A recent study conducted by Public Health England found that the available vaccines were “highly effective” at preventing hospitalization after two doses.
Current COVID-19 vaccines present the spike protein in very different ways to the immune system, and two main categories have to be discerned. The first category consists of mRNA and adenoviral vector vaccines (herein referred to as genetic vaccines, sections: “Genetic vaccines—general, “mRNA...
According to WHO, diagnosis of COVID-19 infection at appropriate time after initial observation of symptoms play a crucial role in the control of pandemic. As of now, many commercial kits are available using nasal, nasopharyngeal and saliva samples. In India, multiple kits were available using s...
Mutations of the coronavirus could render current vaccines ineffective within a year, according to a survey of experts.
Lassa virus, the cause of deadly Lassa fever, is endemic in West Africa, where thousands of cases occur on an annual basis. Nigeria continues to report increasingly severe outbreaks of Lassa Fever each year and there are currently no approved vaccines or
pathway of the virus has led to the evasion of host immune response by emerging new mutants. Escape mutations could also ignite breakthrough infections and threaten global vaccination efforts. Nevertheless, current vaccines are still highly effective at preventing hospitalization and death by COVID-19...
COVID-19 vaccines are safe and recommended for all persons aged 12 years of age and older, even for those with prior SARS-CoV-2 infection. Immunologic data support the role of Food and Drug Administration (FDA)-authorized COVID-19 vaccines in offering protection against the known...
Even though effective vaccines against COVID-19 are now available, it is still unclear how widely accepted they will be by the public. Vaccine hesitancy has become a significant barrier to uptake (Salmon et al., 2015, Shetty, 2010), often fuelled by social media. The Mott Poll Report in ...
Lassa virus, the cause of deadly Lassa fever, is endemic in West Africa, where thousands of cases occur on an annual basis. Nigeria continues to report increasingly severe outbreaks of Lassa Fever each year and there are currently no approved vaccines or
The persistence of dynamic zero COVID-19 community transmission in Shanghai and other cities will overcome weak links in the immunological barrier in populations across the country. Fortunately, besides the available vaccines and heterologous vaccination approach, several new vaccines specifically targeting...
