A lot of misinformation is circulating about the J&J vaccine. It works by infecting your body with an adenovirus that allegedly can’t reproduce. When it infects your cells, it forces them to produce spike protein. Your body then creates antibodies against these proteins. If you have an immunity to a similar adenovirus, most of the vaccine will be killed off. Likewise, after being vaccinated, your body develops an immunity to the vaccine. The only differences with the mRNA vaccine in antibodies would arise from slightly different spike proteins being generated by the cells. The rest of the antibodies are gained from the rest of the COVID virus, but those don’t exist in the adenovirus, so there’s no way it uses creating them. At most, the antibodies against the adenovirus might have some little incidental effect. If it were a large effect then we’d expect tons of people to have immunity and covid would not be novel. Finally I’ll add that J&J is hardly “traditional”. Despite the marketing, only two other viral vector vaccines have been created for humans —- they were both emergency Ebola vaccines released in 2016 and 2019 respectively. 3-5 years and two emergency vaccines is hardly what anyone would believe traditional means.
