A and B should be vaccinated annually. This includes those with chronic heart and respiratory conditions, cancer, kidney disease, diabetes, anemia, or conditions that alter immunity. Influenza vaccine is also advised for those over 65, and for healthy younger adults who work in close contact with persons at high risk. Individuals who are sensitive to eggs should not be given influenza vaccine. Patients with certain chronic conditions are at risk of developing pneumococcal infections, principally pneumonia.
Immunization consists of a single dose of vaccine.
Booster doses should not be given nor should the vaccine be given during pregnancy. For that reason, women of childbearing age who have never been vaccinated against rubella and who are antibody negative by testing should receive a single dose of vaccine. Pregnancy must be avoided for 3 months following injection, and the vaccine should never be taken by a pregnant woman. Hepatitis B Vaccine. Health care workers, physicians, dentists, and others who come in contact with contaminated needles are at risk of getting hepatitis B, a viral infection that affects the liver.
