So explain this: 8 members of the NY Yankee organization have tested positive. All of them had the JNJ shot. See, https://sports.yahoo.com/yanke...-week-205224275.html
1) Was the vaccine batch adulterated? 2) Did they not really get the vaccine? 3) What is the explanation for this?
J&J has a 74% effective rate. However, I believe it's rate in preventing serious hospitalization or death is closer to 100%. Statistical anomalies are to be expected with hundreds of millions of doses. Obviously the close proximity of the players was a factor. One of the expected benefits of the vaccine is to keep people fom dying and out of the hospitals.
The bottom line is your house party is fine but unvaccinated people are going to find that they are going to have to assess the risk of going indoors. They can spread it amongst themselves and lie in their bed (hospital) or coffin. Not us anymore.
Lastly people with children, who currently can't get the vaccine, are gonna have to make decisions about going places with unmasked people when you can't be sure they are vaccinated people.
