Immunizations: Staying Protected at Every Age
Why Immunizations Matter
Vaccines train the immune system to recognize and fight specific diseases before exposure occurs. They prevent serious illness, hospitalization, disability, and death, including certain cancers. Routine immunizations protect individuals and help maintain community (herd) immunity. Source 9
Recommended Vaccines by Age
Infants and children should follow CDC schedules to protect against 16 diseases starting at birth. Preteens and teens need catch-up doses plus Tdap, meningococcal, and HPV vaccines. Adults benefit from annual flu shots, COVID-19 boosters, shingles, pneumococcal, and travel vaccines. Seniors and high-risk groups require additional pneumococcal and shingles protection. Source 3
Vaccine Safety and Effectiveness
Extensive testing and ongoing monitoring confirm vaccines are safe and effective. Side effects are usually mild; serious reactions are extremely rare. Organizations such as CDC, WHO, AAP, and Immunize.org provide evidence-based guidance. Source 4
Where to Get Vaccinated
Major pharmacy chains like CVS and Walgreens offer convenient online scheduling for flu, COVID-19, and travel vaccines. Local health departments and pediatrician offices provide childhood and school-required immunizations. Medicare and most insurance plans cover recommended vaccines at little or no cost. Source 2
Catching Up After Missed Doses
The COVID-19 pandemic caused many children and adults to fall behind on routine shots. California and other states urge families to review records and schedule catch-up appointments promptly. School requirements and “Shots for School” resources help ensure compliance. Source 5
