pneumococcal vaccine adverse effect

In most countries worldwide, pneumococcal conjugate vaccines have been included in the infant immunization program, resulting in a significant reduction in the burden of pneumococcal disease in children and adults. Shifting serotype distribution due to the indirect effect of infant vaccination with the 13-valent pneumococcal conjugate vaccine (PCV13) may continue to increase the gap between 23-valent pneumococcal polysaccharide vaccine (PPSV23) and PCV13 serotype coverage for older adults in the coming years...

Autoimmune and autoinflammatory rheumatic disorders (ARD) are treated with antimetabolites, calcineurin inhibitors and biologic agents either neutralizing cytokines [Tumor Necrosis Factor (TNF), Interleukin (IL)-1, IL-6, IL-17, B-cell activating factor] or being directed against B-cells (anti-CD-20), costimulatory molecules or JAK kinases. Similarly for the influenza or pneumococcal vaccines, there is limited data on the effectiveness of vaccination against SARS-CoV-2 infection and COVID-19 prevention for this susceptible patient population...

BACKGROUND: The widespread use of pneumococcal conjugate vaccines (PCVs) has significantly decreased pneumococcal disease worldwide. However, China has not adopted PCVs in their national immunization schedules and had only approved these vaccines for children aged 2-15 months by 2020. METHODS: In an open-label trial, enrolled healthy children aged 2-5 years old were randomized 1:1 and divided into a 7-valent pneumococcal conjugate vaccine (PCV7) group and a Haemophilus influenzae type b conjugate vaccine (Hib) group...

BACKGROUND: Pneumococcus remains an important cause of morbidity in pregnant women with HIV and their infants. We compared the safety and immunogenicity of PCV-10 and PPV-23 with placebo administered in pregnancy. METHODS: This double-blind, multicentre, randomised controlled trial was done at eight outpatient clinics in Brazil. Eligible participants were adult women with HIV who were pregnant at a gestational age between 14 weeks and less than 34 weeks and who were taking antiretroviral therapy at study entry...

BACKGROUND: Sickle cell disease (SCD) is a group of inherited disorders that result in haemoglobin abnormalities and other complications. Injury to the spleen, among other factors, contribute to persons with SCD being particularly susceptible to infection. Infants and very young children are especially vulnerable. The 'Co-operative Study of Sickle Cell Disease' observed an incidence rate for pneumococcal septicaemia of 10 per 100 person-years in children under the age of three years. Vaccines, including customary pneumococcal vaccines, may be of limited use in this age group...

AIM: Evaluate the effect of PCV13 vaccination on the composition of the microflora of the upper respiratory tract and the immune system in HIV-infected patients. MATERIALS AND METHODS: 100 patients with HIV-infection were included in the study. The patients underwent immunological examination and the collection of biomaterial from the posterior pharyngeal wall for microbiological examination. After obtaining the results of the examinations, PCV13 was intramuscularly administered...

BACKGROUND: An affordable pneumococcal conjugate vaccine (PCV) is needed to ensure sustainable access in low-income and middle-income countries. This trial examined the immunogenicity and safety of a novel ten-valent PCV (SIIPL-PCV) containing serotypes 1, 5, 6A, 6B, 7F, 9V, 14, 19A, 19F, and 23F compared with the pneumococcal polysaccharide protein D-conjugate vaccine (PHiD-CV; Synflorix; GlaxoSmithKline; Brentford, UK). METHODS: In this single-centre, randomised, double-blind, phase 3, non-inferiority trial in The Gambia, healthy, PCV-naive infants aged 6-8 weeks were enrolled and assigned using permuted block randomisation to receive one of three lots of SIIPL-PCV or to PHiD-CV in a ratio of 2:2:2:3...

Pneumococcal infections are an important cause of mortality and morbidity in Chronic Lung Diseases. However, exacerbations, which make the treatment of diseases very difficult, and corticosteroids used during treatment carry a great risk of pneumococcal infection and adversely affect the treatment. The most rational way to reduce the negative impact of pneumococcal infections on the clinical and economic burden of Chronic Lung Diseases is vaccination of the risky population. Although, vaccination recommendations are well defined, recommended by national and international guidelines and are paid by health authorities, in Turkey, vaccination rates in adults with chronic lung disease is far below the expected...

BACKGROUND: Maternal immunization with pneumococcal conjugate vaccine (PCV) may protect young infants in high-risk settings against the high risk of pneumococcal infections in early life. The aim of this study was to determine the safety and immunogenicity of 13-valent PCV (PCV13) in healthy women of childbearing age in PNG. METHODS: As part of this observational study, 50 non-pregnant women of childbearing age (18-45 yrs. old) living in the highlands of PNG were vaccinated with a single dose of PCV13...

BACKGROUND: Prior to introducing pneumococcal conjugate vaccines (PCVs), Streptococcus pneumoniae was most commonly isolated from the middle ear fluid of children with acute otitis media (AOM). Reducing nasopharyngeal colonisation of this bacterium by PCVs may lead to a decline in AOM. The effects of PCVs deserve ongoing monitoring since studies from the post-PCV era report a shift in causative otopathogens towards non-vaccine serotypes and other bacteria. This updated Cochrane Review was first published in 2002 and updated in 2004, 2009, 2014, and 2019...

