San Francisco Oakland San Jose, CA, August 27, 2026 —

San Francisco health officials have issued a reminder to at-risk residents regarding the Jynneos mpox vaccine, expanding recommendations as the city prepares for its annual fall festival season. This proactive measure comes as popular events such as the Folsom Street Fair and the Portola Music Festival approach.

The advisory aims to increase awareness and vaccination rates for mpox (formerly known as monkeypox). Health officials are particularly concerned about the ongoing mpox cases and the potential circulation of a more severe strain, identified as clade I. This strain has been potentially linked to international travel, prompting additional caution.

In response to these concerns, health authorities are advising individuals who have traveled to areas where mpox cases are prevalent or who have had close contact with individuals traveling from or residing in such areas, to consider vaccination. The Jynneos vaccine is available and recommended for individuals identified as at higher risk.

The upcoming fall festival season, known for drawing large crowds, presents an increased opportunity for transmission if preventative measures are not observed. Officials emphasize the importance of vaccination as a key tool in preventing outbreaks and protecting public health.

Details regarding specific dates for the festival season and the exact nature of the expanded recommendations, beyond the focus on travelers and their close contacts, were not immediately provided. Residents are encouraged to consult with their healthcare providers or visit the San Francisco Department of Public Health’s official channels for the most current information and guidance on mpox vaccination eligibility and availability.
