One of the real problems for anyone wanting to understand the pros and cons, is getting any valid information. For example, the chart you show states, "Key Facts ... both mRNA vaccines are greater than 94% effective ... etc."

The current Secretary of State for Health and Social Care here in the UK went on radio a couple of weeks ago to say, "the [mRNA] vaccines are up to 75% effective ..."

So which is it? >94% or <75% ?
Someone, somewhere is just making up the numbers.
Doesn't build trust.

It was 94% against the original coronavirus strain. Since then, there are mutant strains so the vaccine’s effectiveness vary.
