WHO declares Ebola Bundibugyo PHEIC; 600 suspected cases, 139 deaths; RFK vaccine push triggers 15-state lawsuit

WHO's May 17 PHEIC declaration for Bundibugyo ebolavirus spread to 600 suspected cases and 139 deaths across DRC and Uganda as of May 20. The approved Ervebo vaccine targets only Zaire strain, proving ineffective against Bundibugyo, with clinical trials requiring 6-9 months. Simultaneously, attorneys general from 15 US states filed suit to overturn HHS Secretary RFK Jr.'s decision to strip seven childhood vaccines of CDC recommendation status, plunging public health into a multi-front crisis.
