Anecdotally, my unvaccinated roommate is Chinese, holds a PhD degree in a very difficult field, and works as a researcher in a FAANG company. I was very surprised to learn that they were unwilling to get vaccinated. They are actually very worried about infection, and have been very careful with wearing masks, disinfecting things, and avoiding in-person contacts whenever possible. They explained that they were mostly worried about the unknown long-term side-effects of the vaccines. Maybe having a PhD degree is correlated with having this kind of caution.
