The United States Food and Drug Administration (FDA) recently published a document from the pharmaceutical company Pfizer that reports on adverse effects after vaccination and, in turn, reaffirms that it is safe to continue with the application of this vaccine against covid.

The document covers the first three months since vaccination began and includes adverse events that have occurred in people around the world.
As a result of this, various advertisements on the Internet began to erroneously associate the Pfizer vaccine, of which more than one billion doses have been administered worldwide, as the cause of these adverse effects.

Many of the social media posts even claim that the reason the FDA document was withheld from the public is because the vaccine is not safe.
Also, in a press release, Robert F. Kennedy Jr.’s anti-vaccine organization, Children’s Health Defense, stated that Pfizer’s COVID vaccines “should be ended immediately.”
In addition to this, John Campbell, a nurse educator from the United Kingdom, uploaded a video to YouTube in which he questioned the document, and it obtained more than 1.5 million views in just three days. “Why weren’t we informed of these at the time? Because if we had been aware of them at the time, we might have had an index of suspicion and be on the lookout for them,” Campbell said in the video.
Nevertheless, the Pfizer document is an analysis of adverse eventsor health problems reported after vaccination, not directly causally related to the pharmaceutical company’s vaccine.

And while serious side effects can occur after receiving the vaccine, these are rare and most people experience temporary, non-dangerous symptoms as a sign of the body’s immune response.
In fact, the registration and monitoring of these adverse effects are used by the companies and the respective regulatory entities to identify possible risks, that have not been possible to detect in clinical trials.
Although at first glance the figures are worrying, 42,086 notifications of adverse events and 1,223 deaths until February 2021, it is important to understand that “an adverse event can be a true adverse reaction, also known as a secondary effect, that is related to the vaccine, or an event that occurred by chance after vaccination ”, explain the Centers for Disease Control and Prevention (CDC in English).
