  author={Tam{\'a}s Ferenci and Bal{\'a}zs Sarkadi},
Background: Limited information is available on the effectiveness of the BBIBP-CorV (Sinopharm, Beijing CNBG) vaccine, especially in the elderly, despite the fact that it is approved in more than 50 countries. Methods: Virus neutralizing antibody titres, as a rapidly available but highly predictive surrogate marker, were measured after two doses of the BBIBP-CorV vaccine in 450 subjects. Results were analyzed in a multivariable model accounting for age, sex and time since the administration of…

Safety and Efficacy of the BNT162b2 mRNA Covid-19 Vaccine

A two-dose regimen of BNT162b2 conferred 95% protection against Covid-19 in persons 16 years of age or older and safety over a median of 2 months was similar to that of other viral vaccines.

Correlates of protection against symptomatic and asymptomatic SARS-CoV-2 infection

Correlates of protection can be used to bridge to new populations using validated assays and extrapolate efficacy estimates for new vaccines where large efficacy trials cannot be conducted.

Neutralizing antibody levels are highly predictive of immune protection from symptomatic SARS-CoV-2 infection.

It is shown that neutralization level is highly predictive of immune protection, and an evidence-based model of SARS-CoV-2 immune protection that will assist in developing vaccine strategies to control the future trajectory of the pandemic is provided.
