The U.S. Centers for Disease Control and Prevention (CDC) Technical Report issued on March 17, 2023, stated that despite the geographic spread of highly pathogenic avian influenza (HPAI) A(H5N1) viruses, only a small number of 'bird flu' cases in people have been identified.

The CDC stated all reported human cases since 2022 have been associated with poultry exposures.

And no bird flu cases of human-to-human transmission have been identified, says the CDC.

However, because of the potential for influenza viruses to evolve rapidly, continued sporadic human infections are anticipated.

To date, more than 6,300 people in 52 jurisdictions have been monitored since 2022, and only one human case in Colorado has been identified.

However, there has been an upsurge in various mammals dying from bird flu in Canada and the U.S. during 2023.

The CDC presented some good news regarding bird flu vaccines.

An H5 candidate vaccine virus (CVV) produced by CDC is nearly identical or, in many samples, identical to the hemagglutinin (HA) protein of recently detected clade HPAI A(H5N1) viruses in birds and mammals and could be used to produce a vaccine for people. 

This H5 CVV is available and has been shared with vaccine manufacturers.

One manufacturer, CSL Seqirus Inc., has already produced a U.S. FDA-approved vaccine, Audenz™.

Audenz is a monovalent, adjuvanted, cell-based inactivated influenza (H5N1) subunit vaccine designed to protect people from bird flu.
