The letter should not be cut and paste. It should be tailored to her.
The LC template is good, but you cannot just cut and paste.
They even advise you against such. She need to tailor it to HER beliefs.
Keep in mind the most common objections and rebuttals to those objections.
1. The abortion derived cell line testing. (Be prepared for the “Tylenol talking point.”) My answer to that talking point would be that there is a distinct difference between things that have their genesis and product development with abortion derived cell testing, and those products that were pre-existing (like Tylenol) that some person then decided to later test on abortion derived cells.
2. The code of life argument. Be careful that you don’t misstate science here. Don’t say things like “mRNA alters your DNA.” That’s not precise and isn’t what is happening. Instead, you might argue that mRNA manipulation and cellular manipulation on this level is something that belongs only to God and what God uses in nature. Man-made interference at this level is tantamount to playing God.
3. If you are a pre-tribulation Christian, you might argue from Revelation 13.
4. The Conscience/Faith argument.
5. The Kuyperian Sphere of Sovereignty argument.
Whatever she argues, it needs to be HER deeply held religious beliefs. Don’t just cut and paste what others have written.
“...some person then decided to later test on abortion derived cells.”
It depends if the pharm company paid for the testing. In many cases they did. Then the moral quandary becomes local, not remote, and subsequent use of the vaccine is immoral.
