The majority of the people I come across who aren't vaccinated aren't doing so is because they think Covid is BS (not to say they don't believe it, they just don't care). Those people tend to be on the right. People on different sides of the aisle have different reasons for being anti-vax. If you are on the left and are anti-vax, it tends to be out of concerns of autism (learn more: http://howdovaccinescauseautism.com/). If you are on the right and are anti-vax, it tends to be because of concerns of what is in the vaccine and where the material is sourced from (embryos). A third group has emerged for the vaccine which seems to have looked up the ingredient list and is fearful of the effects of what it will be on their body. I don't fully believe anyone thinks they are going to be microchipped, but maybe I am wrong.
