Effectiveness of two coronavirus disease 2019 (COVID-19) vaccines (viral vector and inactivated viral vaccine) against severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection in a cohort of healthcare workers

Alexandre R. Marra et al.

Summary: This study investigated the real-world effectiveness of the Oxford-AstraZeneca (ChAdOx1) and CoronaVac vaccines against SARS-CoV-2 infection among healthcare workers in Brazil. The results showed that both vaccines significantly prevented COVID-19, but CoronaVac was much less effective. Additionally, both vaccines reduced hospitalizations and the need for mechanical ventilation, and were effective against the dominant gamma variant.

Summary: This study used computational tools to evaluate the infectivity, transmission, and pathogenicity of the Omicron variant and its sub-variants. The research found that the Omicron and sub-variants have multiple mutations in the receptor-binding domain, increasing their affinity for human ACE2 and potential for transmission. However, mutations in the spike protein's N-terminal domain may result in less impact on the lower respiratory tract. Some mutations in the sub-variants of Omicron seemed to restore the binding effectiveness to ACE2.

Summary: The S protein of SARS-CoV-2 may exploit multiple receptors for infection and interact with both immune and non-immune cells through C-lectin type receptors (CLR), toll-like receptors (TLR), neuropilin-1 (NRP1), and glucose regulated protein 78 (GRP78), potentially driving severe immunopathological inflammation and facilitating systemic spread of infection. Targeting these receptors, as well as other receptors such as Toll-like receptors (TLRs), CLR, Ezrin, and dipeptidyl peptidase-4, could provide therapeutic targets against COVID-19 by enhancing anti-viral immunity and viral clearance.

Surveillance for Adverse Events After COVID-19 mRNA Vaccination

Nicola P. Klein et al.

Summary: This study conducted interim analysis of safety surveillance data of mRNA COVID-19 vaccines and found that the incidence of selected serious outcomes within 1-21 days post-vaccination was not significantly higher compared with 22-42 days post-vaccination. Surveillance is ongoing despite wide confidence intervals for many outcomes.

Effect of 2 Inactivated SARS-CoV-2 Vaccines on Symptomatic COVID-19 Infection in Adults A Randomized Clinical Trial

Nawal Al Kaabi et al.

Summary: This interim analysis of an ongoing randomized trial in the UAE and Bahrain evaluated the efficacy of two inactivated COVID-19 vaccines in preventing symptomatic cases and adverse events in healthy adults. The study found that both vaccines significantly reduced the risk of symptomatic COVID-19 compared to the control group, with efficacy rates of 72.8% and 78.1%. Serious adverse events were rare across all groups.

Immune responses against SARS-CoV-2 variants after heterologous and homologous ChAdOx1 nCoV-19/BNT162b2 vaccination

Joana Barros-Martins et al.

Summary: A study found that booster vaccination with BNT162b2 in healthcare professionals previously vaccinated with ChAdOx-1 nCoV-19 elicited more neutralizing antibodies and higher frequencies of virus-specific T cells. Additionally, BNT162b2 induced high titers of neutralizing antibodies against variants of concern, such as B.1.1.7, B.1.351, and P.1.

SARS-CoV-2 variants, spike mutations and immune escape

William T. Harvey et al.

Summary: The evolution of SARS-CoV-2 has been characterized by the emergence of mutations and variants that impact virus characteristics. Manufacturers are preparing for possible updates to vaccines in response to changes in the virus population, and it is crucial to monitor genetic and antigenic changes alongside experiments to understand the impacts of mutations.

Summary: The study found that autonomy frustration is associated with lower willingness to get vaccinated and a shift from self-determined to external motivation. In Israel, a country with vaccine passports, people reported greater autonomy frustration compared to the UK, a country without vaccine passports.

Summary: Antivirals and knowledge from previous outbreaks like SARS and MERS are considered the most effective way to combat the coronavirus outbreak, especially with the considerable mortality caused by SARS-CoV-2. The ongoing viral mutations have led to different waves of SARS-CoV-2, highlighting the need for effective therapies and antivirals.

Immunological mechanisms of vaccine-induced protection against COVID-19 in humans

Manish Sadarangani et al.

Summary: Most COVID-19 vaccines aim to induce immune responses, particularly neutralizing antibodies (NAbs), against the spike protein of the virus. mRNA vaccines have shown efficacy after just one dose, while adenovirus vaccines elicit polyfunctional antibodies and strong T cell responses. These findings suggest that protection may not solely rely on NAbs but also involve other immune effector mechanisms.

Viral targets for vaccines against COVID-19

Lianpan Dai et al.

Summary: The urgent need for vaccines to control the COVID-19 pandemic has led to the rapid development of multiple vaccine candidates, with some showing positive results in late-stage clinical trials. This article discusses the viral elements used in these candidates, the reasons why they are good targets for the immune system, and their implications for protective immunity. Dai and Gao highlight the importance of selecting the right viral targets in vaccine development to ensure an effective immune response and the overall safety and efficacy of the vaccine.
