Here's an article I read today which might help a bit.

Here’s why your efforts to convince anti-vaxxers aren’t working | Brooke Harrington | The Guardian

Seems like you need to get someone from her tribe to do the influencing.  Is there anyone she admires who has changed their mind recently?

Edit:  On the tracking devices, ask her if she'd like to give up her electronics since she's so worried about being tracked.  None of the big tech need to inject a chip into us, we are already addicted to our tracking devices aka phones.

God Tik-Tok is the worst when it comes the anti-vaxing crap. We got our BD15 vaccinated, she really didn't get a say, they opened up a shot clinic for her age range and we took her, it was a drive through one so that helped. I would honestly take your BD13 to an actual doctor and have them explain to her about the vaccine and what it really entails. Remind her that just because a person puts on a lab coat and does a Tik-Tok video does not make that an "expert" or even an actual doctor. Also I had a friend whose daughter was pregnant and got vaccinated and has no issues and the plus side her baby could potentially be born with antibodies.
ETA: BD15 breezed through both her shots, her arm was sore on the second one and that was it. BD15 is starting back at in person schooling, but here in CA she will still have to wear a mask even with her vaccine.

The Pfizer vaccine is expected to be authorized in the coming weeks (not just EUA).  

That may not make a difference in her thought process but it does open the door to mandates.  There is plenty of precedent here.

There is also considerably more data available on the COVID vaccines distributed via EUA (on sheer volume) than many authorized that we don't give a second thought. 

If her hang up is the COVID vaccine and not vaccination in general I think that requires a different approach then general vaccine education, though the latter would be helpful either way.

As for bodily autonomy and the power of choice, I wouldn't focus on making the decision for her but on her understanding that decisions have consequences.  

She is free to remain unvaccinated but that status will require her to play by different rules than those in the home that are vaccinated.  It will impact her outside the home, as well (even if locally you see a considerable resistance to the vaccination efforts).

Just remember, consequences are not punishment.

As a parent, you have to do what you have to do to protect your daughter. So do that.

To protect her, she will do virtual learning this year. She'll not get to go shopping or to enclosed public places. No intimate gatherings with friends. She can see them outside with 6 feet of distance between them. She double-masks anytime she has to go anywhere (unless you can find a KN95 mask). 

She has a choice, but that choice comes with consequences. If she really is worried about tracking devices, then you have a calm conversation with her about how her phone is used to mine data and track her internet searches. Then take the phone and give her a flip phone without data. If she's worried about fertility, give her reading assignments from doctors and researchers in the field about how that's not a concern with the vaccine, but very much so is with COVID and men.

What she is is uneducated. You need to provide that education, and consequences. I think a great question to ask her is "if you do get COVID, how much medical intervention do you want?" When she looks at you confused, explain that since she is having trouble trusting health care providers now that you want to know how far she wants the doctors to go to try and save her since there is very limited treatment and intubation is less life-saving and more life-sustaining (in a coma until your body just gives out) and extremely expensive. Y'all will go bakrupt trying to save her, and is she cool with that?

If she is going to make the decision to not get vaxxed, then she needs to think it all the way through. I highly doubt she has, but if that is her decision, then you do everything else you can to protect her.

Ugh. I'm sorry, this is really hard. I understand body autonomy, but the vaccine isn't just about her health. Have you tried bribes instead of threats?

have a wealth of information explaining the science behind the mRNA vaccines, how they work and why scientists were able to develop the COVID vaccine so quickly.  So much better than tik took or right wing conspiracy sites just maybe not as fun.

I would also recommend taking her to a trusted health care provider to discuss the vaccine so that she has facts not conjecture.

I would also start researching and sharing articles on the current case and hospitalization rates.  Fun little facts like the higher the vaccination rate the lower the hospitalization rate.  Or states where the sheep live (blue states) with higher vaccination rates are not running out of icu beds.

unless she's ready to give up all processed foods, all electronics and cosmetics her argument abt future fertility concerns is moot.

finally I'd assign her a research paper on how polio, measles, smallpox & chicken pox have been essentially eradicated, how the polio vaccine was given without any government approval, why and the outcome.

I am sick sick sick to death of the selfishness of antivaxxers.  Your body autonomy is not superior to mine. 

My dad died of Covid in May.  In Florida on a ventilator.  His last words were "I wish I would have gotten the shot".  I have a 12 BD and fortunately we had no fight with her, in fact she was more apprehensive about the poke than the vaccine.  She also had no choice. As soon as she qualified we got her in.  Why? We don't want her to die.  I'm with you that kids (who's brain in NOT finished maturing until 25 ish) is not qualified to make a decision like this.  I don't know if she works or babysits for people but if she does, or spends a lot of time with little ones who are not old enough to get a vaccine, but you could point out she will have a harder time getting work.  
 

Im kinda hardcore about this and I would just take her and force the issue. It's not like buying school supplies, this can have death as a consequence.  Or long lasting health issues.   I respect your judgment as her parent and encourage you to stand tough on this.  

I have covid as I type. I was only partially vaccinated, I am fully now.

I can only imagine how sick I wouldve been without partial protection.

DANG people need to wise up. Hello anti vaxxers the way the world has been the last 18 months wouldve have been our world in entirety without vaccines. Be smart PLEASE.

If you were told one M&M was poisoned among your packet would you eat them? Your small chance of getting sick and dying can be minimized with the vaccine. Choose wisely.

I am pro vaccine, but wanted my pediatricians opinion on my kids getting it. She does recommend it and could tell me why. Maybe take your daughter to the Dr and get the Dr to explain to her why she should get it and why it's safe.

I'm pro vaccines but I'm nervous for my under 13 children getting whatever COVID vaccine gets greenlighted for children. It won't be tested for a long time, nor have years upon years of use and lots of data like flu shots, pertussis. 

I'm also nervous because children get very ill with COVID and lots die from it. 

Maybe show your daughter articles of teens her age on ventilators or severely ill with COVID?

Take it. Tell her no more so called researching by listening to randoms with no specified education on tik tok.  Tell her she can have her phone back after a visit to a doctor who is qualified to give actual medical advice.  
 

My body my choice is a narrative used for abortion rights.  Not a public health crisis due to infectious disease.   These are two completely different things with completely different public and social implications.  Someone posted a meme on my Instagram that those who push vaccines are pro-life, anti gay marriage, and I can't even remember the last one.  How are these different things even comparable or correlated ? Beats me. 
 

Good luck.  A 13 year old who wants to make her own medical decisions and act like an adult, can act like an adult in all aspects of life.  Go get a job and start paying rent kid.  

It's not just about dieing through is it.  A lot of younger people who get Covid and recover from it are suffering from Long Covid and are suffering from a lot of different long term health issues which are having a bigger impact on them and their futures.
