To me the biggest risk is still the unknown, as in not enough experience. They have never been used “in production” until 2020. I saved this post as a favorite and set up a reminder in 2 years and in 5 years about it. Hope there will be nothing to add, and we just got ourselves a mighty vaccines platform at zero long term consequences.
