New York Yankees vice president of information Jason Zillo said the eight infected members included coaches, staff and a players, seven of whom are asymptomatic. All eight members received a single-dose of Johnson & Johnson's COVID-19 vaccine at least two weeks ago, Zillo said.
It is reported that the test proves that the effective rate of a single dose of Johnson & Johnson vaccine against new coronavirus infection is 72%, and the effective rate for severe new coronavirus infection is 85%. The two doses of the new crown vaccine used in the United States, jointly developed by , Pfizer, and BioNTech, and Moderna, both have an effective rate of 95%.
D. Jonathan Reiner, professor of medicine and surgery at George Washington University , said it is unlikely that you will get the new coronavirus with any of the three vaccines because none of them contain the new coronavirus. However, if someone does become infected after being fully vaccinated, symptoms may be much milder than in someone who was not vaccinated at all. Reiner said the fact that seven of the infected Yankees were asymptomatic showed that the vaccine's role in preventing Covid-19 was "remarkable."
Of the eight members who were infected, only coach Phil Nevin showed symptoms, according to Zillow. He said Nevin feels better now. Is
a "breakthrough" infection case?
reported that there have been reports of "breakthrough" infections in vaccinated populations, but they represent a tiny fraction of the 117 million fully vaccinated people in the United States. In this case, "the resulting infection is more likely to have a lower viral load, likely to be shorter in duration, and likely to have a lower risk of transmission to others." Centers for Disease Control and Prevention (CDC) Director Dr Rochelle Valensky said . And people are still vulnerable to infection even after the shot, because the vaccine doesn't kick in until about two weeks after the last shot.
The New York State Department of Health said Thursday that it has been in touch with Major League Baseball and the Yankees .
The department issued a statement saying it had been informed of cases in New York who were still infected 14 days or more after the last dose of the vaccine. They are investigating these cases, as well as those linked to the Yankees, to further determine if they can identify a "breakthrough infection case" as defined by CDC.
