Background: Pakistan introduced Ten-valent pneumococcal-conjugate-vaccine PCV10 in 2012 as a 3 + 0 schedule without catch-up.
Methods: Children <2 years old in Matiari, Sindh provided nasopharyngeal swabs between 2014 and 2018, which were cultured for pneumococcus and serotyped through multiplex PCR at the Aga Khan University Hospital. Carriage rates over time for Vaccine-Type (VT) and Non-VT (NVT) serotypes were used to estimate direct, indirect, total and overall effects of vaccination. Regression analysis was used to determine factors associated with VT carriage.
Results: Pneumococcus was detected in 2370/3140 (75%). VT carriage decreased overall, 16.1-9.6% (p-trend <0.001); vaccinated (all 3 doses of PCV10 received) 11.3-8.1% (p-trend 0.031) and unvaccinated (no PCV10 dose received) 17.4-10.3% (p-trend 0.003) with a decline in serotypes 6B, 9V/9A and 19F. Immunization increased from 41.0% to 68.4% (p-trend 0.001). Direct effect of vaccine was 32.8% (95% CI 14.7-47.0%) and indirect effect 44.6%(95% CI 40.6-48.6%). Factors associated with decreased VT colonization were education 1-5 years (aOR 0.7, 95%CI 0.6-1.0), history of difficulty breathing (aOR 0.7, 95%CI 0.5-1.0), exposure to smoke (aOR 0.8, 95% CI 0.6-1.0), child fully immunized (aOR 0.7, 95%CI 0.5-1.0) and enrolled in 3rd (aOR 0.6, 95%CI 0.4-0.8) and 4th (aOR 0.6, 95%CI 0.5-0.9) year of the study whereas history of runny nose (aOR 1.5, 95% CI 1.2-1.9) was positively associated.
Conclusions: Decrease in VT pneumococcal carriage in vaccinated and unvaccinated children indicates herd immunity. Sustained increase in vaccine coverage and close long-term surveillance is warranted.

This is a short ballad about current health policy and practice regarding the Coronavirus. As vaccines are being administered, this poem points out that light is at the end of the tunnel. At the same time it urges caution, vigilance, masking and common sense. It praises science and scientists. It also calls for unity, cooperation and healing!

Disposable Lives: Covid-19, Vaccines, And The Uprising, Matiangai Sirleaf

Faculty Scholarship

Two French doctors appeared on television and publicly discussed potentially utilizing African subjects in experimental trials for a tuberculosis vaccine as an antidote to the novel coronavirus (COVID-19). Tedros Adhanom Ghebreyesus, the Director-General of the World Health Organization (WHO), denounced these kinds of racist remarks as a “hangover from ‘colonial mentality’” and maintained that “Africa can’t and won’t be a testing ground for any vaccine.” The fallout on social media was similarly swift, with Samuel Eto’o, a Cameroonian football legend, referring to the doctors as “[d]es assasins” and several others questioning the motives behind testing a vaccine on the African …

A Survey Of Primary Care Providers’ Strategies To Affect Influenza Vaccination Rates, Jennifer Moffett, Tracy Mitchell, Vera Simmons

MSN Research Projects

Influenza is a vaccine preventable disease that affects millions of Americans and causes thousands of deaths and billions in healthcare costs. Annual influenza vaccination is regarded by researchers and healthcare governing bodies as the most effective way to prevent contracting the flu. A large body of research exists supporting primary care providers as influential in regard to patients’ healthcare decision making. However, if strategies are consistently being implemented to affect influenza vaccination rates remains unclear. The purpose of this study was to identify strategies being implemented to affect influenza vaccination rates by asking two questions: 1. Do primary care providers …

The Intellectual Property Of Covid-19, Ana Santos Rutschman

All Faculty Scholarship

The response to COVID-19 is indissolubly tied to intellectual property. In an increasingly globalized world in which infectious disease pathogens travel faster and wider than before, the development of vaccines, treatments and other forms of medical technology has become an integral part of public health preparedness and response frameworks. The development of these technologies, and to a certain extent the allocation and distribution of resulting outputs, is informed by intellectual property regimes. These regimes influence the commitment of R&D resources, shape scientific collaborations and, in some cases, may condition the widespread availability of emerging technologies. As seen throughout this chapter, …

Covid-19 Vaccine-Associated Thrombosis With Thrombocytopenia Syndrome (Tts): A Systematic Review And Post Hoc Analysis, Muhammad Usman Hafeez, Maha Ikram, Zunaira Shafiq, Azza Sarfraz, Zouina Sarfraz, Vikash Jaiswal, Muzna Sarfraz, Ivan Chérrez-Ojeda

Department of Paediatrics and Child Health

Background: A new clinical syndrome has been recognized following the COVID-19 vaccine, termed thrombosis with thrombocytopenia syndrome (TTS). The following systematic review focuses on extrapolating thrombotic risk factors, clinical manifestations, and outcomes of patients diagnosed with TTS following the COVID-19 vaccine.
Methods: We utilized the World Health Organization's criteria for a confirmed and probable case of TTS following COVID-19 vaccination and conducted a systematic review and posthoc analysis using the PRISMA 2020 statement. Data analysis was conducted using SPSS V25 for factors associated with mortality, including age, gender, anti-PF4/heparin antibodies, platelet nadir, D-dimer peak, time to event diagnosis, arterial or …
