This is fantastic. 99.4% of Undergraduates, 97.8% of Graduates, 95.1% of Faculty, and 92.5% of Staff at Yale University are now fully vaccinated. ZERO cases among Undergraduates. Only three positive cases within the last seven days. This week, Yale has a 0.02% positivity rate.
Classes began on September 1st for Undergraduates. Aspects of life at Yale are beginning to resemble something more like their pre-pandemic form amid high rates of vaccination within the university population and the continuation of some key public health protocols.
A 50,000+ study out of the University of Oxford shows while “breakthrough” infections with Delta have similar viral loads (Ct) to unvaccinated individuals, vaccination DOES REDUCE transmission of Delta and vaccinated individuals are LESS LIKELY to spread the Coronavirus. 🧵
Pre-Delta, vaccination reduced transmission of SARS-CoV-2 from individuals infected despite vaccination, potentially via reducing viral loads. While vaccination still lowers the risk of infection, similar viral loads in vaccinated and unvaccinated individuals infected with Delta
question how much vaccination prevents onward transmission. Researchers here performed a retrospective observational cohort study of contacts of SARS-CoV-2-infected index cases using contact testing data from England. They used multivariable logistic regression to investigate the
Portugal, a country who once had the world’s highest number of COVID-19 cases proportionate to its population, now has the world’s HIGHEST vaccination rate. 84% of Portugal’s population is now fully vaccinated. The country will lift most pandemic restrictions on October 1st.
Note: That is 8.5 million people fully vaccinated, and this has been in a matter of months. The nation went from vaccinating only 7000 citizens a day in January, to three months later 44,000 daily doses in April, and 150,000 doses PER DAY at its vaccination peak on July 12th.
In just a few days, nightclubs and bars will be allowed to reopen to those with a digital vaccination certificate or negative COVID-19 test, after having been shut since March 2020. Digital certificates or negative tests will no longer be mandatory in hotels and gyms, but will
A study out of Harvard shows while breakthrough infections with Delta have similar peak viral loads (Ct) to that of unvaccinated individuals, viral loads decrease faster in vaccinated individuals AND they are contagious for a SHORTER period of time, and harbor less virus overall.
Researchers quantified the course of viral proliferation and clearance for 173 individuals with acute SARS-CoV-2 infections using longitudinal quantitative RT-PCR tests conducted using anterior nares/oropharyngeal samples (n = 199,941) as part of the National Basketball
Association’s (NBA) occupational health program between November 28th, 2020, and August 11th, 2021. Researchers then measured the duration of viral proliferation and clearance and the peak viral concentration separately for individuals infected with Alpha (B.1.1.7), Delta
An analysis of an outbreak of the Delta variant in Ontario, Canada during an indoor event shows there was no further transmission to fully vaccinated household members AND there was NO further transmission from breakthrough cases. Vaccination stopped the train of transmission.🧵
Some considerations to keep in mind. This group IS NOT eligible for COVID-19 vaccination and the outbreak occurred during an indoor high-intensity sports event. There were two distinct COVID-19 exposures on different teams with players under the age of 12. The teams did not play
against each other. Overall, 1 in 3 players on each team were infected (see infographic for more details). There was no further transmission to players on other exposed teams, OR to fully vaccinated household members. Transmission did occur from player cases to 2 of 22 household
Impressive data out of Malaysia. 14.5M participants. RECoVAM study shows full vaccination reduces the risk of infection by 88% and symptomatic disease by 86%.
Overall, the COVID-19 Vaccines cut ICU Admission risk by 83% and Deaths due to COVID-19 by 88% according to the study.
ICR Director Dr. Kalaiarasu said findings by the Real-World Evaluation of Covid-19 Vaccines Under the Malaysia National Covid-19 Immunization Program (RECoVaM) showed that the overall ICU rate amongst fully vaccinated individuals-14 days after the second vaccine dose in a
Reminder: “A change in the spike protein- which allows the coronavirus to enter and infect human cells- that is radical enough to make our vaccine completely ineffective would also, almost certainly, be so extreme as to make the virus non-functional.” -Sarah Gilbert, Oxford Team
In other words, the virus cannot completely mutate as there are only so many changes the spike protein can have before it compromises its functionality and therefore its ability to bind to the ACE2 receptor on the surface of our cells and evade our antibodies at the same time.
“There aren’t very many places for the virus to go to have something that will evade immunity but still be a really infectious virus,” and therefore is unlikely to mutate into a much deadlier variant. Gilbert stated that viruses tend to become less virulent over time as they
