This kind of report/news is very lame. This is basic science. Very basic knowledge/understanding about vaccine and how vaccine works. This is nothing new.
This kind of news is like telling me “water is liquid, poop stinks and don’t eat poop!”
This makes me sad because this is our reality. Major of population does have enough education but still hold certain positions in society. That we need to make sure to label hot coffee with “caution hot” and to label laundry detergent with “this is not food”.
