Public Health encourages families to stay up to date on recommended vaccinations to protect children and the community from serious diseases. 

Vaccination remains one of the most effective ways to protect families from serious infectious diseases. San Bernardino County Public Health encourages residents to stay informed about recommended vaccines for newborns, children and adults, and to stay up to date on routine immunizations that prevent severe illnesses, hospitalizations and deaths.

An example during this holiday season is getting your seasonal flu vaccine,which remains a critical tool for reducing complications, including deaths from influenza. Flu can lead to severe outcomes, especially for young children, older adults, those who are pregnant and individuals with underlying medical conditions. Getting vaccinated helps prevent serious illness and reduces the risk of hospitalization during periods of increased community transmission.

Recent information shared through the West Coast Health Alliance and partner health departments has underscored the importance of clear, accurate communication on vaccine safety, including autism and hepatitis B.

“Clear, reliable information helps families make informed decisions,” said San Bernardino County Health Officer Dr. Sharon Wang.

Hepatitis B vaccination is one of the strongest public health success stories in reducing — and in many regions, virtually eliminating — this chronic disease. The hepatitis B vaccine has been tested extensively for safety and efficacy, and when administered within 24 hours of birth it is highly effective in preventing newborn infection.

“They save lives and prevent long-term complications and deaths. Ensuring newborns, children and adults are protected through timely vaccination is one of the most important steps we can take to support community health,” said Dr. Wang.

Hepatitis B: Why early protection matters

Hepatitis B is a highly infectious virus that can lead to chronic liver disease, liver failure and liver cancer. It spreads easily, even without visible blood or body fluids, and can survive on surfaces for up to one week.

Infants are particularly vulnerable:

  • Up to 90% of infants infected at birth develop chronic infection
  • About 25% of infected children may die prematurely from liver-related illness

To provide strong early protection, health experts recommend:

  • A hepatitis B birth dose within 24 hours of delivery
  • Completion of the full vaccine series for long-lasting immunity

This early dose is essential because many people with hepatitis B do not know they are infected, and household exposure can happen without warning.

Vaccines are safe and well-studied

Vaccines used in the United States undergo rigorous testing and continuous safety monitoring. National medical organizations, including the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists, and the Infectious Diseases Society of America, support routine vaccination across all age groups.

Staying protected: What families can do

Parents and caregivers are encouraged to:

  • Talk with their health care provider about recommended vaccines
  • Ensure newborns receive the hepatitis B birth dose
  • Keep children and adults up to date with routine immunizations
  • Seek information from trusted medical sources and licensed providers

If you do not have a primary care provider, county health centers offer vaccination services. To schedule an appointment, call 800-722-4777.

Residents may also find flu and other recommended vaccines through myturn.ca.gov.
