Yikes, you got the vaccine already? Definitely some unanswered questions with this MRNA technology.
I was reading the FDA report regarding the Pzizer vaccine and it says something along the lines of "it's unclear whether the vaccine will lead to susceptibility to other unrelated viruses, especially as immunity wears off". And it goes on to say it's something that will have to be monitored as the vaccine is rolled out.
So essentially, anyone who's taking the vaccine already is treating themselves as something of a guinea pig.
