COVID-19

Alain Fisher, when will we know if vaccines have long-term side effects?

He is not a “revolutionary and not a conspirator.” No, 61-year-old Eric “just doubts like so many.” Since the advent of the Covid vaccines, this top electrician on television and on the series has been surprised: quick approval, lack of prospects, fear of future impact on his health. What if there were consequences that we didn’t know about? “For now, I’ll still find time before getting vaccinated, maybe this winter or next year,” says this former high-level gym, which relies on “good health” to fight the virus when infected.

To date, the data from the National Agency for the Safety of Medicines is quite encouraging, as 74% of reported side effects are not serious, such as flu symptoms, and there have been no recent signals of four products being introduced in France. But now, rare cases of blood clots with AstraZeneca are fueling mistrust. Currently, 44 atypical thrombosis have been reported, including 11 fatal ones. The link between the Pfizer vaccine and some cases of myocarditis, an inflammation of the heart muscle, often benign, is being studied and cases of high blood pressure are being confirmed, including for Moderna.

If adherence to vaccines is progressing in France and 50% of adults have already received their first dose, questions about long-term side effects still hold back skeptics. Dear Alain Fischer, you made a cautionary note with your slogan when you were appointed the government’s “mister vaccine” in December. So, can we detect the long-term side effects of the Covid vaccination? And if so, when will we know? In a few months, a year, ten years? Are there “delayed” effects with other vaccines? Do you finally understand that the population may be worried about it?

Parisien-Today readers in France are eagerly awaiting your response.

Alain Fischer’s answer: “Covid vaccination does not cause long-term complications.”

Alain Fischer first replies to the chief electrician that at his age, if he is infected with Covid, the risk of hospitalization is about 5%, and of death – 1%. However, “vaccination against the virus makes it possible to prevent this infectious risk in more than 90% of cases. Thus, the benefits of vaccination clearly prevail, ”he says in the preamble.

Then, speaking of long-term side effects, Alain Fischer reassures her based on past experience. “In the history of vaccination, rare and very rare serious side effects that were observed for days or weeks after vaccination, there is no concept of long-term complications. Vaccination for the type of vaccine used for Sars-COV-2 ”.

If so, they are already being observed. Moreover, 74% of them are not serious. As for the messenger RNA vaccines, that is, Pfizer and Moderna, the professor recalls that “the injected RNA disappears after three days and does not interact with the cellular genome. It also does not induce an aberrant immune response. ” Also, it is probably less well known, but “RNA vaccines have been used for a long time in the cancer field with no adverse effects in the medium or long term,” he writes.

With regard to its competitors, the adenovirus vaccines AstraZeneca and Janssen, “we can say that the genetic material is not conserved and that vaccines of this type were already used several years ago to treat Ebola virus fever. adverse effects in the medium or long term ”. Conclusion: don’t worry. “In general, both the benefits of vaccines and their safety are such that they reassure everyone who has similar questions. “
