Cough is a common and commonly ignored symptom of lung disease. Cough is often perceived as difficult to quantify, frequently self-limiting, and non-specific. However, cough has a central role in the clinical detection of many lung diseases including tuberculosis (TB), which remains the leading infectious disease killer worldwide.

Background: We evaluated immunogenicity of SCB-2019, a subunit vaccine candidate containing a pre-fusion trimeric form of the SARS-CoV-2 spike (S)-protein adjuvanted with CpG-1018/alum.

Methods: The phase 2/3, double-blind, randomized SPECTRA trial was conducted in five countries in participants aged ≥ 18 years, either SARS-CoV-2-naïve or previously exposed. Participants were randomly assigned to receive two doses of SCB-2019 or placebo administered intramuscularly 21 days apart.

Article Synopsis
  • The study evaluated the safety and efficacy of the SCB-2019 COVID-19 vaccine in a large, double-blind, placebo-controlled trial involving over 30,000 adults across five countries.* -
  • Participants were randomly assigned to receive either the vaccine or a placebo, and the primary focus was on measuring vaccine effectiveness against COVID-19 and monitoring adverse effects.* -
  • Results showed that the vaccine had an overall efficacy of 67.2% against any severity of COVID-19, and 83.7% efficacy against moderate-to-severe cases, indicating its potential effectiveness in preventing the disease.*

Background: The absolute degree of protection from influenza vaccines in older adults has not been studied since 2001. This study aimed to show the clinical efficacy of an MF59-adjuvanted quadrivalent influenza vaccine (aQIV) in adults 65 years or older compared with adults not vaccinated to prevent influenza.

Methods: We did a randomised, stratified, observer-blind, controlled, multicentre, phase 3 study at 89 sites in 12 countries in 2016-17 northern hemisphere and 2017 southern hemisphere influenza seasons.
