My daughter is an ER nurse, my niece an RN/PhD researcher who was moved to Covid work the day the virus broke here. What they are reporting as the after effects of the Covid-19 virus is not infections, but clotting issues and organ damage (including the brain). The drugs needed to deal with those are not natural, nor do common antibiotics help. They are for the most part experimenting frantically, trying to keep people alive.

Keep in mind that the flu vaccine is effectively a temporary solution too, about 60% effective and altered for varying strains and repeated each year. This new Covid vaccine is so far apparently 90% effective, and the "enemy" is at least 10 times more deadly than flu.

Everyone needs to make their own informed decision about vaccination, but here is my take - if it is even temporarily effective against this deadly-to-many virus, and research so far has shown it to be safe, we will be in line the very first day it is available to my husband and me. Unless and until someone shows me a science-based reason NOT to take it, I always take vaccines that will protect my immune-chaallenged body.

Off my soapbox now.

Flu virus mutates all the time. That's why we have to get the vaccine every single year. There is a lot of guess work going into development of each year's flu vaccine because it is difficult to know how the virus will mutate before the shots are ready to be administered. So virus mutation is nothing new to humans. Here is an article about the virus mutation and vaccines effectiveness. https://time.com/5927538/covid-19-mutations-vaccines
