Vaccines and Immunization You can help protect yourself and others against seasonal flu and other vaccine-preventable diseases by getting immunized. Vaccines are some of the safest medical products. But, like any other medical product, there may be risks. Talk to your health care provider about the value of vaccines and their side effects. Vaccines to consider. Influenza (flu): People who are 6 months and older should get the flu vaccine (flu shot). Get the vaccine each year because flu virus can change from one year to the next. Pneumococcal: Older people and those with certain medical conditions are most susceptible to pneumonia.
