Herd immunity protects vulnerable people by limiting disease spread. Learn why vaccines matter—even if they’re not perfect—and what happens when rates drop.
RSV vaccines during pregnancy are safe and protect newborns. Learn how they work, debunked claims about preterm birth, and what the latest studies show.
Thimerosal in flu shots isn’t dangerous—learn how it’s different from toxic mercury, what studies show, and why vaccines are not linked to autism or brain harm.
Despite claims, large studies comparing vaccinated vs. unvaccinated children show vaccines don’t harm kids—and do protect them from serious disease.
There’s no credible evidence linking vaccines to autism—just decades of global research showing they’re safe. Autism’s roots lie in early brain development.
Claims that COVID boosters do not help healthy children are misleading. Vaccination reduces hospitalization and severe outcomes, including MIS-C.
Multiple childhood vaccines, including HPV, polio, and measles, were tested in placebo-controlled trials. RFK Jr.’s claim that only COVID was tested is false.
Do vaccines contain RoundUp? A viral video says yes—but flawed testing and basic science say no. There’s no credible evidence glyphosate is in childhood vaccines.
Vaccines are not linked to SIDS, autism, or asthma. The CDC confirms that on-time shots do not raise infant death or chronic conditions.
COVID vaccination has saved millions of lives in the U.S. and reduces severe illness in children. VAERS listings are not proof of causation.
