Objectives Highly effective vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been developed but variants of concerns (VOCs) with mutations in the spike protein are worrisome, especially B.1.617.2 (Delta) which has rapidly spread across the world. We aim to study if vaccination alters virological and serological kinetics in breakthrough infections. Methods We conducted a multi-centre retrospective cohort study of patients in Singapore who had received a licensed… 
Influence of the Delta Variant and Vaccination on the SARS-CoV-2 Viral Load
TLDR
By effectively reducing the NP VL, vaccination could allow for limiting viral spread, even with the Delta variant, and suggest that Delta infections could lead to higher VL and for a longer period compared to Alpha infections.
Effect of Delta variant on viral burden and vaccine effectiveness against new SARS-CoV-2 infections in the UK
TLDR
The effectiveness of BNT162b2 and ChAdOx1 against infections with symptoms or high viral burden is reduced with the B.1.617.2.2 (Delta) variant, and the effectiveness of two doses remains at least as great as protection afforded by prior natural infection.
SARS-CoV-2 Variants, Vaccines, and Host Immunity
TLDR
Both SARS-CoV-2-induced host immune activation and vaccine-induced immune responses are reviewed, highlighting the responses of immune memory cells that are key indicators of host immunity.
Infection With the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Delta Variant Is Associated With Higher Recovery of Infectious Virus Compared to the Alpha Variant in Both Unvaccinated and Vaccinated Individuals

TLDR
Infection with the Delta variant was associated with more frequent recovery of infectious virus in vaccinated and unvaccinated individuals compared to the Alpha variant but was not associated with an increase in disease severity in fully vaccinated individuals.
Viral loads of Delta-variant SARS-CoV-2 breakthrough infections after vaccination and booster with BNT162b2.
TLDR
Analysis of viral loads of over 16,000 infections during the current, Delta-variant-dominated pandemic wave in Israel found that BTIs in recently fully vaccinated individuals have lower viral loads than infections in unvaccinated individuals, and that the effect of BNT162b2 on reducing BTI viral loads is restored after a booster dose.
Comparison of infectious SARS-CoV-2 from the nasopharynx of vaccinated and unvaccinated individuals
TLDR
Time-to-event analysis with Kaplan-Myer curves revealed that protection from culturable infectious virus waned significantly starting at 5 months after completing a 2-dose regimen of mRNA vaccines, having important implications in timing of booster dose to prevent onward transmission from breakthrough cases.
Infection with the SARS-CoV-2 Delta Variant is Associated with Higher Infectious Virus Loads Compared to the Alpha Variant in both Unvaccinated and Vaccinated Individuals
TLDR
The data indicate that the Delta variant is associated with increased infectious virus loads when compared to the Alpha variant and decreased upper respiratory antiviral IgG levels.
Epidemiology Features and Effectiveness of Vaccination and Non-Pharmaceutical Interventions of Delta and Lambda SARS-CoV-2 Variants
TLDR
The epidemic characteristics and prevention and control measures for Delta and Lambda, and the effect of vaccination on the SARS-CoV-2 virus, especially the current predominant strain of Delta variant, has become the focus of global concern.
Effect of Covid-19 Vaccination on Transmission of Alpha and Delta Variants.
TLDR
Vaccination was associated with a smaller reduction in transmission of the delta variant than of the alpha variant, and the effects of vaccination decreased over time, similar to those in unvaccinated persons by 12 weeks in index patients who had received ChAdOx1 nCoV-19 and attenuating substantially in those who hadreceived BNT162b2.

BNT162b2 mRNA Covid-19 Vaccine in a Nationwide Mass Vaccination Setting
TLDR
This study in a nationwide mass vaccination setting suggests that the BNT162b2 mRNA vaccine is effective for a wide range of Covid-19–related outcomes, a finding consistent with that of the randomized trial.
COVID-19 therapies and vaccine landscape
Within a few weeks of the novel coronavirus genome sequence being published, numerous therapies and vaccines have entered clinical trials with a few showing great promise in alleviating symptoms and
