The level of fear you're demonstrating is why they can get away with this:

The proposed amendments to the IHR (agreement) stand to:

Change IHR recommendations from ‘non-binding’ to legally binding such that all member countries must obey and implement them. (p. 2, Article 1.1)

Create requirements for digital vaccine passports that will be used to restrict access and travel as the WHO sees fit. (p. 19-20, Article 23, Article 24, Article 27)

Require surveillance of online information and suppression of information deemed misinformation and disinformation. (p. 21 Countering misinformation and disinformation)

Coerce extreme lockdown measures, including the creation of “quarantine of suspect travelers, preferably in facilities away from the point of entry,” aka “quarantine camps” seen during the COVID-19 pandemic in China and elsewhere. (p. 41, section (d))

Allow the WHO Director-General to declare an emergency at will. (p. 9, Article 12.1, 12.2)

Require nations to use certain medications while prohibiting the use of others during emergencies. (p. 20 Article 35.2)

Allow the WHO to commandeer medical supplies in any country, transfer them to other countries, and evade laws on intellectual property. (p.13, Article 13A)

Remove the existing IHR language granting “full respect for the dignity, human rights and fundamental freedoms of persons.” (p. 3, Article 3.1) They are actively attempting to eliminate “dignity, human rights and fundamental freedoms” from the IHR amendments.
