Infertility is not a risk with Covid-19 vaccines in children

A study published by the Kaiser Family Foundation last week found that 66% of parents of 5- to 11-year-olds were concerned that vaccines could have a negative impact on children’s fertility later on.

Doctors and public health officials are united in reassuring parents that this is not a concern.

“Unsubstantiated allegations linking COVID-19 vaccines to infertility have been scientifically refuted,” the American Academy of Pediatrics, which represents physicians specializing in treating children, said in a statement on its website.

“There is no evidence that the vaccine can lead to loss of fertility. Although fertility was not specifically studied in clinical trials with the vaccine, no loss of fertility has been reported among trial participants or among the millions who have received the vaccines since their authorization, and there was no evidence of infertility in animal experiments, “it adds.

Pediatricians say some parents are eager to vaccinate their children, while others ask questions as doses of child-sized Covid-19 vaccine are sent out

“Similarly, there is no evidence that the COVID-19 vaccine affects puberty.”

The American College of Obstetricians and Gynecologists, which represents the doctors who treat pregnant women, give birth to babies, treat infertility and help women prepare for pregnancy, also encourages women to be vaccinated against Covid-19. “First medical organizations have repeatedly confirmed that COVID-19 vaccines have no effect on fertility,” it says.
The same goes for male fertility, say the U.S. Centers for Disease Control and Prevention.

Distribution of vaccines is expected to start in children aged 5 to 11 as early as this week. The U.S. Food and Drug Administration last Friday issued an emergency use permit for Pfizer’s vaccine in this younger age group, and vaccine advisers to the CDC will meet to discuss whether to recommend use for these young children on Tuesday.

FDA vaccine advisors are notoriously independent and are not afraid to make unpopular opinions at their meetings. Last week, several members of the FDA’s advisory committee on vaccines and related biological products expressed concern about whether it was worth vaccinating this entire age group at this time.

Not a single one raised a question of effects on fertility. This is because there is no scientific reason to believe that a vaccine can affect a child’s development at puberty or their future fertility, doctors have repeatedly said. And the committee later voted 17-0, with one abstention, to recommend emergency use of the vaccine in the age group of 5 to 11 years.

Dr. Paul Offit, one of the FDA’s vaccine advisors, a pediatrician and head of the Vaccine Education Center at the Children’s Hospital of Philadelphia, explains in a video where one of the myths came from.

“This false notion was born out of this letter, which was actually written to the European Medicines Agency, which is like the European equivalent of the Food and Drug Administration, and claimed that there was a similarity between the SARS-CoV-2 peak protein, which is it “you make an antibody response when you get these vaccines, and a protein that sits on the surface of placental cells called syncytin-1,” he says.

“So the idea was that if you make an antibody response to that nail protein from coronavirus, you are also inadvertently making an antibody response to that syncytin-1 protein on the surface of placental cells, which would then affect fertility.” he adds.

“First of all, it was not right. The two proteins are very different. It’s like saying you and I both have the same social security number because they both contain the number five. So that was wrong to begin with, says Offit in the video.

“If it affected fertility, if natural infection affected fertility, then birth rates should have dropped, but that’s not what happened. Birth rates have actually risen slightly. So there’s two pieces of evidence arguing against this vaccine or natural infection in every sense. affecting fertility. “

Dr. Peter Marks, who heads the FDA’s vaccine department, addressed the fears at a news conference Friday.

“These vaccines have been evaluated in a number of studies before coming to the clinic, and they have now been given to many, many millions of people. There is no evidence that there is a negative effect on the fertility of these vaccines, and there is no reason to suspect that an mRNA vaccine would have this, “Marks said.

Both Pfizer’s vaccine and Moderna’s vaccine are called mRNA vaccines. They use genetic material called messenger RNA or mRNA to instruct the body’s own cells to make a small piece of the coronavirus tip protein, which in turn trains the body to recognize it and attack it. Some scientists have described mRNA as being a Snapchat message – it delivers instructions to cells and then disappears.

“The way these vaccines work when they enter the cell, the cell makes the protein for a short period of time – that is, on the surface of the cell. The body makes an immune response. And the original vaccine, the mRNA component, is broken down. It is “Not incorporated into a person’s genetic material. There’s no way that can happen,” Marks said.

“So these vaccines are the ones that we are quite comfortable with, would be reasonable to use for children. I would not hesitate to give them, if I had had still younger children in this age group, (I) would not hesitate a second to give my child one of these vaccines. “

People who worry that vaccines can cause infertility in their children are not alone. During polio vaccination campaigns in Nigeria in the 1990s and early 2000s, many communities resisted due to rumors that the vaccine was in fact a covert attempt to sterilize people in order to reduce the population.

There was also fear of the human papillomavirus or HPV vaccine and the risk of infertility in the United States – fears driven by rumors that the vaccine somehow caused a condition called primary ovarian failure. Several major studies have shown that this is not true.
