Pfizer-BioNTech announced Wednesday that preliminary preclinical data from mouse and macaque monkey models showed a strong immune response from its mRNA COVID-19 vaccine. 

According to the data, the vaccine candidate conferred “protective anti-viral effects” in rhesus macaque monkeys, as well as concomitant high neutralising antibody titers and a TH1-biased cellular response in both the monkeys and in mice.
