The same logic that applies either way the super remote connection to abortion with the covid vaccines applies to other vaccines too. I did a little comparison between these.
For decades, Catholic ethicists have approved of several vaccines in the USA which have some connection to abortion. It is worth comparing these to COVID vaccines. I think that given they can ethically be used, a fortiori the main COVID vaccines can be used. I will compare them on various grounds. I focus on rubella and chickenpox here although Hepatitis A has similar issues to the two of them.
I continue with a chart showing a comparison in the post.
