Vaccination schedule

A vaccination schedule is a series of vaccinations, including the timing of all doses, which may be either recommended or compulsory, depending on the country of residence. A vaccine is an antigenic preparation used to produce active immunity to a disease, in order to prevent or reduce the effects of infection by any natural or "wild" pathogen. Vaccines go through multiple phases of trials to ensure safety and effectiveness. World Health Organization-guided childhood vaccine schedules protect against 30 infectious diseases, and following them is crucial to prevent risks to children and the community, having saved over 154 million lives in the past 50 years. Many vaccines require multiple doses for maximum effectiveness, either to produce sufficient initial immune response or to boost response that fades over time. For example, tetanus vaccine boosters are often recommended every 10 years. Vaccine schedules are developed by governmental agencies or physicians groups to achieve maximum effectiveness using required and recommended vaccines for a locality while minimizing the number of health care system interactions. Over the past two decades, the recommended vaccination schedule has grown rapidly and become more complicated as many new vaccines have been developed. Some vaccines are recommended only in certain areas (countries, sub national areas, or at-risk populations) where a disease is common. For instance, yellow fever vaccination is on the routine vaccine schedule of French Guiana, is recommended in certain regions of Brazil but in the United States is only given to travelers heading to countries with a history of the disease. In developing countries, vaccine recommendations also take into account the level of health care access, the cost of vaccines and issues with vaccine availability and storage. Sample vaccination schedules discussed by the World Health Organization show a developed country using a schedule which extends over the first five years of a child's life and uses vaccines which cost over $700 including administration costs while a developing country uses a schedule providing vaccines in the first 9 months of life and costing only $25. This difference is due to the lower cost of health care, the lower cost of many vaccines provided to developing nations, and that more expensive vaccines, often for less common diseases, are not utilized.

• What parents need to know about the overhauled childhood vaccine schedule

  The US Department of Health and Human Services is changing the childhood vaccine schedule — a set of recommendations from the federal government about what immunizations children should get and when — to scale back the number of vaccines broadly recommended for children. These are recommendations, not mandates, but the schedule is typically used to guide which vaccines states require for day care or public school, as well as which vaccines are covered by insurance. The new schedule recommends that healthy children get 11 vaccines — fewer than were previously recommended broadly. [...] ## Can children be vaccinated according to previous CDC schedules? The vaccine schedule is a set of recommendations from federal officials. It doesn’t make kids get certain shots, nor does it forbid them from getting others. So parents should technically be able to get their children vaccinated according to the previous schedule. Experts say it’s especially important now to have a good conversation with the child’s pediatrician about what shots they suggest. [...] ## Why is the vaccine schedule changing? The new schedule wasn’t driven by any new evidence on the safety and effectiveness of vaccines. In December, President Donald Trump ordered HHS to review the schedule along with those of other developed nations. HHS says that reducing the number of vaccines for children gives parents more “flexibility and choice, with less coercion.” HHS Secretary Robert F. Kennedy Jr., who has been an outspoken vaccine skeptic for years, also said the change to the schedule “protects children, respects families, and rebuilds trust in public health.”

• Health officials slash the number of vaccines recommended for all kids

  Listen · 4:12 Transcript Download `<iframe src=" width="100%" height="290" frameborder="0" scrolling="no" title="NPR embedded audio player">` Transcript The Centers for Disease Control and Prevention has developed a new vaccine schedule that would reduce the number of routine vaccinations for all kids. Joe Raedle/Getty Images hide caption toggle caption Joe Raedle/Getty Images In an unprecedented change, the Centers for Disease Control and Prevention is reducing the number of vaccines routinely recommended for all children from 17 to 11. [...] The changes to the schedule came after a "comprehensive scientific assessment" comparing U.S. policy with that of 20 other countries, said a senior administration health official who briefed reporters on the condition of anonymity. The assessment was authored by Martin Kulldorff, chief science officer at a unit of HHS who served briefly as chair of the CDC's vaccine advisory committee last year, and Tracy Beth Høeg, acting director of the FDA's Center for Drug Evaluation and Research. The changes were made without formal public comment or input from vaccine makers, officials confirmed, circumventing the typical process in which many stakeholders, including the CDC's Advisory Committee on Immunization Practices, weigh in on the benefits and risks of any changes to the vaccine schedule. [...] On the new schedule, vaccines that had previously been recommended for all children — such as those for rotavirus, hepatitis A and B, meningitis and seasonal flu — are now more restricted. They are recommended only for those at high risk or after consultation with a health care provider, a category called "shared decision-making." Health Secretary Robert F. Kennedy Jr. has long questioned the safety and effectiveness of many childhood vaccines. With this overhaul, the administration is taking a dramatic step to pare down the schedule of immunizations routinely recommended for all children. ### Public Health ### CDC advisers vote to overturn decades-long policy on hepatitis B vaccine for infants

• States, health organizations reject new CDC vaccine guidance

  # States, health organizations reject new CDC vaccine guidance Liz Szabo, MA Public Health Childhood Vaccines > Mohamad Faizal Bin Ramli / iStock Copied to clipboard A growing number of states are pushing back against sweeping changes to the US childhood vaccine schedule. The Centers for Disease Control and Prevention (CDC) announced an overhaul of the immunization schedule January 5, paring the number of universally recommended immunizations from 17 to 11. Since then, at least 17 states have announced that they won’t follow new CDC vaccine schedule: California, Colorado, Connecticut, Hawaii, Illinois, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New York, North Carolina, Oregon, Pennsylvania, Vermont, Washington, and Wisconsin.
