I actually did the research and am glad I did. It only furthers my belief in the underlying safety profile of modern vaccines.
The dengue fever, polio and MMR vaccines are live virus vaccines. None of the COVID vaccines under development are, so they do not share a similar risk profile in that regard.
There are numerous studies debunking the H1N1/narcolepsy and MMR/autism relationships.
The swine flu vaccine released in 1976 does have a relationship of causing an increased incidence of GBH of approximately 1 additional case for every 100,000 people who got the vaccine, so your comment there was relevant.
