    Abstract Frontline healthcare workers (HCWs) could be at risk for monkeypox infections. Vaccine hesitancy can be found among HCWs and has an impact on their own attitudes towards vaccination. In the context of the exhaustion due to the COVID-19 pandemic, the team around Amandine Gagneux-Brunon aimed to evaluate intentions of HCWs in France and Belgium to get vaccinated against monkeypox. They performed a cross-sectional study using a self-administered online questionnaire evaluate intentions of HCWs to get vaccinated against monkeypox, in case a recommendation for HCW vaccination was given. 397 persons responded. The researchers then compared demographics characteristic, vaccination readiness, eagerness to receive a COVID-19 vaccine, and confidence in HCW with Chi-square tests, student-t and performed a binary regression.

    Abstract Background: Within a few months, the COVID-19 pandemic had spread to many countries and had been a real challenge for health systems all around the world. This unprecedented crisis has led to a surge of online discussions about potential cures for the disease. Among them, vaccines have been at the heart of the debates and have faced lack of confidence before marketing in France.
    Objective: This study aims to identify and investigate the opinions of French Twitter users on the announced vaccines against COVID-19 through sentiment analysis.
    Methods: This study was conducted in 2 phases. First, we filtered a collection of tweets related to COVID-19 available on Twitter from February 2020 to August 2020 with a set of keywords associated with vaccine mistrust using word embeddings. Second, we performed sentiment analysis using deep learning to identify the characteristics of vaccine mistrust. The model was trained on a hand-labeled subset of 4548 tweets.
    Results: A set of 69 relevant keywords were identified as the semantic concept of the word "vaccin" (vaccine in French) and focused mainly on conspiracies, pharmaceutical companies, and alternative treatments. Those keywords enabled us to extract nearly 350,000 tweets in French. The sentiment analysis model achieved 0.75 accuracy. The model then predicted 16% of positive tweets, 41% of negative tweets, and 43% of neutral tweets. This allowed us to explore the semantic concepts of positive and negative tweets and to plot the trends of each sentiment. The main negative rhetoric identified from users' tweets was that vaccines are perceived as having a political purpose and that COVID-19 is a commercial argument for the pharmaceutical companies.
    Conclusions: Twitter might be a useful tool to investigate the arguments for vaccine mistrust because it unveils political criticism contrasting with the usual concerns on adverse drug reactions. As the opposition rhetoric is more consistent and more widely spread than the positive rhetoric, we believe that this research provides effective tools to help health authorities better characterize the risk of vaccine mistrust.

    Abstract Introduction: Pregnant women (PW) are at increased risk of complications due to seasonal influenza and Covid-19. Immunization during pregnancy against pertussis and respiratory syncytial virus (RSV) protects newborns from severe diseases. Our aim was to assess intentions to get vaccinated against seasonal influenza, COVID-19, pertussis and RSV in PW and to identify factors associated with intentions.
    Methods: Cross-sectional survey in PW followed at a University Hospital in France assessing their knowledge, and attitudes toward vaccination against influenza, Covid-19, and RSV during pregnancy. Primary outcome was intention to receive each vaccine or potential vaccine. Univariable and multivariable analysis were carried out to identify factors associated with intentions to get vaccinated for each vaccine.
    Results: Among the 1199 PW followed during the study period, 310 completed the questionnaire. Intentions to get vaccinated were respectively 43.9 %, 36.8 %, 36.1 % and 39.4 % against influenza, Covid-19, pertussis and RSV. Overall confidence in vaccines using 5C-model, recommendation by a healthcare professional (HCP), good knowledge about diseases and vaccines and previous influenza vaccination were associated with flu vaccine acceptance with respective adjusted odds ratios and 95 % Confidence Intervals (aOR) 1.69 (1.09-2.61) by one-point increase in confidence score, 4.89 (2.24-10.7), 1.56 by one-point increase in knowledge score (1.26-1.93), 13.5 and (5.3-34.3). Confidence was also associated with Covid-19 and RSV vaccine acceptance with respective aOR and 95 % CI 2.63 (1.7-4.07) and 1.92 (1.3-2.84). For pertussis, previous flu vaccination or pertussis vaccination in the last 5 years were predictors of pertussis vaccine acceptance during the pregnancy with respective aOR and 95 % CI 1.97 (1.1-3.84) and 2.9 (1.6-5.18).
    Conclusion: Confidence is associated with seasonal influenza, COVID-19 and RSV vaccines acceptance in pregnant women. Receiving a recommendation from a HCP was strongly associated with acceptance of influenza vaccine. Recent vaccination against pertussis was not a barrier to pertussis vaccine acceptance during pregnancy.

