Let's start with your opening remark..."...the nonsense of our health professionals"...IMO, the tens of thousands of people at our CDC, NIH and FDA, and all the many other thousands of Infectious Disease scientists/clinicians around the world have spent decades developing strategies and technologies for combating the viral pathogens that nature throws at us...they have been quite successful in the past, and those same people are working to get us past COVID-19. The longer you persist in referring to those people as "nonsensical", the longer you will be aiding and abetting those who are extending this effort beyond what was needed...the unvaccinated.
As for your risk assessment...I checked today's COVID-19 data and it shows for the U.S....826K deaths over ~2 years (400K+/yr)...that's over 10x the average yearly Influenza toll for the last ten years. Moreover, as you must have seen repeatedly on the news (not just MSM) several states have recently experienced overwhelming cases requiring hospitalization and ICU care...to the point where they have had to request federal assistance (i.e. Doctors and Nurses)...this has never happened with Flu outbreaks in the recent past..or since 1918...if I have to emphasize the seriousness of this any further, I'm outta here ;-)...assuming you agree, then let's keep going...
You talk about young people having very low likelihoods of serious illness, and older people representing the majority of deaths...this is true...however...we live in a society where all age groups mingle...there's no way, short of internment camps to keep the most vulnerable age groups separated from the others. You'll have to take my word for it, but many millions of people over age 60 ar either working, vacationing or just playing golf amongst the younger members of society...they're not all in nursing homes...consequently, because COVID-19 is a very transmissible virus, it's incumbent on everyone to do the best they can to stop the spread...i.e. get vaccinated and mitigate (masks...social distancing)...until those 'modalities' achieve what's called an "Endemic" situation where COVID-19 is no more "Virulent" than the Seasonal Flu (e.g. one measure being death rate...on the order of ~35K/year)...I'm not saying that's a hard and fast target, but hopefully you get the picture...oh, let's not forget that all infected people can spread the disease, and many of the younger cohort will be asymptomatic, so yes, they are at low risk, but are also a potentially high risk for others they come in contact with who are older and not in world-class physical condition...(part of the reason Pro teams are cancelling games...they see local outbreaks among players and coaches and don't want to become mini-supers spreaders).
Note that as we speak, New York City has just experienced 20,000 COVID cases in ONE DAY...and as much as 20% is from the new Omicron variant...for a new variant to move from near zero cases to 20% in a matter of a couple of weeks is troubling....we can only hope that the cases don't lead to the same level of serious illness as Delta, but hope is not a strategy, so no change in vaccination or mitigation efforts is warranted until sufficient data is available...btw, perhaps because so many of the older members of society have gotten vaxxed and boosted, the case load in NYC has shifted to the lower age groups...we'll see what that means for ICUs shortly.
As for the future, who knows what will happen, but we know vaccines keep people out of ICUs and morgues...absolutely NO DEBATE on that point, so if we keep increasing the percentage of vaccinated people (all over the world), the sooner we'll get to a condition where COVID-19 is "Endemic", i.e. still around, BUT...the effects are largely mild, with a 'familiar' death rate (see above). How much restriction gets imposed depends on the numbers...how many hospitalizations, ICU beds and deaths are we seeing...you think you're frustrated and burnt out...how would you like to be our family ICU Doc and have to work your butt off every working day for two years straight, WITH RISK TO THEMSELVES AND THEIR FAMILIES, to try and save people who won't even save themselves with a simple shot in the arm?
Hang in there...and place your trust in the folks who have always dedicated their lives to keeping you as safe and healthy as possible...and thanks for participating in the Pfizer trials!!
