Vaccine-Preventable Diseases and the Vaccines That Prevent Them

Why Vaccines Matter More Than Ever

Vaccines are one of the greatest public health achievements in modern history. Many diseases that once killed or disabled millions of people every year are now largely preventable thanks to immunization. Yet as vaccination rates decline in some communities, diseases that were nearly eliminated are making a comeback.

At MediOAK Pharmacy, we believe that informed patients make better health decisions. This guide walks you through the most common vaccine-preventable diseases and exactly which vaccines protect against them.

Influenza (Flu)

Influenza is a highly contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness and can lead to hospitalization or even death, particularly in young children, older adults, and individuals with weakened immune systems.

Pneumococcal Disease (Pneumonia)

Pneumococcal disease is caused by bacteria called Streptococcus pneumoniae. It can lead to pneumonia, meningitis, and bloodstream infections. Older adults and young children are most at risk, but anyone with a weakened immune system or chronic illness can be vulnerable.

Shingles (Herpes Zoster)

Shingles is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. It results in a painful rash and can lead to long-lasting nerve pain known as postherpetic neuralgia. Anyone who has had chickenpox can develop shingles later in life.

Measles, Mumps, and Rubella (MMR)

Measles, mumps, and rubella are viral infections that can cause serious complications including encephalitis, deafness, and birth defects. Although they were once common childhood illnesses, they are now largely preventable through vaccination.

Hepatitis B

Hepatitis B is a serious liver infection caused by the hepatitis B virus. It can become chronic and lead to liver failure, liver cancer, or cirrhosis. The virus is spread through contact with infectious body fluids, blood, or from mother to child during birth.

Varicella (Chickenpox)

Chickenpox is a highly contagious disease caused by the varicella-zoster virus. While it is often considered a mild illness in children, it can be severe in adults and in people with weakened immune systems, causing pneumonia and other serious complications.

Tetanus, Diphtheria, and Pertussis (TDAP)

Tetanus (lockjaw), diphtheria, and pertussis (whooping cough) are serious bacterial infections. Pertussis in particular can be life-threatening for newborns. Adults should receive a TDAP booster to help protect themselves and vulnerable infants they come into contact with.

Immigration Vaccines
