Pertussis, a highly contagious disease of the respiratory tract, is caused by exposure to bacteria (Bordetella pertussis) found in the mouth, nose and throat of an infected person. Pertussis is primarily spread by direct contact with discharge from the nose or throat of infected individuals. Classic - or severe pertussis - as defined by the World Health Organization, consists of at least 21 days of cough illness (with the cough coming in spasms or paroxysms), associated whoops or post-cough vomiting, and laboratory confirmation. Despite widespread vaccination, reports of pertussis continue to rise in the U.S. At particular risk are newborns and babies who have not yet been fully vaccinated against pertussis, who are more likely to have severe pertussis, and who face the possibility of serious complications and death. Over the last decade, 80% of pertussis deaths have occurred in infants under 6 months of age.
The Journal of the American Medical Association (JAMA) has announced that a study to be published in the June 22/29 issue found that a new vaccine against whooping cough is effective in teens and adults, carriers of the contagious respiratory disease so dangerous to infants.
A comprehensive system of vaccine development in the U.S. resulted in a reduction of 87 to more than 99 percent in illness from ten vaccine-preventable diseases during the twentieth century. These dramatic successes should not be taken for granted, however, as the vaccine system now faces numerous challenges in manufacturing and development, according to a review article in the May/June issue of Health Affairs.
Recent shortages of vaccines, most recently the flu vaccine during the past winter, are not short-term glitches--they reflect long-term problems in the vaccine industry. A variety of social, legal and economic forces have caused pharmaceutical companies to withdraw their commitment to vaccines, according to pediatrician and vaccine expert Paul A. Offit, M.D., chief of Infectious Diseases at The Children's Hospital of Philadelphia.
GlaxoSmithKline today announced that its booster vaccine, Boostrix received approval from the United States (U.S.) Food and Drug Administration (FDA).
The latest comeback in the health arena is whooping cough and experts are sufficiently concerned for the US government to approve the first whooping cough booster shot meant just for adolescents. The shot will be added to a booster shot against two other diseases, tetanus and diphtheria, that children already get sometime between ages 10 and 18.
In recognition of National Infant Immunization Week (April 24, 2005 through April 30, 2005), the Nassau County Department of Health urges all parents to ensure that their infants and toddlers are fully protected from the following vaccine preventable diseases: diphtheria, tetanus, pertussis (whooping cough), poliomyelitis, measles, mumps, rubella, hepatitis B, haemophilus influenza (meningitis), varicella (chickenpox), pneumococcal disease and influenza.
Global health leaders today presented new research showing that vaccinating infants against Streptococcus pneumoniae -- a bacterium that causes deadly pneumonia, meningitis and sepsis -- could substantially reduce death and serious illness among children in the developing world. If used widely, a pneumococcal conjugate vaccine could prevent hundreds of thousands of child deaths each year.
A vaccine against pneumonia and invasive pneumococcal disease, a severe form of bacterial infection, can substantially reduce hospital admissions and improve the survival of children in developing countries, concludes a trial published in this week’s issue of The Lancet.
The U.S. Food and Drug Administration (FDA) is recommending the development of a vaccine to prevent the occurrence of pertussis (Whooping Cough) in adolescents.
Approximately one-third of U.S. children were undervaccinated for more than six months and one-fourth experienced delays in receiving many of the recommended vaccinations during their first 24 months of life, according to a study in the current issue of JAMA.
As global health leaders struggle to meet the United Nations goal of reducing mortality among the world's poorest children, vaccines are attracting more and more attention. The purchase of the vaccine is just the beginning, however, as the effectiveness of a vaccine is only as good as its delivery system.
Experts are recommending that adolescents and some adults be vaccinated against whooping cough to help prevent infection and potential transmission to infants, according to the December 15 issue of Clinical Infectious Diseases, now available online.
To stick to cells in the respiratory tract and start an infection, the bacterium Haemophilus influenza has to secrete a glue-like protein. Researchers at Washington University School of Medicine in St. Louis report this week that a study of the valve that lets out the glue has produced some surprising information.
The Ministry of Health's Dr Alison Roberts says "Numbers have been on the rise since June this year, but they really spiked up in August. We have been expecting an epidemic around now.
Western Australia is experiencing the highest level of whooping cough (pertussis) notifications since 1997, when more than 1200 cases were notified.
Pertussis is a contagious illness caused by bacteria. It occurs in infants and young children more often than older children and adults. Adults with milder, undiagnosed symptoms can transmit the disease to infants and children.
Little is known about the causes of lymphoma. A case-control study conducted by Professor Nikolaus Becker and Dr. Alexandra Nieters, Division of Clinical Epidemiology at the Deutsches Krebsforschungszentrum (German Cancer Research Center, DKFZ), is looking closely at possible risk factors.
From the end of September these vaccines will be given in the routine vaccination schedule in a combined vaccine along with Diphtheria, Tetanus, and Hib.
The British government has announced plans for a new combined vaccination for babies and children. A single jab will protect children against diphtheria, tetanus, pertussis (whooping cough), Haemophilus influenzae type B (Hib), and polio.
The U. S. Department of Health and Human Services has announced that the nation's childhood immunization rates are at record high levels, including significant increases in rates of immunization for chickenpox and pneumococcal pneumonia, the two most recent additions to the childhood immunization schedule.
