The novel Corona-virus 19 hit the streets about 15 months ago. Soon, it spread across the continents and countries. The huge hit was in approximately March 2020 in the United States. It took nearly a year for the vaccine, albeit in emergency approved status, to be developed. The US was in a pretty good spot, able to offer vaccines to most anyone that qualified and wanted them. 

Now, the new Pfizer vaccine has been approved for people 12 years old and older. This means we are poised to be well on our way to herd immunity. If people can remain diligent, careful, considerate, and are willing to take the vaccine; perhaps we can put the disaster of 2020 long behind us.
