Public health experts told the Financial Times in late May that regional lockdowns, reduced social interaction and an increasing number of antibodies against Covid among the general population were helping to bring down the infection rate in India. Vaccinations too have helped to continue the downward trend in cases.
More.
Cases per million plummeted 91% between May 7 and July 23, at which point just 7% of India's massive population of 1.3 billion had been fully vaccinated.
The vaccines had nothing to do with the crash in cases, but they may have helped cause this debacle in India.
Vaccination temporarily weakens the immune system, making it more vulnerable to infection, which is why it is inadvisable to vaccinate en masse when infections are raging around you. Mind you, in India on February 18th they were not. It would have been as safe a time as any to start vaccinating.
Yet is it mere coincidence that the massive explosion in cases in India after the approximate bottom around February 18th dovetails perfectly with the commencement of mass vaccinations in India around February 13th?
Well?
I think Nottle.
As for the antibody hypothesis, the faith placed in it after all this time is quite simply precious.
Antibody tests can miss previous COVID-19 infection
Antibody tests do not reliably confirm that someone has had COVID-19, which means global estimates of infection rates are likely inaccurate, according to researchers. "We studied the blood of over 120 people with confirmed COVID-19 and measured levels of antibodies ... using 14 different tests" up to three months after diagnosis, said Michael Peluso of the University of California, San Francisco. "All of these people definitely had COVID-19, but not all of them had positive COVID-19 blood tests." The accuracy of the tests at confirming prior COVID-19 varied by how sick the person had been, how much time had passed since the illness and which test had been used. "People who were less sick and in whom more time had passed were less likely to test positive using certain tests," Peluso said. "Since most people have mild (or even asymptomatic) infection with SARS-CoV-2, this study has important implications for our interpretation of several of the large studies that have been done ... to try to estimate the number of people who have had COVID-19." In a report published on Friday in the journal Science Advances, his team advises, "Individual patients or providers using these assays to assess the presence or absence of prior infection and/or immune status should take these considerations into account, given the poor negative predictive value of some tests."
