Here's the press release for Pfizer/BioNTech.
US results were release a week or two ago, and discussed here. This is the German Phase 1/2 study, with 60 participants. In addition to similar antibody results as the US study, this study also showed strong T-cell responses.
From the link:
The data further demonstrated the ability of BNT162b1 to elicit high SARS-CoV-2 neutralizing titers
BNT162b1 elicited strong CD4+ and CD8+ T cell responses against SARS-CoV-2- receptor binding domain (RBD), compared to baseline
The RBD-specific, interferon-g+, IL-2+, CD8+ T cells elicited by BNT162b1 in immunized participants indicate a strong potential for cell mediated anti-viral activity
T cell cytokine profile shows vaccine elicited T cells exhibit a Th1 phenotype, which is associated with antiviral properties
BNT162b1 induced antibodies had broadly neutralizing activity in pseudovirus neutralization assays across a panel of sixteen SARS-CoV-2 RBD variants identified in published SARS-CoV-2 sequences and against the newly dominant D614G strain
Robust specific antibody and T cell responses, (both of which are considered by experts as key to a vaccine ensuring protection against disease) elicited by the BNT162b1 mRNA vaccine against RBD suggest a potential for multiple beneficial protective mechanisms against COVID-19
Local reactions and systemic events after immunization with BNT162b1 were dose-dependent, generally mild to moderate and transient, with occasional severe adverse events (Grade 3, e.g. flu-like symptoms and injection site reactions) that resolved spontaneously or could be managed with simple measures - no serious adverse events were reported
