Controversy over poor Pfizer clinical trials… “need to investigate side effects”

Love

A global medical journal has announced that Pfizer’s COVID-19 vaccine clinical trials have not been rigorously conducted. The preventive effect is exaggerated, and the side effects in particular have not been sufficiently investigated.

Cho Dong-chan, a medical professional reporter, covered the story.

It is the most prestigious medical journal in the UK.

They said that they had received statements, transcripts and emails from one former and two current Pfizer clinical trials and investigated them.

First, he pointed out that the 94% preventive effectiveness of Pfizer vaccines derived from clinical trials may not be accurate.

The researchers and participants should not know who gets the real vaccine and who gets the fake vaccine, because this was not followed.

In this case, prejudice may act and the effect may be exaggerated.

The U.S. Food and Drug Administration (FDA) also argued for improper action.

A researcher reported an error in the clinical trial procedure to the US FDA, but it was not accepted and he was fired from the company.

It was also noted that there was a lack of investigation of serious side effects.

Pfizer said it regrets any unilateral claims aimed at undermining vaccine confidence, but said it is investigating vaccine concerns thoroughly.

An official from the Korean Vaccine Society analyzed that although some regulations were violated, it would not have had a significant impact on the preventive effect of the vaccine.

This is because it has been proven effective in many countries other than the United States.

However, he says that the side effects controversy should be taken into account.

Although the side effects of menstrual irregularities are present in quite a few people, the fact that no investigation was conducted at the time of the clinical trial means that they were passive in the investigation of side effects.

The rare but severe side effects, such as myocarditis and pericarditis, were reported less than six months after approval because the study period was insufficient.

Rather than relying solely on pharmaceutical company data, we also need to revise our preventive measures and compensation system by investigating vaccine side effects on our own.
