Vaccination Practices in Japan: What Vaccines Did Japan Give Children in the 70s?

by

In the 1970s, Japan provided children with the live attenuated measles vaccine. By the mid-1980s, vaccines for diphtheria, tetanus, pertussis, measles, mumps, rubella, and polio were also given. The BCG vaccine was administered at age six, and influenza vaccination was mandatory for schoolchildren during this time.

Japan also provided vaccinations against polio and tuberculosis. The oral polio vaccine was widely administered to protect children from poliomyelitis, a disease that can lead to paralysis. Bacillus Calmette-Guérin (BCG) vaccine for tuberculosis was also part of the routine immunization program. The country encouraged high vaccination coverage to create herd immunity, which protects those who cannot be vaccinated.

These vaccination practices laid a strong foundation for immunization efforts in later years. Japan’s approach emphasized accessibility and community health. This vaccination strategy not only aimed to protect individual children but also to promote population health overall.

In the next section, we will explore the evolution of vaccination policies in Japan, particularly how they adapted to emerging diseases and international public health guidelines.

What Vaccines Were Most Commonly Given to Children in Japan During the 70s?

Japan commonly administered several vaccines to children during the 1970s. The main vaccines included the following:

  1. Diphtheria, Tetanus, Pertussis (DPT) Vaccine
  2. Oral Poliovirus Vaccine (OPV)
  3. Measles Vaccine
  4. Rubella Vaccine
  5. BCG (Bacillus Calmette-Guérin) Vaccine

These vaccines aimed to protect children from serious infectious diseases. In Japan during the 1970s, public health policies emphasized immunization to reduce childhood morbidity and mortality.

1. Diphtheria, Tetanus, Pertussis (DPT) Vaccine:

The DPT vaccine prevents three serious diseases: diphtheria, tetanus, and pertussis (whooping cough). Diphtheria is a bacterial infection affecting the throat and can cause severe respiratory problems. Tetanus is a life-threatening disease affecting the nervous system, while pertussis is highly contagious and can lead to serious complications in infants. In the 1970s, Japan made this vaccination mandatory for children, with widespread acceptance leading to lower incidence rates. According to a study by the World Health Organization in 1977, the DPT vaccine contributed significantly to the decline of these diseases in Japan.

2. Oral Poliovirus Vaccine (OPV):

The OPV protects against poliomyelitis, a viral disease that can cause paralysis. In the 1970s, Japan used the trivalent OPV, which contains live attenuated viruses for all three types of poliovirus. The introduction of the OPV played a crucial role in eliminating polio outbreaks in Japan. A report from the Ministry of Health, Labour and Welfare in 1978 indicated that Japan had successfully reduced polio cases significantly following the vaccination campaign.

3. Measles Vaccine:

The measles vaccine protects against a highly contagious viral infection that causes severe complications, including pneumonia and encephalitis. Japan introduced the measles vaccine in the early 1970s. A national vaccination program was implemented to reach a high coverage rate. By the late 1970s, the incidence of measles decreased sharply. Data from a 1979 study by the Japanese Preventive Medicine Association noted a steep decline in measles cases after the vaccination program commenced.

4. Rubella Vaccine:

The rubella vaccine prevents rubella, a viral infection that can cause serious birth defects if contracted during pregnancy. Vaccination campaigns began in the early 1970s as part of the measles-rubella (MR) initiative. The focus on vaccinating children, especially young girls, aimed to prevent congenital rubella syndrome. A study conducted by the Japan Pediatric Society in 1977 showed that vaccination reduced rubella cases significantly, leading to fewer congenital cases.

5. BCG (Bacillus Calmette-Guérin) Vaccine:

The BCG vaccine protects against tuberculosis (TB), a serious bacterial infection that primarily affects the lungs. Japan has historically prioritized TB prevention due to the disease’s prevalence. The BCG vaccination program targeted infants and young children, as early immunization showed effectiveness. Research published in the Japanese Journal of Infectious Diseases in 1975 confirmed that BCG vaccination dramatically reduced TB infection rates in vaccinated populations.

In summary, Japan’s vaccination efforts in the 1970s focused on ridding the population of particular infectious diseases. The adoption of these key vaccines demonstrated significant public health advancements during that period.

What Were the Key Objectives of Vaccination Programs for Children in Japan in the 70s?

The key objectives of vaccination programs for children in Japan during the 1970s focused on disease prevention, community health, and overall societal well-being.

  6. Tetanus
  7. Poliomyelitis

The vaccination program was a response to the public health needs of the time and aimed to reduce the incidence of these diseases among children.

  1. Measles: The measles vaccine targeted this highly contagious viral infection. Measles is characterized by high fever, cough, runny nose, and a distinctive rash. In 1970, approximately 5 million cases of measles occurred annually in the U.S. alone, prompting widespread vaccination efforts globally, including Japan. The introduction of the measles vaccine in Japan in the early 1970s significantly reduced incidence rates and protected children from severe complications.

  2. Rubella: Rubella, also known as German measles, is a viral infection that can cause serious birth defects if contracted during pregnancy. The rubella vaccine was introduced to prevent outbreaks and reduce congenital rubella syndrome cases. Japan recognized the importance of vaccinating children to achieve herd immunity, which ultimately contributed to major declines in rubella cases by the late 1970s.

  3. Mumps: The mumps vaccine sought to eliminate this viral illness that causes swollen salivary glands. Mumps can lead to complications such as meningitis and orchitis. Vaccination programs in the 1970s resulted in decreased mumps incidence, enhancing public health and reducing hospitalizations.

  4. Diphtheria: Diphtheria is a bacterial infection affecting the throat and nose, leading to breathing difficulties. The diphtheria vaccine was part of a combined vaccination schedule, including tetanus and pertussis. The introduction of this vaccine played a crucial role in preventing outbreaks, as Japan was still reporting cases prior to widespread immunization efforts.

  5. Pertussis (Whooping Cough): Pertussis is a highly contagious bacterial infection characterized by severe coughing fits. The vaccine effectively reduced the occurrence of pertussis-related hospitalizations. By the mid-1970s, Japan reported fewer cases, demonstrating the efficacy of the vaccination program.

  6. Tetanus: The tetanus vaccine protects against a potentially fatal infection caused by bacteria found in soil and dust. The vaccine’s implementation helped to reduce tetanus cases significantly. Japan’s focus on immunization contributed to the protection of children from this life-threatening disease.

  7. Poliomyelitis: The poliovirus can cause paralysis and is preventable through vaccination. The oral poliovirus vaccine was used in Japan to control polio outbreaks. By the mid-1970s, Japan successfully reduced polio cases, showcasing the success of its vaccination initiatives.

Overall, the concerted efforts to vaccinate children against these infectious diseases in Japan during the 1970s led to significant improvements in public health outcomes.
