Vaccines play a vital role in protecting patients from preventable diseases. At Orange County’s leading medical clinic for the LGBTQ+ community and others, we emphasize staying up-to-date on vaccinations as a key part of routine healthcare. Even with increased awareness, many adults still miss routine or booster doses. To address this challenge, we encourage everyone to regularly review their vaccination status and take proactive steps to protect their health and the community’s health.
Why Keeping Vaccinations Current Is Essential for Health
According to data from the Centers for Disease Control and Prevention, as of December 2025 only 15.6% of adults ages 18 and older had received the latest COVID-19 vaccine, while 40.2% had received the 2025–26 influenza vaccine. These trends reflect ongoing challenges in adult vaccination coverage that providers like Radiant Health Centers are actively working to address.
Many Serious Illnesses Are Preventable
Each year, diseases such as COVID-19, flu, pneumonia, Mpox and shingles cause severe illness, hospitalization or death among adults in Orange County. While treatment is available after infection, prevention through vaccination is often the safer and more effective approach. As a result, prevention has become a central focus of healthcare and public health efforts.
Vaccines Help Protect Adults Most at Risk
Some people face a higher risk from preventable diseases than others. Existing health conditions, lifestyle factors or increased exposure can raise the risk of serious illness, making timely immunization particularly important. Mpox is one example, where vaccination recommended as a two-dose series has played a key role in reducing spread among those at increased risk.
Vaccines Protect the Community
Vaccination is a shared responsibility that is most effective when uptake is high. As vaccination coverage increases, the risk of outbreaks in workplaces, social spaces and other shared settings decreases. For individuals living with serious health conditions, such as HIV or autoimmune diseases, certain vaccinations may not be possible. In these cases, collective responsibility and health awareness supports a healthy Orange County.
Booster Shots Help Restore Immunity
Staying up-to-date with boosters helps restore protection and improve immune response. Updated COVID-19 vaccines renew immunity against evolving variants, while an annual flu vaccine offers protection against commonly circulating strains. Routine boosters also help maintain protection against serious bacterial infections, with the Td or Tdap (tetanus, diphtheria and pertussis) booster recommended every 10 years.
Age and Health Conditions Can Increase Risk
As we age, immune responses can weaken and the risk of severe outcomes from preventable diseases increases. Similarly, individuals with chronic health conditions may face a higher risk of complications. Making use of Orange County’s vaccine and immunization services helps ensure adults stay up-to-date on recommended doses that can protect both themselves and immunocompromised loved ones.
