Yankees rabies outbreak could be bad news for ditch masks

Eight people Worked for the New York Yankees baseball team (including one player)​​ Test positive Covid-19 vaccine-All these vaccines were vaccinated against this virus more than a month ago.

It seems not good but don’t panic. (Or, if you are a Red Sox fan, please stop smiling.) These “breakthrough” cases do not mean that the vaccine will not work, nor does it mean that some vicious new vaccine-resistant variants are flooding the Yankees. . locker room. However, they do mean that it may be too early to take off these masks.

Manager Aaron Boone announced seven cases to the media on Wednesday. On Thursday, the Yankees also arranged for shortstop Gleyber Torres (Gleyber Torres) On the list of Covid-19 injuries-He got the disease in December, has been vaccinated, and tested positive again. Fortunately, of the seven staff cases, six were asymptomatic. Some people find their reason is that the team regularly tests employees and players.

This is the curve ball. Anna Isabel Bento, a disease ecologist at the Indiana University School of Public Health, said: “Breakthrough cases are underreported because many cases are asymptomatic.” “And most people will not be tested unless they need to. Otherwise they will have symptoms.”

Therefore, it is impossible to say how strange the true extent of this team’s outbreak is, because no one knows the denominator-the number of people still infected after vaccination but never sick. The Yankees received a single dose of the Johnson & Johnson vaccine on April 7. This is enough for their immune system to completely resist the virus. But no vaccine is perfect. Bento said: “Johnson & Johnson’s effective rate of preventing hospitalization and death is 100%, the effective rate of preventing severe cases is 85%, and the effective rate of preventing moderate diseases is 72%.” “Therefore, we hope that if vaccinated People who are infected, they probably have no symptoms.”

In order to overcome the raging pandemic, most Covid vaccines have been tested for their ability to prevent serious illness and death. They all did a great job. Sarah Bryant, an epidemiologist and evolutionary biologist at the University of Chicago, said: “But to find out whether this outbreak is consistent with the reported vaccine efficacy, Johnson & Johnson did report the efficacy against infections. You need to compare the occurrence of the two. rate.”

We can almost do it.in Vaccine test, Johnson & Johnson’s researchers actually tested some subjects with asymptomatic infections: whether the people in the test were negative for the virus before Then study whether antibodies to the virus are positive, regardless of whether they are sick or not? About two and a half months after vaccination, 2.8% of the unvaccinated people were asymptomatic.But 0.7% of people Have done vaccination. This is an effect, Reduce relative risk, About 74.2% (with a fairly wide confidence interval, indicating that the statistical power here is only a general level).in a Preprint In the news released earlier this week (not yet under peer review), independent researchers observed the true results of Johnson & Johnson vaccine two weeks after the shooting, and found that out of 1,779 people who were vaccinated, only three The virus that causes Covid-19 is positive. Of the 17,744 unvaccinated people, 128 attended the training. This is a very, very good rate, but not 100%.

The problem is that the Yankees didn’t say how many people were vaccinated overall — the team spokesperson did not answer my question — so it’s impossible to tell whether the eight breakthrough cases were terrible or just comparable to the process (if you will, ( Please forgive the other metaphors of the overall movement).
