  • Rubella vaccine

    Rubella vaccine is a vaccine used to prevent rubella. Effectiveness begins about two weeks after a single dose and around 95% of people become immune. Countries with high rates of immunization no longer see cases of rubella or congenital rubella syndrome. When there is a low level of childhood immunization in a population it is possible for rates of congenital rubella to increase as more women make it to child bearing age without either vaccination or exposure to the disease. Therefore, it is important for more than 80% of people to be vaccinated.

  • Historical annual reformulations of the influenza vaccine

    Since 1999, the World Health Organization has issued annual recommendations for influenza vaccine formulations. One reformulation of the influenza vaccine is for the Northern Hemisphere, and the other is for the Southern Hemisphere. Both recommendations are trivalent, i.e. featuring three strains.

  • Ebola vaccine

    Ebola vaccine

    Ebola vaccine candidates against Ebola have been developed in the decade prior to 2014, but none have yet been approved for clinical use in humans. One, rVSV-ZEBOV, has been used extensively in 2018-19 under a compassionate use protocol, and in September 2019, the FDA accepted a Biologics License Application and granted priority review for the vaccine. Several promising vaccine candidates have been shown to protect nonhuman primates (usually macaques ) against lethal infection.

  • Hookworm vaccine

    Hookworm vaccine is a vaccine against hookworm. No effective vaccine for the disease in humans has yet been developed. Hookworms, parasitic nematodes transmitted in soil, infect approximately 700 million humans, particularly in tropical regions of the world where endemic hookworms include Ancylostoma duodenale and Necator americanus . Hookworms feed on blood and those infected with hookworms may suffer from chronic anaemia and malnutrition. Helminth infection can be effectively treated with benzimidazole drugs (such as mebendazole or albendazole ), and efforts led by the World Health Organization have focused on one to three yearly de-worming doses in schools because hookworm infections with the heaviest intensities are most common in school-age children. However, these drugs only eliminate existing adult parasites and re-infection can occur soon after treatment, school-based de-worming efforts do not treat adults or pre-school children, and concerns exist about drug resistance developing in hookworms against the commonly used treatments, thus a vaccine against hookworm disease is sought to provide more permanent resistance to infection.
