Impact of immunization with pneumococcal conjugated vaccines on the aplicability of the diagnostic criteria for specific pneumococcal antibody deficiency
Diagnostic criteria for specific antibody deficiency (SAD) were established before the incorporation of pneumococcal conjugate vaccines (PCV) in immunization schedules. We evaluated the effect of PCV immunization on the applicability of these criteria.

Results of Cross-Stakeholder Qualitative Study on the Potential Utility of a Hyperimmune Globulin for the Prophylaxis/Treatment for S. Pneumoniae Infection in Vulnerable Populations
Streptococcus pneumoniae accounts for 20% to 38% of nosocomial infection, contributing to high rates of hospitalization and mortality. Approximately half of the adult population are not vaccinated with approved and commercially available S. pneumoniae vaccines and remain vulnerable to contracting pneumonia, even post vaccination. We evaluated the potential clinical utility and level of reimbursement for an anti-pneumococcal polyclonal hyperimmune globulin ?for at-risk patients in hospital and outpatient settings.

Can AstraZeneca ’s Vaccine Prevent the Spread of COVID-19 Virus?
In a new—yet to be peer-reviewed—study, the pharmaceutical company AstraZeneca and its partners at the University of Oxford report that their COVID-19 shot may not only protect against disease but also help to prevent spread of the SARS-CoV-2 virus. The news was heralded by policy makers desperate to see a vaccine that can curb spread of the disease, but scientists have been a bit more cautious. If confirmed, the results would represent a breakthrough in the COVID-19 vaccine race. So far, the shots authorized or approved around the world have shown strong protection against moderate to severe disease, but haven...

Sex differences in antibody responses to the 23-valent pneumococcal polysaccharide vaccination
There are profound sex-based differences in both humoral and cellular immune responses to vaccination [1]. In general, adult females demonstrate higher antibody responses to bacterial and viral vaccines than men [2]. For instance, adult females vaccinated with half the dose of the trivalent inactivated influenza vaccine (TIV) produce similar humoral immune responses than adult males vaccinated with a full dose of the TIV [3]. Given that the 23-valent pneumococcal polysaccharide vaccine (PPSV23) is an important tool in our evaluation of the humoral immune response [4], we sought to determine if men and women have a signific...

An Enzyme-Linked ImmunoSpot Assay (ELISPOT) to Assess Pneumovax ® Response when on Intravenous Immunoglobulin
Testing for common variable immunodeficiency (CVID) requires evaluation of specific antibody responses to vaccines. Current practice of assessing pneumococcal serotype-specific IgG levels after Pneumovax ® (P23) has several limitations and is not accurate for patients already on immunoglobulin replacement. In contrast, the Enzyme-Linked ImmunoSpot (ELISPOT) assay can be interpreted in patients on immunoglobulin replacement as ex vivo measurement of specific antibody secreting cells (ASC).

An enzyme-linked immunospot assay to evaluate Pneumovax response when on intravenous immunoglobulin
Testing for common variable immunodeficiency (CVID) requires evaluation of specific antibody responses to vaccines. Current practice of evaluating pneumococcal serotype-specific immunoglobulin (Ig)G levels after Pneumovax (P23) has several limitations and is not accurate for patients already on immunoglobulin replacement. In contrast, the enzyme-linked immunospot (ELISPOT) assay can be interpreted in patients on immunoglobulin replacement as ex vivo measurement of specific antibody-secreting cells (ASCs).

Diagnostic Vaccination in Clinical Practice
Testing the antibody response to vaccination (diagnostic vaccination) is crucial in the clinical evaluation of primary immunodeficiency diseases. Guidelines from the American Academy of Allergy, Asthma & Immunology (AAAAI) provide detailed recommendations for diagnostic vaccination with pure pneumococcal polysaccharide vaccines (PPV). However, the degree of compliance with these guidelines and the utility of the guidelines in actual practice are undescribed. To address this, we systematically evaluated diagnostic vaccination in adult patients with suspected primary immunodeficiency diseases in a single tertiary center ...

M174 haemophilus influenzae type b meningitis – a case of vaccine failure
Haemophilus influenzae is a pleomorphic gram-negative bacteria commonly found within the respiratory tract. Haemophilus influenzae serotype b (Hib) is a typeable (encapsulated) strain known to cause invasive disease. Hib polysaccharide-protein conjugate vaccines stimulate a highly immunogenic T-cell dependent response which has dramatically decreased the incidence of invasive disease. Here we present a case of Hib meningitis resulting in sensorineural hearing loss in an immunized infant, presumed to be secondary to vaccine failure.

Pneumococcal Vaccinations In Young Adults With HIV
CDC guidelines recommend pneumococcal conjugate vaccine (PCV) followed by polysaccharide vaccine (PPSV23) for adult HIV+ patients. This assumes immune compromise. Most young adults with HIV have received PCV as infants.

Descriptive Study of IgG Protection for PCV13 Serotypes in Immunodeficient Patients on IVIG
Intravenous immunoglobulin (IVIG) therapy provides IgG antibodies from a donor pool to immunodeficient patients. Since PCV13 vaccine was introduced in 2010, adult donors may not have received the vaccine, thus not having PCV13 specific antibodies to donate. This descriptive analysis will highlight how pneumococcal vaccination affects Streptococcus pneumoniae protection, hospitalization rates, and associated comorbidities in immunodeficient individuals.