INTRODUCTION: Although acute otitis media (AOM) is a very frequent illness in children, it remains unclear to what extent children with AOM benefit from antibiotics (ABX). This systematic review aimed to clarify this subject by including randomised clinical trials (RCTs) from the pneumococcal vaccine era only. METHODS: We performed a systematic literature search in four databases from 1 January 2000 to 1 January 2019 for RCTs comparing ABX to placebo in patients with AOM...

Background: Genome plasticity of Streptococcus pneumoniae is responsible for the reduced efficacy of various antibiotics and capsular polysaccharide-based vaccines. Therefore, targets independent of capsular types are sought to control the pneumococcal pathogenicity. UDP-glucose pyrophosphorylase (UGPase) is one such desired candidate being responsible for the synthesis of UDP-glucose, a sugar precursor in capsular biosynthesis and metabolic Leloir pathway. Being crucial to pneumococcal pathobiology, the effect of UGPase inhibition on virulence was evaluated in vitro...

INTRODUCTION: Infants of mothers with substance use disorder (SUD) are exposed to complex social environments and increased childhood health risks that can lead to adverse consequences throughout the lifespan. GunderKids, a voluntary, specialized, comprehensive pediatric care management program, was developed to mitigate many of these adverse consequences. Our organization is evaluating several clinical outcomes related to health and development in children born to women with SUD. The current study addressed the timeliness of vaccination coverage among these infants...

BACKGROUND: A lower conversion vaccination rate and a more rapid decline in antibody titers over time in dialysis patients raise concerns about the effectiveness of pneumococcal vaccination (PV) in this population, which has not been systematically reviewed. METHODS: We searched PubMed, Cochrane Library, Embase and three Chinese databases from inception until February 29th, 2020 for interventional, cohort and case-control studies evaluating PV alone or combined with influenza vaccination (IV) on outcomes (all-cause mortality, pneumonia, cardiovascular events, antibody response and safety)...

Cardiovascular diseases are the leading cause of death in most regions of the world, usually followed by infectious diseases. For decades, infections in general, and particularly those involving the respiratory system, have been known to be associated with an increased risk of cardiovascular and cerebrovascular events, and their consequent morbidity and mortality. Although vaccines are an excellent strategy in the prevention of infectious diseases, the proportion of immunized adults in our country is frankly deficient...

RATIONALE: Pneumococcal colonisation is key to the pathogenesis of invasive disease, but is also immunogenic in young adults, protecting against re-colonisation. Colonisation is rarely detected in older adults, despite high rates of pneumococcal disease. OBJECTIVES: To establish experimental human pneumococcal colonisation in healthy adults aged 50-84 years, to measure the immune response to pneumococcal challenge, and to assess the protective effect of prior colonisation against autologous strain rechallenge...

BACKGROUND: Epidemiological studies suggest that there is a link between pneumococcal infection and adverse cardiovascular outcomes such as myocardial infarction. Multiple studies have evaluated the protective effect of the 23-valent polysaccharide pneumococcal vaccination (PPV23), but results have varied. Therefore, a meta-analysis was conducted to summarize available evidence on the impact of PPV23 on cardiovascular disease. METHODS: A literature search from January 1946 to September 2019 was conducted across Embase, Medline and Cochrane...

INTRODUCTION: Monoclonal antibodies (mAbs) have become an increasing source of biological treatments. Clinicians should make an effort to update their knowledge on mechanisms of action, indications, and adverse events of these novel therapies. Most of them have immunosuppressive effects and, therefore, vaccination is indicated. AREAS COVERED: vaccination of patients under mAbs therapies. EXPERT OPINION: Recommendations on vaccination are still based on expert recommendations and have not been updated in recent years...

Streptococcus pneumoniae is the most frequent source of community-acquired bacterial pneumonia in adults. Respiratory tract infections are the foremost reasons for asthma exacerbations. The World Health Organization and the Centers for Disease Control and Prevention consider asthma a clear indication for pneumococcal vaccination. The aim of this study was to determine the extent to which adult patients with asthma in Poland adhere to a schedule of recommended pneumococcal vaccinations. In addition, the study attempted to assess the source of the patient knowledge on vaccination and the plausible determents for vaccination...

Background: Congenital heart defected (CHD) children are often predisposed to numerous conditions ranging from arrythmias, infections, to heart failure. Proper implementation of vaccination plan and multidisciplinary acts are mandatory for maintaining such cases to reduce the mortality and morbidity. Furthermore, CHD are also at risk of vaccine adverse reaction and several blooddisseminated pathogens infections, and at risk of death if such events where to occur. Perception and Interpretation of the knowledge and experience of general pediatricians towards vaccination of patients with congenital heart diseases is a crucial element to understand, and to improve healthcare practice in Riyadh, Saudi Arabia...
