Respiratory delivered vaccines: Current status and perspectives in rational formulation design.

The respiratory tract is susceptible to various infections and can be affected by many serious diseases. Vaccination is one of the most promising ways that prevent infectious diseases and treatment of some diseases such as malignancy. Direct delivery of vaccines to the respiratory tract could mimic the natural process of infection and shorten the delivery path, therefore unique mucosal immunity at the first line might be induced and the efficiency of delivery can be high.

Whether Omicron exposures could overcome ancestral SARS-CoV-2 immune imprinting remains controversial. Here we analyzed B cell responses evoked by sequential Omicron infections in vaccinated and unvaccinated individuals. Plasma neutralizing antibody titers against ancestral SARS-CoV-2 and variants indicate that immune imprinting is not consistently induced by inactivated or recombinant protein vaccines.

Background: The rapid development and distribution of mRNA COVID-19 vaccines has been essential in containing the SARS-CoV-2 epidemic around the globe. For ongoing and future immunization campaigns globally, there is a need to evaluate the impact of population demographics such as age and sex, on vaccine efficacy and safety.
Methods: This systematic review (PROSPERO ID CRD42023328245) conducted according to PRISMA guidelines evaluates the impact of age and sex on the safety and efficacy of the mRNA COVID-19 vaccinations administrated in 15 studies that were chosen according to strict criteria.

The novel coronavirus that caused the epidemic and pandemic resulting in the acute respiratory illness known as coronavirus disease 2019 (COVID-19) has plagued the world. This is unlike other coronavirus outbreaks that have occurred in the past, such as Middle East respiratory syndrome (MERS) or severe acute respiratory syndrome (SARS). COVID-19 has spread more quickly and posed special challenges due to the lack of appropriate treatments and vaccines.

Pneumococcal disease (PD) caused by (Sp) is a global public health concern. Children younger than 5 years and elderly over 60 years, due to immature development of the immune system early in life or the gradual decline of immune function with age, are high-risk groups for pneumococcal infections, which makes the disease burden particularly serious and the situation of prevention and control grim. Vaccination is the most effective measure to prevent PD and reduce pneumococcal antimicrobial resistance.
