Seven physicians across immunology, pediatrics and primary care answered common vaccine questions, stressing that safety is tested before approval and monitored continuously after rollout.
CDC-backed examples anchored their case: severe allergic reactions occur at about 1 per million doses, mRNA vaccines do not alter DNA, and flu shots cannot cause influenza.
The experts said many fears persist because social media amplifies dramatic anecdotes, while a retracted 12-child study still fuels the false autism claim despite decades of contrary evidence.
They also pointed to disease-specific benefits, including Shingrix being up to 97% effective and HPV vaccination preventing high-risk strains tied to cancer, with catch-up shots advised through age 26.
The broader message was that vaccines often reduce severity rather than block every infection, and delaying or skipping shots leaves both individuals and communities more vulnerable to preventable disease.
