Vaccination provides protection against illnesses caused by bacteria and viruses. A vaccine works by introducing a piece of the germ or a dead or weakened germ. This causes your body to recognize the germ as harmful. You create antibodies against the germ and generate memory cells so that your body will continue to recognize and fight that germ in the future.
Vaccination is an important component of both individual healthcare and public health safety. It can prevent you from getting a disease, or from getting very ill or dying of the disease if you do get it. Vaccination also reduces other community members’ exposure to disease. This result is called herd immunity. This outcome of mass vaccination is important for the safety of those who can’t be vaccinated (e.g., people with certain medical conditions or taking certain medications) or who have less well-developed immune systems (e.g., babies, the elderly).
Several vaccines are commonly recommended for adults, in addition to the lifetime vaccines most of us got as children.
Some recommended adult vaccines are seasonal, reformulated to protect from the prevailing strains of germs present each year. Those include:
COVID-19 vaccines are reformulated each year to match the latest germ variants. Get the new shot each year.
Influenza (flu) vaccines are also reformulated annually to protect against the coming season’s flu variants. Get this update in September or October.
To combat germs that do not generally change annually, consider the following:
Pneumococcal vaccine protects against three serious health threats: pneumonia, meningitis and bacteremia. Pneumonia is an infection of the lungs. Meningitis is inflammation of the membranes around the brain and spinal cord. Bacteremia is a blood infection that can cause sepsis. All three infections are caused by the same bacteria and can be life-threatening.
Respiratory syncytial virus (RSV) vaccine protects against a seasonal viral disease that usually causes only mild, cold-like symptoms. However, this disease can be more severe in infants and the elderly. Adults over age 75 (over age 50 if at high risk) should get this vaccination. Pregnant women should get this vaccination at 32-36 weeks to protect their newborn child.
The shingles (Zoster) vaccine protects against the exceedingly painful rash caused by the virus that caused chickenpox and re-emerged in your body. You will need two shots, 2-6 months apart.
The tetanus booster (Td vaccine) protects against both tetanus and diphtheria. Adults need a booster every ten years.
Talk with your healthcare provider about which vaccinations are appropriate for you.
