Vaccine-Preventable Diseases

Vaccine-preventable diseases are those infectious diseases that can be prevented through vaccination. Vaccination is the process of administering a vaccine, which is a weakened or inactive form of a pathogen that triggers an immune response in the body, without causing the disease. The immune response results in the production of antibodies that provide immunity to the disease. This immunity protects individuals from contracting the disease and also prevents the spread of the disease to others.

There are many vaccine-preventable diseases, including measles, polio, diphtheria, tetanus, pertussis, hepatitis B, and influenza. In this article, we will discuss these diseases, including their symptoms, when they were first discovered, their treatment, and precautions that can be taken to prevent their spread.

Measles:

Measles is a highly contagious viral disease that is spread through respiratory droplets. Symptoms include fever, cough, runny nose, red eyes, and a rash that starts on the face and spreads down the body. Measles was first identified in 1757, and a vaccine was first introduced in 1963. The vaccine is given in two doses, and it is recommended that children receive the first dose at 12 to 15 months of age and the second dose at 4 to 6 years of age. There is no specific treatment for measles, and most people recover within a few weeks. However, complications can occur, including pneumonia, encephalitis, and death. Precautions that can be taken to prevent the spread of measles include getting vaccinated, practicing good hygiene, and avoiding contact with individuals who are sick.

Polio:

Polio is a viral disease that is spread through contaminated food or water. Symptoms include fever, fatigue, headache, vomiting, and paralysis. Polio was first identified in 1789, and a vaccine was first introduced in 1955. The vaccine is given in four doses, and it is recommended that children receive the first dose at 2 months of age and the last dose at 6 years of age. There is no cure for polio, and treatment focuses on relieving symptoms and preventing complications. Precautions that can be taken to prevent the spread of polio include getting vaccinated, practicing good hygiene, and avoiding contact with individuals who are sick.

Diphtheria:

Diphtheria is a bacterial disease that is spread through respiratory droplets. Symptoms include sore throat, fever, and a thick gray coating on the back of the throat. Diphtheria was first identified in 1826, and a vaccine was first introduced in 1923. The vaccine is given in three doses, and it is recommended that children receive the first dose at 2 months of age and the last dose at 6 years of age. Treatment for diphtheria includes antibiotics and antitoxin. Precautions that can be taken to prevent the spread of diphtheria include getting vaccinated, practicing good hygiene, and avoiding contact with individuals who are sick.

Tetanus:

Tetanus is a bacterial disease that is caused by a toxin produced by the bacterium Clostridium tetani. The toxin affects the nervous system and can cause muscle stiffness and spasms. Tetanus was first identified in 1884, and a vaccine was first introduced in 1924. The vaccine is given in three doses, and it is recommended that children receive the first dose at 2 months of age and the last dose at 6 years of age. Treatment for tetanus includes antitoxin and antibiotics. Precautions that can be taken to prevent the spread of tetanus include getting vaccinated, practicing good hygiene, and avoiding contact with soil or other materials that may contain the bacteria.

Pertussis (also known as whooping cough):

Pertussis is a bacterial disease that is spread through respiratory droplets. It is characterized by severe coughing fits that can last for several weeks. Pertussis was first identified in the 16th century, and a vaccine was first introduced in the 1940s. The vaccine is given in five doses, and it is recommended that children receive the first dose at 2 months of age and the last dose at 4 to 6 years of age. Treatment for pertussis includes antibiotics and supportive care. Precautions that can be taken to prevent the spread of pertussis include getting vaccinated, practicing good hygiene, and avoiding contact with individuals who are sick.

Hepatitis B:

Hepatitis B is a viral disease that is spread through contact with infected blood or bodily fluids. Symptoms include fatigue, fever, jaundice, and abdominal pain. Hepatitis B was first identified in the 1960s, and a vaccine was first introduced in 1982. The vaccine is given in three doses, and it is recommended that children receive the first dose at birth and the last dose at 6 to 18 months of age. There is no cure for hepatitis B, and treatment focuses on managing symptoms and preventing complications. Precautions that can be taken to prevent the spread of hepatitis B include getting vaccinated, practicing safe sex, and avoiding contact with infected blood or bodily fluids.

Influenza:

Influenza (also known as the flu) is a viral disease that is spread through respiratory droplets. Symptoms include fever, cough, sore throat, muscle aches, and fatigue. Influenza was first identified in the 1930s, and a vaccine was first introduced in the 1940s. The vaccine is updated annually to target the specific strains of the virus that are circulating. It is recommended that everyone over the age of 6 months receive the vaccine annually. Treatment for influenza includes antiviral medications and supportive care. Precautions that can be taken to prevent the spread of influenza include getting vaccinated, practicing good hygiene, and avoiding contact with individuals who are sick.

In conclusion, vaccine-preventable diseases are a significant public health concern that can cause serious illness, disability, and death. Vaccination is the most effective way to prevent these diseases and protect individuals and communities from their spread. It is essential that individuals receive the recommended vaccines according to their age and health status, and that public health measures are implemented to promote vaccination and prevent outbreaks.
