After the kerfuffle yesterday around breakthru reporting with the state’s “typo” on the data released, we should have accurate information today and the state promised that this week it would release more detailed data on breakthroughs, which hopefully will include date of event and age structure.
Physicians in England are not totally intimidated into supporting the teachers’ unions messaging on masking and testing children in an abusive manner. The head of the pediatrics society in the UK comes out strongly against continued excessive testing of children, which only leads to a lot of false and low positives, children being needlessly quarantined and missing school, and spreading anxiety and fear.

A strain of seasonal coronavirus called OC43 is probably the closest in sequence to CV-19. A number of studies have looked at whether seasonal coronavirus infections prompt an adaptive immune response that helps fight against CV-19 infection or disease. This new research suggests that there is some benefit in this regard in persons who have OC43 antibodies. They appeared to develop a response to CV-19 faster and to suffer less serious illness.

And on a somewhat related topic, it appears that various viruses may have interactions among themselves that inhibit or don’t inhibit growth. Prior research, for example, has shown that rhinovirus appears to actually outcompete CV-19. And the absence of influenza suggests that perhaps CV-19 outcompetes that virus. Certainly there is no basis to suggest that steps like lockdowns or masking are eliminating one viral infection but somehow not another similar one. This study examines the relative presence of various viruses from 2015 to 2020, so before and during the epidemic. It finds that influenza type viruses and some seasonal coronaviruses largely disappeared during the epidemic but adenovirus and rhinovirus hung in there. While they indicate that RSV prevalence also was much lower, that is no longer true, as we and other countries have experienced a substantial RSV wave out of season, in our summer. (Medrxiv Study)
In the more good news category, more people smoked and/or existing smokers used more cigarettes during the epidemic. That will certainly improve public health. (Annals Article)
In this study health care workers in Italy were prospectively tested for infection following vaccination. Among around 2000 workers, 33 breakthrough cases were identified, but none were symptomatic. The positive test results were verified. In the same period 8 workers tested positive after experiencing symptoms. The research indicates that there are likely a lot of breakthrough asymptomatic infections. Not clear if these people really have any significant infection or just have virus present in their nasal and throat passages. Their “infections” cleared very quickly. We really need to redefine how we test. (Annals Article)
