Researchers at Yerkes National Primate Research Center, Emory University, have developed a COVID-19 vaccine that has proven safe and effective in mice and monkeys.

Results from this National Institute of Allergy and Infectious Diseases (NIAID)-funded study are published online today in Immunity.

The Emory MVA COVID-19 vaccine approaches inducing protective immunity via modified vaccinia Ankara (MVA), a harmless version of a poxvirus that is well-known for its use in HIV/AIDS vaccines.

Like the Moderna and Pfizer COVID-19 vaccines, the Emory MVA COVID-19 vaccine induces strong neutralizing antibodies, which support the immune system’s ability to fight infections.

The Emory MVA COVID-19 takes protection several steps further, starting with inducing killer CD8 T cells in addition to the neutralizing antibodies, providing a multi-pronged approach to halting SAR-COV-2. In addition, the Emory researchers say the vaccine is easily adaptable to address disease variants, can be used in combination with existing vaccines to improve their ability to combat variants and has the potential to be equally effective with a single dose.
