WHO guidelines have no force of law in the US.
The US is a party by treaty to the vaccine component of the WHO International Health Regulations (IHR), but the only vaccine covered at present by the IHR is Yellow Fever. It is conceivable that a future emergency with a vaccine-preventable disease (smallpox is the classic example) could come under the IHR, but long before it did the USPHS through the CDC would be issuing binding regulations for the US.
At present, rules about consent and informed consent for vaccination are State matters. The CDC has the authority to regulate under certain conditions, but since at least the 1990s they prefer to advise rather than to regulate.
Now, going against their advice is difficult, particularly under stress, but in 2009 New Hampshire did not adopt the CDC respiratory protection guidance for dealing with H1N1 influenza because it was not based in science, and NH took a more relaxed approach which has turned out to be correct. In 2014 my organization adopted (happily) a much more stringent approach to potential Ebola exposures which the CDC adopted about six weeks later after the Dallas incident.
Hope that helps.
Jim Noble, thank you so very much for your answer and knowledge.
If you’ve read up-thread, you know that in NY my assembly will be voting on making making the Flu AND the HPV vaccines mandatory for children in school. It’s horrific,
Many young Moms are waking up and getting involved in because this issue transcends political parties and truly stupid issues the dems champion.
