How do vaccines protect you against viruses?
7
Explain how the salk and sabin vaccines provide protection against polio?
Vaccines provide protection by reproducing antibodies which fights the poliovirus, or whatever the virus is the vaccine is intended to protect against. Some vaccines may also protect against certain bacterial infections, such as pneumonia.
Do vaccines work against viruses and bacteria?
No. Vaccines are not used for treatment. They are used as prevention.
What combination vaccines contains antigens to protect against hepatitis A and hepatitis B?
Twinrix
How many types of HPV does the vaccine protect against?
Different HPV vaccines protect against different numbers of subtypes. There have been bivalent and tetravalent vaccines on the market to date. A new 9-valent vaccine was just approved in late 2014.
If canine vaccines are not cold can they still be given and will they still protect against illnesses?
If the vaccines are supposed to be kept refrigerated until use, they are worthless if they are no longer cold.
What are vacines made from?
Vaccines are typically made from a dead or inert version of the virus it is intended to protect against. Usually vaccines are incubated in an egg based fluid.
What are the most common vaccines used to protect against infections for splenectomies?
The most common vaccines used are Pneumovax or Pnu-Imune 23 (against pneumococcal infections) and Menomune-A/C/Y/W-135 (against meningococcal infections).
Why are some vaccines not suitable for all diseases?
Simply put there are to many diseases. Some of the existing vaccines, pneumovax for example,only protect against a certain bacteria, and the flu vaccine is redeveloped each year to protect against the strain that is predicted to be the most prevalent. Others, like shingles vaccine protect against the disease, do NOT guarantee immunity but help to lessen the severity and pain associated with the disease.
What are people opinon on vaccination that have side effects?
Side effects are generally mild, and occur sparingly. The diseases the vaccines PROTECT against, however, can leave people crippled, seriously ill, or can kill (but in a horrible, painful way). Believe me when I say, the vaccines are far better than the diseases they protect against, even if there are side effects.
What stimulate interferons that production and how do they protect uninfected cells?
Interferons are typically stimulated by viral or bacterial infections. They protect uninfected cells by binding to receptors on the cell surface, triggering a signaling cascade that results in the production of antiviral proteins, which help defend the cell against infection. This interferon-induced antiviral response acts as an early warning system that limits viral spread to neighboring cells.
How does immunisation protect us against cancer?
A universal vaccine against cancer does not exist. But you can protect yourself from those types of oncology that are caused by viruses. Among them are cervical cancer, liver cancer, Burkitt's lymphoma. It is proved that most of these diseases are caused by the virus. So, you need to make a vaccine against human papillomavirus (HPV) to protect yourself from cervical cancer. Vaccines against all types of tumors are being developed, but not applied. These vaccines are not still effective and safe enough.
