whilst companies are working on the "small molecule" approach, there is a strong fear of taking the Astra Zenica vaccine in the community, it seems that the possibility of dropping dead after taking it is putting people off, (especially women). I myself was worried and the coming side effects were not pleasant, and far worse than any side effects from previous vaccinations.
I'm wondering if the vaccine is just too strong, and giving the body too much of a shock to the system. Maybe if they can reduce the strength of the vaccine and give booster shots every three months to slowly bring the immunity up to scratch & thereby avoid unhelpful deaths .
