A persistent myth claims that COVID-19 vaccines impair fertility, but this has been thoroughly debunked by science. In 2025, the CDC reaffirmed that vaccines have no impact on fertility in any gender, based on extensive studies tracking reproductive health outcomes. The Mayo Clinic Health System also confirms these findings, strongly recommending vaccination for those planning families. These robust data provide reassurance: vaccines are safe, do not affect fertility, and protect the health of future parents and children.

2. COVID-19 Vaccines Do Not Alter DNA

A widespread misconception is that mRNA or viral vector COVID-19 vaccines can change your DNA. This is scientifically impossible. mRNA vaccines, like those developed for COVID-19, deliver instructions to cells to make a harmless protein, prompting an immune response. These instructions never enter the cell’s nucleus, where your DNA is stored, and are quickly broken down after use. Viral vector vaccines work in a similar way, without integrating into the genome. For more details, visit the CDC’s educational resources.

3. Microchip Myths Debunked

The idea that vaccines contain tracking microchips has been flatly dismissed by both the CDC and WHO. Such technology is not only absent from all vaccines, but also scientifically implausible given current materials and manufacturing limits. There is zero evidence supporting this conspiracy, and health authorities worldwide confirm vaccines contain no microchips, trackers, or surveillance devices.

4. Vaccines Don’t Cause New Variants

A common misconception is that vaccines somehow create new virus variants. In truth, variants arise naturally when viruses mutate during replication. According to the CDC and PublicHealth.org, vaccines actually reduce virus spread, limiting opportunities for mutations. Widespread vaccination is a key strategy in preventing new variants, not causing them.

5. No Link to Long-Term Health Conditions

Fears about vaccines causing chronic illnesses such as autoimmune diseases or neurological disorders have been thoroughly investigated and disproven. The CDC and PublicHealth.org both emphasize that there is no credible evidence linking vaccines to long-term health conditions. Rigorous, ongoing safety monitoring and decades of research consistently show that vaccines are safe, effective, and do not increase the risk of chronic disease.

6. Vaccine Deaths Are Exceptionally Rare

According to the CDC, deaths directly attributable to vaccines are so rare they are statistically negligible. Every reported adverse event is rigorously investigated by health authorities to ensure public safety. The overwhelming majority of vaccines are administered without serious complications, confirming that vaccines remain among the safest preventive tools in modern medicine.

7. Historic Disease Drops Thanks to Vaccines

The impact of vaccines on public health is undeniable. After the introduction of the measles vaccine, cases in the U.S. dropped by over 99%, and the incidence of invasive Haemophilus influenzae type b (Hib) disease in children declined by more than 99% as well. According to PublicHealth.org, these dramatic reductions highlight how vaccines have transformed once-devastating diseases into rare occurrences, saving millions of lives and preventing widespread suffering.

8. VAERS Reports Are Not Proof of Causation

The Vaccine Adverse Event Reporting System (VAERS) serves as an early warning system for possible vaccine side effects, but its reports do not confirm causation. Anyone can submit a VAERS report, and entries are not automatically verified or investigated as evidence of harm. The CDC cautions that VAERS data should be interpreted carefully and in context with thorough scientific review.

9. Vaccines Outperform Natural Immunity

Although recovering from infection can provide some immunity, studies consistently show vaccines offer more reliable and longer-lasting protection. According to Britannica and the CDC, vaccinated individuals have lower rates of severe illness and fewer breakthrough infections compared to those who rely on natural immunity alone. Vaccines train the immune system safely, without the risks associated with disease complications.

11. Updated Vaccines Target Latest Variants

For the 2024-2025 season, COVID-19 vaccines were specifically updated to target the JN.1 Omicron lineage, ensuring protection against the most prevalent strains. The CDC recommends these updated vaccines for all adults, especially those at higher risk. Staying current with vaccination keeps communities safer and strengthens collective immunity as the virus evolves.

12. Misinformation Drives Hesitancy

Recent research published in Scientific Reports demonstrates that exposure to conspiratorial misinformation directly reduces vaccine acceptance. Misinformation spreads rapidly and can undermine public confidence in lifesaving immunizations. This underscores the necessity of relying on credible, science-based sources to guide personal and community health decisions in an era of information overload.

13. Vaccines Drastically Reduce COVID-19 Deaths

Real-world monitoring data consistently reveal that vaccinated individuals are far less likely to die from COVID-19 than their unvaccinated peers. The CDC’s Vaccine Safety reports affirm that vaccines significantly lower the risk of severe outcomes, including hospitalization and death. As a result, communities with higher vaccination rates experience dramatically fewer fatalities, highlighting the life-saving power of immunization in the ongoing pandemic.
