Preventing a Hepatitis A Outbreak in San Francisco
San Diego, Santa Cruz, and Los Angeles counties are currently having outbreaks of hepatitis A infection, primarily among homeless persons and/or users of injection and non-injection drugs. Cases with the same strain of hepatitis A infection have begun to appear in other California counties. There have been no cases of hepatitis A this year among these same populations in San Francisco.
Health care facilities and providers should offer hepatitis A vaccine to all at-risk patients who are not known to be immune or to have completed a series with hepatitis A or hepatitis A/B vaccine. Screening for serological immunity prior to vaccination is not necessary. Vaccination consists of 2 doses of hepatitis A vaccine given at least 6 months apart. The first dose rapidly protects about 98 out of 100 persons and the second dose ensures lifetime protection. A combination hepatitis A/B vaccine is also available; at least 3 doses are required; the first dose is not as protective but this difference disappears once the full series is completed.
Persons seeking hepatitis A vaccination should visit their regular provider, or visit our SF Hepatitis A Outbreak Prevention page or dial 311 to learn the location and hours of SF clinics where they are welcome to drop in and receive free hepatitis A vaccine.

Pregnant? Get Vaccinated to Protect Your Baby from Pertussis
Pertussis (Whooping Cough) is an easily spread infectious disease. It can cause coughing fits that make it hard to breathe. Young babies can get very sick, very fast if they get pertussis. Vaccination is the best way to prevent pertussis. The pertussis vaccine for adolescents and adults is called Tdap.
- Pregnant women need a Tdap shot during their third trimester of pregnancy (27 – 36 weeks), even if they were vaccinated before pregnancy.
- When the mother gets a Tdap vaccine during pregnancy, it gives the baby immunity (protection) from whooping cough until the baby can get its own shots .
- Women need a Tdap shot each time they are pregnant.
In addition to the pregnancy Tdap dose, babies, adolescents, and adults are all recommended to get pertussis vaccine. Protection from vaccination decreases over time. Talk to your doctor to make sure you and your family are up-to-date on your vaccines. For more information, visit our Pertussis page.
