Why were there no lockdowns and mandated mRNA "vaccinations" then?

How many children died from flu during the 2017-2018 season?
As of April 19, 2019, a total of 186 pediatric deaths had been reported to CDC during the 2017-2018 season. This number exceeds the previously highest number of flu-associated deaths in children reported during a regular flu season (171 during the 2012-2013 season). Approximately 80% of these deaths occurred in children who had not received a flu vaccination this season. For the most recent data and more information visit FluView: Influenza-Associated Pediatric Mortality.
Since flu-associated deaths in children became a nationally notifiable condition in 2004, the total number of flu-associated deaths among children during one season has ranged from 37 (during the 2011-2012 season) to 186 (during the 2017-18 season, as of April 19, 2019); this excludes the 2009 pandemic, when 358 pediatric deaths from April 15, 2009 through October 2, 2010 were reported to CDC.
The 80% unvaxxed factoid is irrelevant. Vaccines were not mandated and most people did not bother. So the 80/20 does not
reflect the value of a vaccine, it reflects the distribution of people who took vaccines. So the flu vaccine basically had zero
impact on the death rate.
