He mentioned that the vaccines long term side effects are as yet unknown. This is a completely valid point. Long term studies take years to complete. Live attenuated vaccines have been around for decades and he said he would be willing to take it should one be developed. I find this to be a perfectly reasonable position. He is fully entitled to err on the side of caution when it comes to his health.
I am not sure if The Black Knight or you are aware but a live attenuated Covid19 vaccine is currently under development. If this is to become widely available over the next number of years, I think it may sway the vast majority of remaining unvaccinated to take this jab.
With all due respect, you have no idea what The Black Knight knows either. The tendency I have seen from the vaccinated is to label the unvaccinated as dumb or misinformed. This is not at all my experience. Typically the vaccine hesitant I've met are more familiar with vaccine studies and more aware of their own Covid risk than the vaccinated.
Speaking to one nurse I asked her why she was unvaccinated and she told me while she has seen the first hand risk of Covid in the elderly, vulnerable, she thinks her own risk is low. She is not wrong. Her risk of catching and being hospitalised with Covid over a 30 day period at any time is approximately 1 in 10,000. She asked me to show her a study that shows that her risk of serious harm from the vaccine is lower than her risk of hospitalisation. I couldn't do this because the trials weren't big enough. They weren't big enough to show the vaccines caused Myocarditis or other side effects we now know about. I've posted links as to how small the Pfizer trials before FDA approval were. To reduce vaccine hesitancy one item we need is proof the vaccines reduce hospitalisations without causing serious harm.
