Intranasal vaccine offers promise to block COVID-19 where it starts

Added: 09.11.2021 22:20 | 200 views | 0 comments

Research to create a COVID-19 vaccine which can be administered through the nose has taken a significant step forward. The pre-clinical animal trials of the intranasal vaccine showed a reduction in both the impact of the disease itself and transmission of the virus.

Scientists discover how dengue vaccine fails to protect against disease

Added: 09.11.2021 22:20 | 212 views | 0 comments

Researchers discovered that a small subpopulation of antibodies binding to unique sites on each serotype are linked to protection. The research provides important information for vaccine developers to consider when creating a dengue vaccine, which has long eluded scientists.

Streptococcus pneumoniae sticks to dying lung cells, worsening secondary infection following flu

Added: 09.11.2021 22:20 | 209 views | 0 comments

Researchers have found a further reason for the severity of dual infection by influenza and Streptococcus pneumonia -- a new virulence mechanism for a surface protein on the pneumonia-causing bacteria S. pneumoniae. This insight comes 30 years after discovery of that surface protein, called pneumococcal surface protein A. This mechanism had been missed in the past because it facilitates bacterial adherence only to dying lung epithelial cells, not to living cells.

New research suggests there may someday be a role for ibuprofen in providing older adults with lasting immunity against RSV, a virus commonly associated with infants and young kids that also rivals the flu as a dangerous wintertime infection for the elderly.

Will COVID-19 vaccines need to be adapted regularly?

Added: 07.11.2021 20:50 | 207 views | 0 comments

Influenza vaccines need to be evaluated every year to ensure they remain effective against new influenza viruses. Will the same apply to COVID-19 vaccines? Researchers compared the evolution of endemic 'common cold' coronaviruses with that of influenza viruses. The researchers predict that, while the pandemic is ongoing, vaccines will need to undergo regular updates. A few years into the post-pandemic period, however, vaccines are likely to remain effective for longer.

Combination therapy may provide significant protection against lethal influenza

Added: 07.11.2021 20:50 | 212 views | 0 comments

A significant proportion of hospitalized patients with influenza develop complications of acute respiratory distress syndrome. Investigators have found that treatment with an immune receptor blocker in combination with an antiviral agent markedly improves survival of mice infected with lethal influenza and reduces lung pathology in swine-influenza-infected piglets. Their research also provides insights into the optimal timing of treatment to prevent acute lung injury.