    Abstract Thanks to widespread use of antiretroviral therapy worldwide, women living with HIV (WLWH) are becoming pregnant and giving birth to HIV-exposed but uninfected (HEU) newborns. Both pregnancy and HIV infection-related factors such as low CD4+ T-cell count or uncontrolled viral load increase the risk of severe infections such as influenza, COVID-19, and others, making maternal immunization a valuable tool to decrease maternal morbidity among WLWH. Vaccines administered during pregnancy may also benefit the health of HEU infants. Indeed, HEU infants suffer from higher risk of morbidity of infectious origin, including respiratory syncytial virus (RSV), group B streptococcus (GBS), pneumococcus and pertussis infections. Maternal pertussis immunization is recommended in various high-income countries but not in many low-middle income countries where HIV prevalence is higher. GBS and RSV vaccines to be administered during pregnancy are currently in late-phase clinical trials in HIV-uninfected women and could represent a valuable tool to decrease morbidity during infancy. Decreased transfer of vaccine-specific IgG, accelerated waning of vaccine-induced antibody responses, linked to persistent maternal immune activation, and blunting of infant immune response to vaccines could hamper vaccine effectiveness among WLWH and HEU infants. Vaccine hesitancy could limit benefits of maternal immunization and strategies to tackle vaccine hesitancy should be part of HIV routine care. The aim of this review is to summarize the current knowledge regarding the immunogenicity and efficacy of available and upcoming vaccines recommended during pregnancy of WLWH.

    Abstract Pregnant individuals are frequently excluded from clinical trials. Yet, inclusion of Pregnant individuals is of interest in vaccinology including during health crisis. Promotion of clinical trials by midwives may facilitate the decision making of Pregnant individuals. Attitudes of midwives about pregnant individuals participation in a vaccine clinical trial have been little explored. We conducted an anonymous survey from the 11th of September to the 11th of November 2020. Primary endpoint was the willingness to encourage Pregnant individuals to participate in a hypothetical respiratory syncytial virus (RSV) vaccine clinical trial. Among 398 midwives who answered the questionnaire, 113 (28.3 %) were likely to encourage Pregnant individuals to participate in the vaccine clinical trial, this proportion ranged from 25 % in senior midwives to 34.5 % among the students. After adjustment on age, parenthood, previous personal attitudes of vaccine hesitancy, and psychological antecedents of vaccinations (5C-model), the only predictor of the promotion of the clinical trial was the experience of vaccine education (evaluated by a 20-point score) with an adjusted odds ratio of 1.09 (1.01–1.18, p = 0.027) for a one-point increase. Vaccine hesitancy and psychological antecedents of vaccinations were not associated with a lower promotion of pregnant individuals trial participation by midwives. Few respondents were likely to encourage Pregnant individuals to participate in a vaccine clinical trial. Midwives who considered themselves to have a good training about vaccines were more prone to encourage Pregnant individuals to participate in a RSV vaccine clinical trial.

    Title translation Vaccination against influenza, pneumococcus and herpes zoster in the elderly Survey of prescribing physicians: assessment of knowledge and identification of obstacles to the prescription of vaccination.
    Abstract Vaccination coverage is insufficient for influenza, pneumococcus, and herpes zoster in people over the age of 65 in France, even though these are common infectious diseases. Using a computerised questionnaire, the aim of our study was to assess the knowledge of general practitioners, geriatricians, infectious diseases specialists and interns in the Loire region about the vaccination against these three diseases in elderly subjects, to identify the obstacles to vaccination, and to evaluate whether the provision of knowledge modifies the prescriptions and vaccination recommendations made to patients. Of the 125 responses from doctors and interns, 90.2 % are correct for influenza, 69.2 % for pneumococcus, and 32.8 % for herpes zoster, with no significant difference between specialities. By providing information, practitioners are more willing to vaccinate their patients against influenza (99 %), pneumococcus (93 %), and herpes zoster (39 %). The main obstacles to vaccination are the patient's refusal (85 %), the doctor's lack of knowledge and time (70 % and 41 % respectively), doubts about the vaccine's effectiveness (28 %), and fear of side effects (21 %).
