Men experience a long-term drop in semen quality after COVID infection, research finds
by European Society of Human Reproduction and Embryology More than three months after suffering from mild COVID infection, men have lower sperm concentrations and fewer sperm that are able to swim, according to new findings presented at the 39th annual meeting of the European Society of Human Reproduction and Embryology (ESHRE). Professor Rocio Núñez-Calonge, scientific advisor...

Millions of patients do not have full recovery of smell or taste senses after COVID infection, study finds
MASSACHUSETTS EYE AND EAR INFIRMARY During the COVID-19 pandemic, many patients experienced a loss of taste and smell during and after being infected with SARS-CoV-2. A retrospective study by researchers at Massachusetts Eye and Ear, a member of the Mass General Brigham healthcare system, investigated the loss of olfactory and gustatory senses and estimated that about a...

Paxlovid Doesn’t Increase Risk for Rebound COVID Infection
Lisa O’Mary February 15, 2023 People who took the antiviral Paxlovid to treat COVID-19 infections were not more likely to get back-to-back bouts of the virus, a new study shows. The findings offer clarity amid concerns that the use of Paxlovid, which works by stopping the spread of the virus in the body, increased the risk of...

COVID infection, and vaccination, linked to heart condition
by Cedars-Sinai Medical Center Credit: Pixabay/CC0 Public Domain Investigators from the Smidt Heart Institute at Cedars-Sinai validated the link between a debilitating heart condition and COVID-19 and, to a lesser extent, a novel link between the same condition and COVID-19 vaccination. Their findings, published in the journal Nature Cardiovascular Research, suggest that a small percentage of patients vaccinated...

Booster for immune protection after COVID infection
by Max Planck Society Test system for the detection of coronavirus antibodies (enzyme-linked immunosorbent assay (ELISA)). Credit: Max Planck Institute of Molecular Physiology When our immune system comes into contact with the SARS-CoV-2 coronavirus, it fights back and produces antibodies. A similar immune response is triggered by coronavirus vaccines. However, there is still little data...

Study shows the maximum risks of COVID infection with and without masks
by Max Planck Society Masks that do not fit tightly at the edges allow air to enter and exit, especially at the nostrils, but also at the cheeks. But even ill-fitting masks still significantly reduce the risk of infection. Credit: Birte Thiede/MPI für Dynamik und Selbstorganisation Three meters are not enough to ensure protection. Even at...

Lung maintains long-term memory of COVID infection
NEW YORK, NY (Oct. 7, 2021)–After infection with SARS-CoV-2, where does the immune system store the memory to provide long-term protection against reinfection? Though numerous studies have examined blood to track immune responses to SARS-CoV-2, a new study of COVID survivors shows that the memory of the infection is primarily stored in T and B cells within the lung and the lymph nodes...

Prior COVID infection doesn’t guarantee good immunity: study
You caught a case of COVID-19 and then you got your first dose of a vaccine. Maybe you now think you are protected from coronavirus infections in the future. Think again: New research shows that prior COVID-19 infection alone doesn’t guarantee a high level of antibodies against the coronavirus or a strong response after just one dose...
