No Signs COVID-19 Vaccine Causes Infertility

Even before the Food and Drug Administration (FDA) granted emergency use authorization in early December for the first vaccine designed to fight COVID-19, rumors were circulating online that such a vaccine could cause infertility. The buzzy idea may have made the rounds on social media, but there was no evidence backing up the claims. The rumor is simply unfounded, according to health experts worldwide.

“These new COVID-19 vaccines are an important step toward a return to normalcy within our society, and baseless claims about possible links to infertility shouldn’t stop people from getting inoculated,” says Thomas Bader, M.D., vice president of medical quality at Hackensack Meridian Health. “The FDA has determined that these new vaccines are safe and effective, based on rigorous clinical trials, and no evidence has suggested that problems with fertility is even a consideration.”

Understanding fears related to vaccines

Since the 1990s, some people who choose not to vaccinate themselves or their children – have contributed to spreading the idea that people should avoid vaccinations because they may be more harmful than helpful. But in reality, vaccines protect countless people from becoming ill. They can help prevent diseases and illnesses like polio, measles, the flu and pneumonia.

The new COVID-19 vaccines have the potential to help end the pandemic, once enough people receive their doses. People shouldn’t become “vaccine-hesitant” because of false online rumors.

Some people may be unsure about the safety of the COVID-19 vaccines because they contain a new type of technology, known as messenger RNA (mRNA). The new vaccines are the first to be released with this technology, but researchers have studied mRNA vaccines for years. This type of vaccine provides an immune response in a different way than other vaccines do, but it causes the same result, protecting you from disease. And mRNA technology does not lead to infertility.

Vaccines and fertility

Other types of vaccines also don’t impact fertility. In fact, doctors routinely recommend vaccinations to women who are trying to conceive, as well as pregnant women, because pregnant women and newborns may be more susceptible to illness.

Some research suggests that COVID-19 itself – the virus, not the vaccine – may impact sperm quality, which could contribute to problems with infertility in some people. Vaccination against COVID-19 may help to protect male fertility, although more research is needed.

What side effects to expect from a COVID-19 vaccine

It’s normal and expected to experience side effects after getting vaccinated, but infertility isn’t something to expect. The most commonly reported side effects of COVID-19 vaccines are:

• feeling tired or fatigued
• headache
• joint and/or muscle pain
• fever and/or chills
• nausea and/or vomiting
• pain at the site of the injection
• swollen lymph nodes in the arm that received the injection

Such reactions are not unique to COVID-19 vaccines; all vaccinations may cause temporary, mildly unpleasant side effects like these. When your body reacts this way, it’s a sign that the vaccine is working.

In the end, Dr. Bader says, “Choosing to protect yourself, your loved ones and your community from this harmful virus should not have any impact on your fertility status.”
