The development of any pharmaceutical is only the first step and as you pointed-out, can take many years... On top of this, the testing protocols from the various regulatory bodies in any nation can also take years based on the premise that a lot of time is required in order to understand the short and medium terms affects/risks and dangers.... Bear in mind, this does not go far enough to understand or recognize any long term affects.Just like everything else today, societal influencers have found it exceedingly efficient to put people against each other and create division within our society in order to force an idea or agenda. Nothing is ever quite as black and white as you may believe. Just like the yellow vest movement, black lives matter, etc. it's a little bit more nuanced than simply labelling anyone who is skeptical of the current narrative. "You're either a normal person, or an extreme tin foil hat wearing "anti-vaxer".... It's not true.
Believe it or not, you can be skeptical of the safety of a vaccine that would typically take years to develop... but has been pushed out in 8 months without being an "anti-vaxer". These labels are intended to discourage resistance and promote conformity. Funny though, you don't really see skeptics calling you an extremist, impugning your judgment or labeling you for being pro-vaccine. You don't see them trying to persuade you not to take the vaccine.
Oh, and btw, the article in the OP doesn't seem to have much to do with "anti-vaxers". The lawsuit appears to be over their response to the pandemic including business closures, mask mandates and social distancing rules.
The plaintiffs are arguing that the defendants' "extreme, unwarranted and unjustified" responses to the pandemic were "not scientific, nor medically based, nor proven." They also allege government mask mandates can cause "physical and psychological harm," according to the lawsuit.
That said, how can any real confidence be applied to these vaccines for a virus that the experts/authorities deem 'novel'.
Mandating inoculation be mandatory is no different than the gubmint mandating that you be a lab rat
