Early Features on South Africa Tshwane District Omicron Variant Patient Profile: absence of any significant increase in in-hospitals deaths in relation to the dramatic rise in the case rate.

There has been a significant rise in new SARS-CoV-2 infections in the Gauteng Province in the last four weeks which has been attributed to the new Omicron variant announced on 24 November 2021. The first cases of Omicron were detected in the Tshwane District and coincided with the sharp rise in new infections, heralding the

The first six months of COVID-19 vaccination campaign in Italy averted 29350 deaths and 4256332 new infections: results published in a paper of Greenwich, Boston and Indiana Universities

In a paper published in MedRxiv are analyzed the effectiveness of the first six months of vaccination campaign against SARS-CoV-2 in Italy by using a computational epidemic model which takes into account demographic, mobility, vaccines, as well as estimates of the introduction and spreading of the more transmissible Alpha variant. Are considered six sub-national regions

Researchers reveal possible role for anti-idiotype antibodies in long-term effects of COVID-19 and some vaccines complications

With around 256 million cases and more than 5 million deaths worldwide, the COVID-19 pandemic has challenged scientists and those in the medical field. Researchers are working to find effective vaccines and therapies, as well as understand the long-term effects of the infection. While the vaccines have been critical in pandemic control, researchers are still

High-titre convalescent plasma therapy not effective against severe COVID-19 pneumonia: results of Italian TSUNAMI randomized clinical trial

1. Amongst patients with severe COVID-19 pneumonia, there was no difference in 30-day all-cause mortality, ventilation or cure in patients receiving convalescent plasma (CP) plus standard therapy versus standard therapy alone. 2. CP treatment was associated with more adverse events, including 5 instances of respiratory failure requiring treatment interruption. Patients who have recovered from SARS-CoV-2

A detailed study by Max Planck Institute shows the maximum risks of being infected by SARS-CoV-2 for different scenarios with and without masks

Three metres are not enough to ensure protection. Even at that distance, it takes less than five minutes for an unvaccinated person standing in the breath of a person with Covid-19 to become infected with almost 100 percent certainty. That’s the bad news. The good news is that if both are wearing well-fitting medical or,

Scientists of Arizona State University discover potential mechanism behind rare blood clots linked to adenovirus COVID-19 vaccines (VITT)

A cloud of platelet factor 4 proteins interacts with the electrostatic surface of the Oxford vaccine, as seen through the computational microscope.  An international team of scientists believe they may have found a molecular mechanism behind the extremely rare blood clots linked to adenovirus COVID-19 vaccines. “The mechanism which results in this condition, termed vaccine-induced

Safety and immunogenicity of booster COVID-19 vaccine following two previous doses of AstraZeneca or Pfizer-BioNTech in the UK

Six different COVID-19 boosters are safe and provoke strong immune responses in people who have previously received a two-dose course of ChAdOx1-nCov19 (Oxford–AstraZeneca [ChAd]) or BNT162b2 (Pfizer-BioNTech [BNT]), according to the first randomised trial of boosters given after two doses of either vaccine, published in The Lancet. ChAd has now been deployed in more than 180
