We analyzed data from 92,664 clinically and molecularly confirmed Covid-19 cases in Brazil to understand the potential associations between influenza vaccination and Covid-19 outcomes. Controlling for health facility of treatment, comorbidities as well as an extensive range of sociodemographic factors, we show that patients who received a recent influenza vaccine experienced on average 8% lower odds of needing intensive care treatment (95% CIs [0.86, 0.99]), 18% lower odds of requiring invasive… 
Effect of influenza vaccine on COVID-19 mortality: a retrospective study
TLDR
Flu vaccination could reduce the mortality of COVID-19, a pandemic infection with high mortality in older patients due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Relationship between Influenza Vaccination Coverage Rate and COVID-19 Outbreak: An Italian Ecological Study
TLDR
In the Italian population, the coverage rate of the influenza vaccination in people aged 65 and over is associated with a reduced spread and a less severe clinical expression of COVID-19, and this finding warrants ad hoc studies to investigate the role of influenza vaccinations in preventing the spread of CO VID-19.
Association between Exposure to Influenza Vaccination and COVID-19 Diagnosis and Outcomes
TLDR
In COVID-19 patients, overall, IV did not affect outcomes, although a protective effect was observed for the elderly receiving IV almost in parallel with the SARS-CoV-2 outbreak.
Impact of the influenza vaccine on COVID-19 infection rates and severity
TLDR
Influenza vaccination is associated with decreased positive CO VID-19 testing and improved clinical outcomes and should be promoted to reduce the burden of COVID-19.
Positive association between COVID-19 deaths and influenza vaccination rates in elderly people worldwide
TLDR
A positive association between COVID-19 related deaths and influenza vaccination rate (IVR) in elderly people worldwide showed a positive association, and additional work on this line of research may lead to prevention of deaths associated with CO VID-19.
The effect of influenza vaccine on severity of COVID-19 infection: An original study from Iran
TLDR
It seems that patients with previous history of flu vaccination may experience less laboratory abnormalities in some parameters that could be interpreted in favor of lower overall inflammation; however, this study cannot answer this definitely because of its design.
Impact of Recommended Maternal Vaccination Programs on the Clinical Presentation of SARS-CoV-2 Infection: A Prospective Observational Study
TLDR
It is reinforced the importance of maternal vaccination programs in the actual pandemic and health education campaigns should be specially targeted to groups less likely to participate in these programs, as well as for a future SARS-CoV-2 vaccination campaign.
Recombinant adjuvanted zoster vaccine and reduced risk of COVID-19 diagnosis and hospitalization in older adults
TLDR
RZV vaccination was associated with a 16% lower risk of COVID-19 diagnosis and 32%Lower risk of hospitalization, suggesting RZV elicits heterologous protection, possibly through trained immunity.
Influenza and pneumococcal vaccinations are not associated to COVID-19 outcomes among patients admitted to a university hospital
TLDR
This study shows that influenza and pneumococcal vaccinations did not affect hospitalization, intensive care unit admission and deaths in COVID-19 patients in the overall sample and in those ≥ 65 years.
Association of Influenza Vaccination and Prognosis in Patients Testing Positive to SARS-COV-2 Swab Test: A Large-Scale Italian Multi-Database Cohort Study
TLDR
The study, conducted on the vast majority of the population during the first wave of the pandemic in Italy, showed a 13% statistically significant reduction in the risk of hospitalization in some geographical areas and in the younger population.

Excess of Mortality in Adults and Elderly and Circulation of Subtypes of Influenza Virus in Southern Brazil
TLDR
The reduced immune response to infection, and to vaccination, and presence of comorbidities recommend a special attention to this age group in Brazil, and protection in the pandemic year and great vulnerability during AH3N2 virus predominance is shown.
Baseline Characteristics and Outcomes of 1591 Patients Infected With SARS-CoV-2 Admitted to ICUs of the Lombardy Region, Italy.
TLDR
Patients with coronavirus disease 2019 (COVID-19) requiring treatment in an intensive care unit (ICU) in the Lombardy region of Italy were characterized, including data on clinical management, respiratory failure, and patient mortality.
Association of BCG, DTP, and measles containing vaccines with childhood mortality: systematic review
TLDR
Evidence suggests that receipt of BCG and MCV reduce overall mortality by more than would be expected through their effects on the diseases they prevent, and receipt of DTP may be associated with an increase in all cause mortality.
Immunology of COVID-19: Current State of the Science
TLDR
The current state of knowledge of innate and adaptive immune responses elicited by SARS-CoV-2 infection and the immunological pathways that likely contribute to disease severity and death are summarized.
Can existing live vaccines prevent COVID-19?
TLDR
The stimulation of innate immunity by live attenuated vaccines in general, and oral poliovirus vaccine (OPV) in particular, could provide temporary protection against coronavirus disease 2019 (COVID-19).
Co‐infection in SARS‐CoV‐2 infected Patients: Where Are Influenza Virus and Rhinovirus/Enterovirus?
TLDR
To determine whether coinfections with other respiratory pathogens occur in a significant subset of SARS‐CoV‐2 infected patients in the greater New York City metropolitan area, a real‐time reverse‐transcription‐polymerase‐chain‐reaction amplification system was used.
Co-infection with SARS-CoV-2 and Influenza A Virus in Patient with Pneumonia, China
We report co-infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A virus in a patient with pneumonia in China. The case highlights possible co-detection of known
CD8+ T cell cross-reactivity against SARS-CoV-2 conferred by other coronavirus strains and influenza virus
TLDR
The comprehensive in silico profile of private and public predicted epitopes across coronaviruses and influenza viruses will facilitate design of vaccines capable of protecting against various viral infections and support vaccine development against different virus strains.
Clinical diagnosis of 8274 samples with 2019-novel coronavirus in Wuhan
TLDR
Clinical testing methods for 2019-nCoV require improvement and it is important to treat combined infections and perform rapid screening to avoid cross-contamination of patients.
Epidemiological and clinical characteristics of 99 cases of 2019 novel coronavirus pneumonia in Wuhan, China: a descriptive study
TLDR
Characteristics of patients who died were in line with the MuLBSTA score, an early warning model for predicting mortality in viral pneumonia, and further investigation is needed to explore the applicability of the Mu LBSTA scores in predicting the risk of mortality in 2019-nCoV infection.
