  • An example of a combination vaccine is the measles-mumps-rubella (MMR) vaccine . (immunizationinfo.org)
  • Thimerosal is currently used only in multidose vials of influenza vaccine, and exposure through vaccines is not associated with adverse neurologic outcomes. (aafp.org)
  • Influenza (flu) - The CDC recommends that everyone age 6 months of age and older get this vaccine every year before the start of flu season. (webmd.com)
  • Haemophilus influenzae type b (Hib) - The vaccine protects against a bacteria that causes dangerous brain, lung, and windpipe infections. (webmd.com)
  • An example is the development of polysaccharide-protein conjugate vaccines against Haemophilus influenzae type b. (nature.com)
  • Other vaccines that combine DTP and/or Haemophilus influenzae type b and/or hepatitis B with IPV appear feasible but require further investigation. (who.int)
  • Oral polio vaccine (OPV) is no longer available and is not recommended for routine immunization. (empr.com)
  • persons for whom oral polio vaccine (OPV) is contraindicated (i.e., persons diagnosed with or living in a household with a person with a congenital or acquired immune deficiency). (cdc.gov)
  • Both biopharmaceuticals are regarded as vaccines because they elicit an immune response, either against a pathogenic microorganism or against the host's own tumour cells. (intechopen.com)
  • Poliovirus that was grown in these cells was so "weakened" that, after it was swallowed, it induced an immune response but didn't cause disease. (chop.edu)
  • This suggests that the immune response to OPV is on a continuum, rather than an all-or-nothing phenomenon, that depends on efficient vaccine virus replication. (liverpool.ac.uk)
  • Viral interference and innate antiviral immune mechanisms might be more important determinants of the immunogenicity of live-virus oral vaccines. (ox.ac.uk)
  • The age when a vaccine works best in the immune system. (webmd.com)
  • A combination vaccine is a vaccine that consists of 2 or more separate immunogens (elements that produce an immune response from the body) physically combined into a single product. (immunizationinfo.org)
  • So researchers compare immune responses and adverse reactions of the separate components of the vaccine to those for the candidate combination vaccine. (immunizationinfo.org)
  • Pakistan began using inactivated poliovirus vaccine alongside oral vaccine in mass campaigns to accelerate eradication of This research was supported by the Research Program on wild-type poliovirus in 2014. (cdc.gov)
  • Agency for Medical Research and Development (JP17fk0108304) found that these campaigns reduced wild-type poliovirus de- and Keio Gijuku Academic Development Funds. (cdc.gov)
  • Otherwise, these persons should avoid activities or travel that might result in exposure to wild poliovirus. (cdc.gov)
  • The last reported case of poliomyelitis due to wild poliovirus type 2 was reported in 1999. (who.int)
  • In 2019, cases of wild poliovirus type 1 continued to be detected in parts of Afghanistan and Pakistan. (who.int)
  • 2 Africa was declared free of wild polio in August 2020 and only two small pockets of wild poliovirus type 1 remain, in Afghanistan and Pakistan. (bmj.com)
  • These are the wild poliovirus and the vaccine-derived poliovirus. (thehindu.com)
  • Global efforts since 1988, using oral polio vaccine to immunise children, have reduced wild poliovirus cases by 99.9% . (thehindu.com)
  • The use of the oral polio vaccine containing attenuated or weakened virus, has brought the wild poliovirus to the brink of eradication. (thehindu.com)
  • The poliovirus that has been found in sewage in the boroughs of Barnet, Brent, Camden, Enfield, Hackney, Haringey, Islington and Waltham Forest is not wild virus but derived from the vaccine. (politico.eu)
  • Currently, wild poliovirus affects Pakistan and Afghanistan. (politico.eu)
  • Three wild polioviruses cause paralytic polio-types 1, 2, and 3. (cdc.gov)
  • Polio vaccine may be given as a stand-alone vaccine, or as part of a combination vaccine (a type of vaccine that combines more than one vaccine together into one shot). (medlineplus.gov)
  • However, the children at the Watson Home received only one type of vaccine matching the strain of their original polio infection. (si.edu)
  • Adverse reactions should be reported to the Vaccine Adverse Event Reporting System (VAERS). (medlineplus.gov)
  • Because of this, parents are increasingly questioning the necessity of immunizing their children, especially because no vaccine is completely free of adverse effects or the risk of complications. (aafp.org)
  • The Vaccine Adverse Event Reporting System and National Vaccine Injury Compensation Program track adverse events and allow compensation for documented harms from vaccinations. (aafp.org)
  • Some parents express concern that physicians are not well educated on the adverse effects of vaccines or that physicians purposefully withhold information on adverse effects. (aafp.org)
  • The most common adverse effects of the human papillomavirus vaccine are transient and similar to those of other vaccines, including mild pain and bruising at the injection site, headache, lightheadedness, and syncope. (aafp.org)
