Many liberals are accusing those who are against mandatory* covid vaccination of being hypocrites if they use the slogan "my body, my choice".
* - For the sake of argument I will ignore one facile covid hystericist claim I've seen that vaccination is voluntary unless someone is physically tying you down and injecting you. Apart from being inconsistent with how we use the term everywhere else, it also recalls the puerile quip that freedom of speech exists everywhere - just not freedom after speech.
Quite apart from the possibility that many of the people using this slogan are precisely pointing out liberal hypocrisy by using the slogan, one could easily make an argument which used bodily autonomy (i.e. "my body, my choice") to be against mandatory covid vaccines and at the same time still be anti-abortion.
If you believe that fetuses (to simplify things, assume that we're not counting embryos) are human, then abortion is murder, and with every abortion you're sure that you're killing (at least) one human.
However, with a covid vaccine, refusing to take one does not mean that you are murdering someone, since:
- Covid has an under 1% IFR
- Vaccinated people can still get infected by and transmit covid: the vaccines are very good in protecting those who get them, but are much less effective when it comes to preventing infection and transmission
- The non-vaccinated can take steps to mitigate the risk they pose to others, e.g. getting tested, social distancing and wearing masks (if you believe they work)
- The people the unvaccinated person comes into contact with can be protected from covid by getting vaccinated themselves; relatively few people have medical conditions which mean they can't get the jab (ironically, covid hystericists are very keen to force others to get the jab by saying few people should get medical exemptions, while at the same time pretending that many people have medical exemptions, which is why everyone else gets to get jabbed to protect them)
- People do not typically infect others on purpose and non-consensually (there are covid parties, but here non-infected attendees choose to attend)
- Not being vaccinated does not mean that you have covid
- Even being infected does not mean that you will infect others (superspreaders are responsible for a disproportionate share of transmission)
So there're multiple layers of probability here and we can also apply the principle of double (or even triple) effect - as opposed to abortion, in which it is a certainty that you are ending a life (indeed, that is the very aim).
