Advances in Neoantigen-Based Cancer Vaccines.

Neoantigen-based immunotherapies harness somatic mutations as tumor-specific targets and represent a major advance in personalized cancer treatment. Since neoantigens are presented exclusively on cancer cells, they enable highly selective T-cell recognition with minimal off-tumor toxicity. Neoantigen vaccines are rapidly emerging as a versatile class of personalized cancer immunotherapies designed to prime tumor-specific T cells by targeting somatic mutations unique to each patient's tumor. Multiple types of neoantigen vaccines, using peptide, mRNA, and DNA, have shown feasibility, safety, and…

Natural Attenuated Vaccines for Pasteurella multocida.

Pasteurella multocida is capable of infecting various animal species, causing hemorrhagic septicemia or infectious pneumonia, and it is widely prevalent and pathogenic worldwide. However, the prevention and control technologies for animal pasteurellosis remain relatively under-developed, with a heavy reliance on the traditional inactivated vaccines and live attenuated vaccines developed in the mid-20th century. A previous systematic review summarized research progress in the field of inactivated vaccines for animal pasteurellosis and revealed that inactivated vaccines exhibit high levels of ho…

New Vaccines for Chronic Respiratory Patients.

Chronic respiratory diseases (CRD) are responsible for more than four million deaths worldwide and have become especially prevalent in developed countries. Although the current therapies help manage daily symptoms and improve patients' quality of life, there is a major need to prevent exacerbations triggered mainly by respiratory infections. Therefore, CRD patients are a prime target for vaccination against infectious agents. In the present manuscript we review the state of the art of available vaccines specifically indicated in patients with CRDs. In addition to pneumococcus, influenza, pertu…

Viral vector-based therapeutic HPV vaccines.

Replication-defective viral vector vaccines have several advantages over conventional subunit vaccines, including potent antibody responses, cellular responses critical for eliminating pathogen-infected cells, and the induction of highly immunogenic and durable immune responses without adjuvants. The Human papillomavirus (HPV), a microorganism with over 200 genotypes, plays a crucial role in inducing human tumors, with the majority of HPV-related malignancies expressing HPV proteins. Tumors associated with HPV infection, most of which result from HPV16 infection, include those affecting the ce…

Poxvirus Vaccines: Past, Present, and Future.

Smallpox was a significant cause of mortality for over three thousand years, amounting to 10% of deaths yearly. Edward Jenner discovered smallpox vaccination in 1796, which rapidly became a smallpox infection preventive practice throughout the world and eradicated smallpox infection by 1980. After smallpox eradication, monkeypox vaccines have been used primarily in research and in outbreaks in Africa, where the disease is endemic. In the present, the vaccines are being used for people who work with animals or in high-risk areas, as well as for healthcare workers treating patients with monkeypo…

Chikungunya vaccines: An update in 2023.

A recent chikungunya outbreak affected 1.5 million cases in more than 60 countries. The virus causes low mortality but moderate to severe morbidities such as high fever, myalgia, and polyarthritis. The chikungunya virus is transmitted by Aedes spp. mosquitoes, of which the population has increased due to urbanization and global warming. Currently, no commercial vaccine is available, but several candidates are being tested in clinical trials. This review aimed to summarize the recent updates of candidates on each platform, ranging from traditional inactivation, live attenuation with reverse gen

Evaluating immune responses to pneumococcal vaccines.

Streptococcus pneumoniae (pneumococcus) is a significant cause of bacterial infections ranging from mild infections affecting the respiratory tract such as otitis media and sinusitis to severe diseases including bacteremia, pneumonia, and invasive pneumococcal disease (IPD) (eg, meningitis, septic arthritis, and endocarditis). Pneumococcal vaccines were first developed in the 1970s as capsular pneumococcal polysaccharide vaccines, which were T-cell independent and hence lacked immunologic memory. Subsequently in the year 2000, pneumococcal conjugate vaccines (PCV) conjugated to a protein to in…

Patient Perspective: Vaccines for Older People.

Pharmacists, as one of the most accessible health care professionals in the community, can educate, promote, and administer vaccinations. Im … administration and rates. Other concerns for older people are the cost, safety, and side effects of vaccines. In addition, updated vaccine guidelines were released by the Centers for Disease Control and Prevention (CDC) in early 2023 that affect recommendations for influenza, COVID-19, and pneumonia vaccines. Older people are at higher risk for severe illn …

Equitable global allocation of monkeypox vaccines.

With the world grappling with continued spread of monkeypox internationally, vaccines play a crucial role in mitigating the harms from infection and preventing spread. However, countries with the greatest need - particularly historically endemic countries with the highest monkeypox case-fatality rates - are not able to acquire scarce vaccines. This is unjust, and requires rectification through equitable allocation of vaccines globally. We propose applying the Fair Priority Model for such allocation, which emphasizes three key principles: 1) preventing harm; 2) prioritizing the disadvantaged; a…

Рисковый научный взгляд на вакцины.

Вакцины можно рассматривать как один из величайших достижений современной медицины. Хорошими примерами являются вакцины от оспы, полиомиелита и кори. К сожалению, вакцины могут иметь побочные эффекты, однако медицинские органы и эксперты считают риски незначительными по сравнению с их выгодами. Тем не менее есть много людей, которые скептически относятся к вакцинации, что было очень четко продемонстрировано в связи с болезнью COVID-19. Риск является ключевым понятием при оценке вакцины как с точки зрения ее способности защититься от этого заболевания, так и от его побочных эффектов. Однако изм
