The seropositivity rates and the median antibody titre against spike protein was “significantly higher” in those vaccinated with Covishield compared with Covaxin, according to a preprint posted in medRxiv. Preprints…
A preprint of the study carried out by ICMR and Bharat Biotech researchers has been posted in biorXiv. Preprints are yet to be peer-reviewed and published in medical journals. So…
The first serosurvey was carried out in August-September 2020 and the six-month follow-up was carried out in end-January to February 2021. Widespread asymptomatic infection by mid-September when the daily cases…
The results were published in the journal Nature. Both Moderna and Pfizer-BioNTech vaccines showed no significant difference in neutralising activity. Individuals immunized with either Moderna or Pfizer-BioNTech vaccines produce closely…
The results were published online in The Lancet on November 19. The results are based on the study of 560 participants enrolled between May 30 and August 8. Of the…
Pre-existing memory T cells that cross-react with SARS-CoV-2 may only reduce COVID-19 severity cannot prevent infection. The memory T cells are extremely unlikely to prevent SARS-CoV-2 infections. That is just…
Using genome sequencing, researchers at the University of Hong Kong have found a rare instance of reinfection with novel coronavirus for the second time, four-and-a-half months after the first infection.…
A new vaccine candidate construct using chimpanzee adenovirus carrying the full length of novel coronavirus spike protein is able to achieve sterilizing immunity and prevent both upper and lower respiratory…
