What are the 4 types of vaccines?

Four types of vaccines are currently available:

  • Live virus vaccines use the weakened (attenuated) form of the virus.
  • Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria.
  • Toxoid vaccines contain a toxin or chemical made by the bacteria or virus.
  • Besides, which vaccines are live and which are inactivated?

  • Inactivated (killed antigen) Subunit (purified antigen)
  • Toxoid (inactivated toxins) – Tuberculosis (BCG)
  • – Oral polio vaccine (OPV) – Measles.
  • – Rotavirus. – Yellow fever.
  • – Whole-cell pertussis (wP) – Inactivated polio virus (IPV)
  • – Acellular pertussis (aP),
  • – Pneumococcal (PCV-7, PCV-10, PCV-13)
  • – Tetanus toxoid (TT),
  • How do vaccines work on viruses?

    Vaccines are like a training course for the immune system. They prepare the body to fight disease without exposing it to disease symptoms. When foreign invaders such as bacteria or viruses enter the body, immune cells called lymphocytes respond by producing antibodies, which are protein molecules.

    What is a receptor in a virus?

    Cell surface protein used by a virus as an attachment and entry receptor. In some cases, binding to a cellular receptor is not sufficient for infection: an additional cell surface molecule, or co-receptor, is required for entry. Some viruses are able to use different receptors depending on the target cell type.

    What are the 5 types of vaccines?

    Different Types of Vaccines

  • Vaccinia (smallpox)
  • Measles, mumps, rubella (MMR combined vaccine)
  • Varicella (chickenpox)
  • Influenza (nasal spray)
  • Rotavirus.
  • Zoster (shingles)
  • Yellow fever.
  • What is a type of vaccine?

    Live vaccines are used to protect against:

  • Measles, mumps, rubella (MMR combined vaccine)
  • Rotavirus.
  • Smallpox.
  • Chickenpox.
  • Yellow fever.
  • What type of vaccine is Gardasil?

    Gardasil, also known as Gardisil or Silgard or recombinant human papillomavirus vaccine [types 6, 11, 16, 18], is a vaccine for use in the prevention of certain strains of human papillomavirus (HPV), specifically HPV types 6, 11, 16 and 18.

    Which vaccines are live attenuated?

    Viral: measles vaccine, mumps vaccine, rubella vaccine, live attenuated influenza vaccine (the seasonal flu nasal spray and the 2009 H1N1 flu nasal spray), chicken pox vaccine, smallpox vaccine, oral polio vaccine (Sabin), rotavirus vaccine, and yellow fever vaccine.

    What type of vaccine is the flu shot?

    Traditional flu vaccines (called “trivalent” vaccines) are made to protect against three flu viruses; an influenza A (H1N1) virus, an influenza A (H3N2) virus, and an influenza B virus. There are also flu vaccines made to protect against four flu viruses (called “quadrivalent” vaccines).

    Which vaccines are commonly given?

    Write the following vaccines on the board:

  • Polio.
  • MMR (measles, mumps, rubella)
  • DTP (diphtheria, tetanus, pertussis)
  • Hepatitis B.
  • Varicella (chicken pox)
  • What is the difference between a vaccine and an antibiotic?

    There are many different types of antibiotics and they act on the bacteria in different ways. Some antibiotics act by killing the bacteria while others prevent the bacteria from multiplying, leaving your own immune system to ‘mop them up’. Vaccines are used to prevent infection, particularly viral infections.

    Is the rotavirus vaccine a live vaccine?

    Rotavirus vaccine live is used to prevent infants and children from getting a rotavirus stomach infection. It works by causing your body to produce its own protection (antibodies) against the virus. Rotavirus is a serious infection that causes diarrhea and vomiting.

    What type of vaccine is HPV vaccine?

    Human papilloma virus (HPV) vaccines are vaccines that prevent infection by certain types of human papillomavirus. Available vaccines protect against either two, four, or nine types of HPV. All vaccines protect against at least HPV type 16 and 18 that cause the greatest risk of cervical cancer.

    What is meant by recombinant vaccine?

    A recombinant vaccine is a vaccine produced through recombinant DNA technology. This involves inserting the DNA encoding an antigen (such as a bacterial surface protein) that stimulates an immune response into bacterial or mammalian cells, expressing the antigen in these cells and then purifying it from them.

    Is the pneumococcal vaccine a live vaccine?

    The pneumococcal vaccine is thought to be around 50-70% effective at preventing pneumococcal disease. Both the PPV and the PCV are inactivated or “killed” vaccines and don’t contain any live organisms. They can’t cause the disease against which they protect.

    What is a vaccine made up of?

    The hepatitis B and the human papillomavirus (HPV) vaccines are made this way. The vaccine is composed of a protein that resides on the surface of the virus. This strategy can be used when an immune response to one part of the virus (or bacteria) is responsible for protection against disease.

    What is an active vaccine?

    Active immunization is the induction of immunity after exposure to an antigen. Antibodies are created by the recipient and may be stored permanently. Artificial active immunization is where the microbe is injected into the person before they are able to take it in naturally.

    What type of vaccine is the BCG?

    BCG, or bacille Calmette-Guerin, is a vaccine for tuberculosis (TB) disease. Many foreign-born persons have been BCG-vaccinated. BCG is used in many countries with a high prevalence of TB to prevent childhood tuberculous meningitis and miliary disease.

    What is a bacterial vaccine?

    Summary. Most vaccines against bacterial infections are effective at preventing disease. Reactions can occur after vaccinations. Vaccines are available against tuberculosis, diphtheria, tetanus, pertussis, Haemophilus influenzae type B, cholera, typhoid, and Streptococcus pneumoniae.

    Do they still give polio vaccines?

    Inactivated polio vaccine (IPV) is the only polio vaccine that has been given in the United States since 2000. It is given by shot in the arm or leg, depending on the person’s age. Oral polio vaccine (OPV) is used in other countries. CDC recommends that children get four doses of polio vaccine.

    Is tetanus live?

    The tetanus immunization is not a live virus vaccine. It is a toxoid meaning that the immune reaction is against the toxin produced the bacteria causing tetanus. This means that the immune reaction is not against the bacteria, but this bad protein that can make people sick.

    What is in the vaccine?

    These are the parts of the vaccine made from viruses or bacteria (also called ‘antigens’). They challenge the immune system so that it makes antibodies to fight the disease. Vaccines contain tiny quantities of active ingredients – just a few micrograms (millionths of a gram) per vaccine.

    What is the purpose of the vaccine?

    Some, such as smallpox, have now been eradicated. The purpose of vaccination is to produce immunity. Immunity means the presence in a person’s body of cells and substances known as antibodies that can produce a protective immune response.

    What type of vaccine is Hib?

    Hib vaccine. The Haemophilus influenzae type B vaccine, often called Hib vaccine, is a vaccine used to prevent Haemophilus influenzae type b (Hib) infection. In countries that include it as a routine vaccine, rates of severe Hib infections have decreased more than 90%.
