for every human on earth. Some people feel that the side effects that many people report after their 2nd vaccine shot are too difficult to put up with and therefore not worth getting vaccinated. My wife had these side effects - mild fever, fatigue that lasted for 5 days, chills/sweating, body aches. She most certainly did no like that nor did I becasue I was her nurse maid and I was already playing that role since she broke her ankle a few weeks earlier and I was just tired of being a nurse maid. But we both felt it was well worth it to be 95% or so protected from Covid and we were doing our part for herd immunity and gettoign our society back to some semblence of normality and yes, even helping to protect silly people that are anti vaxxers.
