85 points. And that’s where the 1% figure, given by netizens, seems to come from.

Since the start of vaccination campaigns around the world, more than 10 billion doses of the vaccine (all brands combined) have been administered. Independent scientists and health authorities continue to emphasize that efficacy remains high and that the ratio of benefits and risks is largely favourable, even if “in the real lifeThe efficacy rate is lower than the 95% observed during the tests.

Pregnant and lactating women

Although internet publications cite “Pfizer documents”, screenshots supporting these claims come not from the company but from the British Medicines Agency (MHRA). In a note dated December 8, 2020, the start of the vaccination campaign in the United Kingdom, this body wrote that the Pfizer vaccine “Not recommended during pregnancy” And “It should not be used during breastfeeding“.

But it clarifies that these precautions are due to a lack of data at the time. And for good reason: Phase III trials of the vaccine have excluded pregnant women, which has been known from the start. As in many countries, the UK initially, as a precautionary principle, did not recommend the vaccine for pregnant and breastfeeding women.

Since then, most countries have not only authorized but recommended the vaccine for pregnant women due to the particular risks of Covid to this population (risk of preterm birth for example).
