The CDC is doing more than "encouraging" it. They are still actively (trying to) FORCE green card applicants (like my wife) to get the jab. https://www.cdc.gov/immigrantrefugeehealth/panel-physicians/vaccinations.html#covid-19-vaccination

The CDC: "we know the jab causes heart damage"
Also the CDC: "We don't care, you need to get it anyways"
