Do Tattoos Affect Your Immune System Long-Term? Do tattoos affect your immune system long-term? Yes, tattoo ink leaves particles in the skin and nearby lymph nodes and can trigger ongoing, low-level immune responses in some people. However, current human evidence does not show that tattoos measurably weaken the immune system, reduce vaccine effectiveness, or clearly raise cancer risk; those claims remain unproven and are still being studied.

Curious how body art sticks with you beyond the ink? New research shows tattoo particles can linger in skin and lymph nodes—and may even interact with immunity. What does that mean for long-term health and vaccines? Read on. #immunesystem #lymphnodes #tattooink #tattoos #vaccineeffectiveness

2/11 WHY THIS STUDY WAS NEEDED

Co-author #YangjianchenXu (UWaterloo) notes the #FDA authorized these #vaccines without new "clinical data."

"So our study aims to fill up this gap and by examining the real world data," he told CBC K-W.

5/9 While effectiveness against infection waned over time, mRNA vaccines continued protecting against severe illness across multiple strains.

The CDC continued recommending shots for vulnerable populations for this reason.

These findings highlight the potential need for more frequent vaccination to prevent severe COVID-19-associated outcomes.

6/12 The contrast is stark: that same 5% drop would cause millions of measles infections, while a 5% increase would result in only 5,800 cases across the same period—a thousand-fold difference from a seemingly minor shift in vaccination rates.

Heavy-handed federal efforts to commandeer traditional state and local public health powers via spending limitations or enforcement mechanisms face stiff tests under principles of federalism. Public health actors on the front lines of preventable disease outbreaks may legally respond in myriad ways. Federal threats to defund schools in states requiring vaccine mandates, for example, may be met by state-based enforcement of emergency measures to limit access of unvaccinated children or staff to schools during disease outbreaks via state or local PHEs.Reference Gould 48 Multiple states including California and New York limit vaccine exemptions to cases where immunocompromised persons may be at direct risk from inoculation. 49 While some conservative states have adopted antivax laws removing mandates, allowing extensive exemptions,Reference Herricks 50 or inhibiting information-sharing about vaccines,Reference Westwood 51 none actually forbid persons from receiving vaccines (unlike some states prohibiting gender affirming care for minors).Reference Hodge, White, Piatt and Laude 52

8/10 Research suggests it takes two to three years for the immune system to recover from measles. This phenomenon helps explain why deaths from other childhood diseases dropped dramatically after the measles vaccine was introduced in the 1960s.

COVID vaccine provided some protection this winter, even if only 1 in 5 Minnesotans got it Existing immunity to the coronavirus helped keep people out of the hospital.

​The Star Tribune reports that the current COVID-19 vaccine was 33% effective at preventing emergency room and urgent care visits among adults this winter.
