As for them working, some are, while some are experiencing horrendous affects, including death. There have already been more deaths associated than all the approved vaccines this country has administered. For the Swine Flu they stopped the vaccination program after 25 deaths. We have exceeded that number by a factor of 2000+, yet the vaccines are still being pushed, and in a lot of cases demanded to retain your job or attend the college you were attending previously.
So, saying they work is at best ambiguous. It needs to be stressed that people who freely take these vaccines are guinea pigs in a human trial. Furthermore, those who chose not to be part of this vaccine trial should face no repercussions whatsoever for non participation in these trials.
Even the doctor, Dr. Malone, who was an inventor of the mRNA vaccines has concerns about them:

The deaths you’re claiming are “associated with” the vaccines are deaths that happened at some point after someone got vaccinated. In other words, grandma who’s 95 years old got vaccinated and died a few days or weeks later. Death reported, by law, by healthcare providers to VAERS. Doesn’t matter what she died of; the law says the death must be reported to VAERS.
There have been reports of people in hospice getting vaccinated. Why on Earth would someone in hospice be vaccinated? Yet here they are, and when they die, those deaths go into VAERS as well.
