A therapeutic vaccine of uncertain efficacy was developed shortly after the discovery of the causative agent, Bordetella pertussis , in However, it was not until that an effective preventive vaccine was designed.

Thanks to improved cultivation methods, Pearl Kendrick, Grace Eldering and Loney Gordon developed a highly effective, whole-cell inactivated vaccine wP. In the late s the pertussis vaccine was combined with diphtheria and tetanus toxoids to become DTP and was widely adopted shortly afterwards. By the early s, the introduction of pertussis vaccines was associated with a large decline in cases, with incidence of whooping cough in the USA decreasing fold.

Unfortunately, as the risks from whooping cough decreased markedly, attention shifted from the risk of disease to fear of vaccine side effects. The whole-cell pertussis vaccine causes rare but significant side effects.

In addition to the usual local inflammatory effects and fever associated with many vaccines, whole-cell pertussis vaccines sometimes trigger prolonged crying and febrile convulsions and, very rarely, hypotonic—hyporesponsive episodes.

Claims of causal links to various neurological issues were also made. However, those neurological side effects were observed in very small numbers of children and were later demonstrated to be unrelated to the vaccine, but the reputational damage was done.

The whole-cell pertussis vaccine was blamed for causing various intellectual and physical disabilities, including in a TV documentary. Thousands of parents refused to vaccinate their children, and a flood of personal injury lawsuits forced many companies to stop producing vaccines. Three countries, Sweden, the UK and Japan, interrupted or decreased pertussis vaccination. Meanwhile, in response to concern about the side effects, Yuji Sato was working on an acellular pertussis vaccine.

Influenza vaccines, available since the s, are now recommended for most adults. Vaccines like MMR and chickenpox are recommended for adults who have not had the diseases, and vaccines including hepatitis A, hepatitis B, pneumococcus, and meningococcus are recommended for sub-groups of the adult population. The HPV vaccine became available in In , the license was expanded to include people up to 45 years of age.

Two doses of this vaccine, separated by two to six months, are recommended for people 50 years and older. In , Zostavax was no longer available. Most adults were recommended to get this vaccine, but limited supplies required adults to be assigned to eligibility groups in order to protect those most at risk first. Unlike childhood vaccines, which are often required for entrance to schools, adult vaccines are typically not mandated. However, people with certain occupations may be required to get vaccinated as a condition of employment.

Most often, this occurs in the military and in healthcare-related occupations, but other industries may also require employment-based vaccinations. Limited requirements and a lack of preventive healthcare by most adults have led to low levels of vaccine use by adults.

Vaccine History: Developments by Year. Contact Us Online. Used in different age groups of children, the following combinations of vaccines are now available: Diphtheria, tetanus and acellular pertussis Diphtheria, tetanus, acellular pertussis, and inactivated polio Diphtheria, tetanus, acellular pertussis, inactivated polio and hepatitis B Diphtheria, tetanus, acellular pertussis, inactivated polio and Haemophilus influenzae type b Diphtheria, tetanus, acellular pertussis, inactivated polio, Haemophilus influenzae type b, and hepatitis B Measles, mumps and rubella Measles, mumps, rubella, and varicella Hepatitis A and hepatitis B only for those 18 years of age and older Vaccines for Adolescents: A new generation of vaccines Adolescents, like adults, were recommended to get tetanus boosters every 10 years; most requiring their first booster dose around age The first formal adult immunization schedule was published in and is updated annually.

The two scientists were on a mission to collect bacteria in the wild: one by one, they visited families ravaged by whooping cough, the deadliest childhood disease of their time. By the dim light of kerosene lamps they asked sick children to cough onto each plate, dimpling the agar gel with tiny specks of the bacteria Bordetella pertussis. Developed at a time when scientific funding was so scarce that lab mice were considered a luxury, the vaccine would go on to prevent thousands of children each year from succumbing to the disease.

In the s, Kendrick and Eldering's lab also developed the vaccine that most people receive today, called DTP, that protects against diphtheria and tetanus as well as whooping cough, alongside an African-American female chemist named Loney Gordon. This became a staple early-life vaccine, multiplying the survival rate of children in the United States as it spread across the country. Back when Eldering and Kendrick began working on their vaccine in the s, an estimated 6, kids in the United States were dying from whooping cough, or pertussis, each year —more than from diphtheria, scarlet fever, tuberculosis or polio.

In a vicious cycle, the cough spreads the contagion to others, and is so powerful that it can induce shaken baby syndrome. Babies who get it have a high chance of dying. Pearl Kendrick, seen here in , was a bacteriologist with the Michigan Department of Health who developed the first successful vaccine for whooping cough in the s with Grace Eldering. As whooping cough ravaged the Grand Rapids area, Kendrick and Eldering worked around the clock to battle the highly contagious disease.

They knocked on doors, analyzed samples, and later recruited locals for field trials of the vaccine. Incredibly, the original s vaccine work began as a side project for Kendrick and Eldering, who both worked in a laboratory at the Michigan Department of Health.

The scientists were motivated by personal experience. Both women had survived whooping cough as children Kendrick in New York, Eldering in Montana and knew firsthand how painful the disease was.
