NATO Countries Send Troops to Greenland After U.S. Talks Collapse

But the experiment’s protocols not only legitimize those concerns, they raise them. Inside Medicine found that there’s no placebo in the trial, and that this experiment is studying a vaccine known to be effective in order to find “non-specific effects” of vaccines. That’s language straight from Health Secretary Robert F. Kennedy’s echo chamber, as he and his fellow anti-vaxxers make unfounded claims that many vaccines have unknown harmful effects.

The study is also flawed because hepatitis B causes serious problems later in life, not shortly after birth, so trying to measure mortality and morbidity is not likely to yield any useful conclusions right away. Plus, none of the vaccines in the study are FDA-approved, raising the question of why the CDC is funding a study of vaccines that aren’t available to Americans.

Other issues in the trial include a lack of testing of mothers for hepatitis B, meaning that some of the babies at the highest risk for contracting it could be left without the vaccine, and that there’s no “stop” protocol in case the results are very bad for the participants. The Department of Health and Human Services is defending the study by claiming Guinea-Bissau isn’t mandating the hepatitis B vaccine until 2027 anyway.
