Harboring concern over long term risks of covid because o f lack of data, but unconcerned about long term risks from vaccines for covid because of lack of data? You MAY be brainwashed.
Then there's the risk of an inactivated or weakened virus vaccine causing the disease it's supposed to prevent. That happened in a big way in 1955, with a defective batch of polio vaccine. The mRNA vaccines can't do that - they don't have an entire virus.
There's the Guillain-Barré syndrome with some vaccines, including the Janssen COVID-19 vaccine. If it shows, it does so in the first two months.
