Those vaccines have had years of use behind them. The coronavirus mRNA vaccines are a completely new technology and haven't even been given anything past emergency approval. This is an apples and oranges comparison.
There have been mRNA vaccines in human clinical trials for around 10 years and they have been studied for around 30 years. There are countless examples of other non-controversial medicines developed and studied for far shorter lengths of time.
I trust you will stop just-asking-questions at that time?
And no approval. In other words, this is a dangerous class of drug that has failed to obtain a single human-use approval in 30 years. Thanks for the info!
