So you seem to be defending getting medical advice from unqualified facebook posters? I do not believe it is wise to do that.
As far as Individual rights, I support anyone who wants to take a chance on hurting themselves. But their rights end when injuring other people. Those wishing to not vaccinate need not publish lies about vaccines, they should just STFU and not get vaccinated. They should also not be allowed to take icu beds from people who try to help everyone remain safe. Anti vaxers should not be allowed medical care since they do not believe the virus is real/deadly. The simple minded that believed those anti vaxxers but did not push the lies should be allowed all appropriate medical care.
