From the beginning, pharmaceutical companies engaged in the development of COVID-19 vaccine were aware that to defeat the pandemic they had to address proactively virus variants. Moderna in a Nov. 2021 press release (https://investors.modernatx.com/news/news-details/2021/Moderna-Announces-Strategy-to-Address-Omicron-B.1.1.529-SARS-CoV-2-Variant/default.aspx) stated that a 100-µg booster dose of the Moderna approved COVID-19 vaccine is studied for protection against the Omicron variant. In addition, the […]
The FDA reviewed data from Israel from children 12–15 years old who received a booster five months after the primary Pfizer-BioNTech COVID-19 vaccine and is amending the Emergency Use Authorization (EUA) to allow the booster five months after the primary two-dose vaccination for children aged 12–15. In addition, real-world data that has become available provide […]
Several SARS-CoV-2 variants have been identified since the beginning of the COVID-19 pandemic: Alpha (B.1.1.7 and Q lineages) Beta (B.1.351 and descendent lineages) Gamma (P.1 and descendent lineages) Epsilon (B.1.427 and B.1.429) Eta (B.1.525) Iota (B.1.526) Kappa (B.1.617.1) 1.617.3 Mu (B.1.621, B.1.621.1) Zeta (P.2) On November 30, 2021, the U.S. government SARS-CoV-2 Interagency Group (SIG) […]

The Lancet: 34% COVID-19 survivors have neurological and psychiatric disorders By: Dr. Maria Niu Previous case reports had described the altered mental problems and psychiatric disorders in people diagnosed with COVID-19 infection. In the latest study (https://doi.org/10.1016/S2215-0366(21)00084-5) reported by The Lancet Psychiatry on April 6, 2021, the authors confirmed a high incidence of neurological and […]
True or false: Virus variants weaken the effectiveness of COVID 19 Vaccine Coronavirus vaccines have significantly reduced the infectiousness of COVID 19 cases and showed significant protective efficacy against COVID 19. However, the recent reported COVID19 variants B.1.1.7 in the UK and B.1.351 in South Africa are of concern because of their more accessible and […]
Preliminary results from an Israel-based study suggest that one dose of the Pfizer’s vaccine reduces viral load- a key factor in slowing virus spread. Several of the approved to market COVID-19 vaccines are over 90% effective in preventing disease. But no much data have been available about whether vaccinated individuals can still transmit the SARS-CoV-2 […]
Multiple SARS-CoV-2 variants are circulating globally. Several new variants have emerged in the fall of 2020. Many variants are relatively unremarkable. But scientists have been keeping a close watch on three rapidly spreading variants—first identified in the UK, South Africa, and Brazil—which harbor an unusual constellation of mutations. They all share a mutation that affects […]
Moderna announced on January 25 plans for testing two different booster vaccines aimed at the SARS-CoV-2 variant B.1.351 that emerged in South Africa and has now spread to numerous countries. Moderna COVID-19 Vaccine produced neutralizing titers against all key emerging variants tested, including B.1.1.7 and B.1.351, first identified in the UK and Republic of South […]
