by The Development of Vaccinations
One of the most significant medical advances in history has been the development of vaccines. Pioneering scientists and doctors in the 18th and 19th centuries discovered that exposing people to small doses of certain diseases could help them develop immunity without becoming seriously ill. Some of the earliest successful vaccines were for diseases like smallpox and rabies. By the late 19th century, additional vaccines had been developed for diseases such as cholera, plague, and typhoid fever. During the 20th century, microbiologists discovered the specific bacteria and viruses that cause many infectious illnesses. This paved the way for new vaccines to be created through modern methods.
The Impact of Recommended Childhood Vaccines
Today in the U.S. Vaccine, the Centers for Disease Control and Prevention (CDC) recommends that all children receive vaccines to protect them from 14 serious diseases by age two. These diseases include measles, mumps, rubella, polio, diphtheria, tetanus, pertussis, hepatitis B, rotavirus gastroenteritis, Haemophilus influenzae type b, pneumococcal disease, and annual influenza vaccines. Following the recommended vaccination schedule has had tremendous positive impacts on public health. For example, cases of measles fell from hundreds of thousands per year to virtually zero by the 2000s after an effective measles vaccine was introduced in the 1960s. Likewise, cases of Hib meningitis declined by 99% after the Hib vaccine was added to the schedule in the 1990s. Continuing high vaccination rates are needed to maintain immunity levels in the population and prevent dangerous outbreaks.
Challenges with Anti-Vaccination Sentiments
Despite the clear benefits, vaccination rates for some diseases have fallen below herd immunity levels in certain communities due to anti-vaccination beliefs. Certain groups oppose vaccines due to concerns about side effects, autism links, and mistrust of pharmaceutical companies or the government. However, repeated scientific studies have found no evidence that vaccines cause autism or other health issues. When vaccination rates fall, outbreaks can and do occur, such as with the recent 2019 measles outbreak in the Pacific Northwest. Public health organizations devote resources to countering misinformation and promoting vaccination through education programs. Regulations like school vaccination requirements also aim to increase community protection. However, vaccination opponents continue lobbying against such policies. Finding an effective way to address anti-vaccination sentiments remains an ongoing public health challenge.
The Continued Development of New Vaccines
Scientists have worked to develop new U.S. Vaccine to protect against additional diseases. In the 1990s, vaccines were created for rotavirus, which is a common cause of diarrhea in infants and young children globally. More recently, FDA-approved vaccines have been developed for human papillomavirus (HPV), which can lead to cervical and other cancers. Researchers are also making strides towards vaccines for diseases that have long proved difficult like HIV/AIDS, tuberculosis, malaria and Ebola virus. New technologies based on mRNA, DNA vectors and protein subunits are allowing vaccine designers to target diseases in innovative ways without using live pathogens. Going forward, improved global coordination and funding for vaccine research could help accelerate the development of vaccines that save countless lives worldwide each year for years to come.
Ensuring Access and Affordability
While vaccines deliver excellent value by preventing costly illnesses, access and affordability challenges remain for some populations. The Vaccines for Children (VFC) program helps provide recommended vaccinations free of charge to children whose parents may not be able to afford them. However, vaccine costs still present barriers for some adults or those not eligible for VFC. Other countries face even greater economic obstacles to widespread vaccination programs. Multinational partnerships aim to make new generation vaccines affordable in developing countries. Still, even in the United States, rising healthcare and prescription drug costs threaten insurance coverage for vaccinations. Ensuring all people can obtain recommended immunizations regardless of ability to pay continues being a priority public health goal. Coordinated efforts are vital so the benefits of vaccines can protect communities everywhere.
U.S. Vaccine stand out as one of humanity’s greatest public health achievements. Continued progress on developing new vaccines, addressing challenges to increasing access and herd immunity levels worldwide will help further control contagious illnesses. With continued scientific progress and strong policies in place, vaccines’ ability to protect communities from harm can endure far into the future.
