Governments gave the companies developing the vaccines immunity from consequences out of some hyped up need to have a vaccine developed ASAP. The same vaccine which doesn't actually stop [re]infection even now. Without something changing that even large scale class action lawsuits will go nowhere leaving those suffering whatever consequences both literally and figuratively fucked.

You can't reverse the damage but you can take Ivermectin from the day of your shot and one month after to stop the spike protein dealing damage.

This is probably what I would recommend someone who has to take the vaccine do.

Probably want to do some research on dosages and such though.

Sadly probably not with current medical technology.
