Ethics board have already discussed the topic at length, where you "argue" with a single sentence - but ok, let's admit vaccination obligations are unethical. Then you do admit infecting others is unethical as well? Now, science has advanced far enough we can retrace who I texted who through genetics; therefore, if you want to abandon compulsory vaccination, it must be compulsory that each and every infection must be investigated like a poisoning is and people who infect others be prosecuted as severely as polluters.
