Pennsylvania school districts linked parents to anti-vaccine sites as immunization gaps widened

A Pittsburgh Post-Gazette investigation found that at least 20 Pennsylvania school districts linked parents to Vaclib.org, an anti-vaccine site, via exemption forms as vaccination rates fell and herd immunity weakened in dozens of elementary schools. While a state ad campaign aimed to boost immunizations, districts broadly shared the misinformation—some without realizing it—that then was removed after media inquiries. The findings highlight a lack of centralized oversight and enforcement of vaccine laws in Pennsylvania, and raise concerns about contributing to measles risk as districts face divergent messaging about vaccines.

Bundibugyo Ebola Outbreak in Congo-Uganda: No Vaccine, No Approved Treatment

Bundibugyo Ebola Outbreak in Congo-Uganda: No Vaccine, No Approved Treatment

The Bundibugyo strain of Ebola spreading in the Democratic Republic of the Congo and Uganda has no approved vaccine or specific treatment. The World Health Organization has declared a public health emergency with more than 250 suspected cases and about 80 deaths, and numbers are likely to rise. This strain is less common than the Zaire Ebola virus, which does have vaccines; past Bundibugyo outbreaks (Uganda 2007, Congo 2012) were smaller. Symptoms can include fever, fatigue, muscle pain, and bleeding, with a 30–50% fatality rate; early intensive supportive care can improve survival. An American doctor has tested positive and several others are believed exposed. No Bundibugyo-specific vaccine is close to deployment.

Ticks and temperatures rise: scientists warn of a tough year for Lyme and tick-borne diseases

Ticks and temperatures rise: scientists warn of a tough year for Lyme and tick-borne diseases

As weather warms, scientists warn 2026 could be a bad year for Lyme disease and other tick-borne illnesses, with April recording the highest tick-bite emergency-room visits in years across most U.S. regions. Warmer, humid conditions driven by climate change, plus more deer and white-footed mice as hosts, are fueling tick populations. A Lyme vaccine is in development but isn’t a silver bullet and would require multiple doses; in the meantime, prevention remains essential: avoid tick habitats, use permethrin-treated clothing and repellents, check for ticks, shower after outdoor exposure, and inspect pets.

Vaccines Might Lower Dementia Risk Through Trained Immunity, Researchers Propose

Vaccines Might Lower Dementia Risk Through Trained Immunity, Researchers Propose

A growing body of evidence links routine vaccines (including flu, shingles, RSV, Tdap, pneumococcal, hepatitis A/B, and typhoid) with lower dementia risk. A leading hypothesis is that vaccines train the innate immune system via epigenetic changes, enabling stronger, non-specific responses that may reduce brain inflammation and slow cognitive decline. While data from BCG studies and population analyses support the idea, the exact mechanisms remain unproven and require more research. If validated, this could broaden understanding of vaccine benefits beyond targeted pathogen protection.

DeSantis Delays Redistricting, Adds Vaccine Opt-Out and AI Protections to Agenda

Florida Gov. Ron DeSantis said he would delay a redistricting special session by a week to give his team time to propose a new congressional map that could yield up to five Republican-leaning seats, while adding two items to the agenda: a medical-freedom vaccine opt-out bill and legislation aimed at shielding minors from artificial intelligence, with lawmakers set to meet April 28–May 1.

CDC Accused of Silencing Vaccine Effectiveness Findings

The Washington Post reports that Jay Bhattacharya, the acting CDC director, allegedly blocked the publication of a Morbidity and Mortality Weekly Report study that found COVID vaccines substantially reduce hospitalization and urgent-care visits; Bhattacharya cites methodological concerns, while critics tie the move to broader antivaccine actions under the administration and RFK Jr.'s rhetoric.

RFK Jr.'s Lyme pledge collides with vaccine history as Pfizer pushes a new jab

RFK Jr., as HHS secretary, pledges stronger action on Lyme disease with better diagnostics and treatment, but his anti-vaccine stance complicates Pfizer/Valneva’s plan to file a Lyme vaccine—the first in more than two decades. The prior Lyme vaccine Lymerix faced safety questions and weak uptake, illustrating the challenges Pfizer now faces, even as Lyme incidence rises with climate-driven tick expansion and researchers pursue vaccines and other preventive tools.

New Four-Dose Lyme Vaccine Shows About 70% Protection

New Four-Dose Lyme Vaccine Shows About 70% Protection

Pfizer and Valneva announced phase 3 results for PF-0730740, a four-dose Lyme disease vaccine that achieved about 70% efficacy in preventing infection among people aged 5+ across the US, Canada, and Europe. The regimen requires four injections (two two months apart, then months five–nine, then one year later) and the vaccine is not yet approved; its impact on disease complications is unknown, but it could offer meaningful protection for those in endemic areas while continued tick-prevention steps remain important.
