What is polyvalent?
In connection with chemistry, it describes polyvalent atoms that can create more than two links. In medicine, this term also applies to multiple capacities. It almost always applies to medical measures that can deal with more than one condition, and these treatments could be vaccines, antivenings that help people recover from more than one type of poisonous bites, or medicines that work against multiple microorganisms.
There are numerous examples of polyvalent vaccines and are likely to be developed more. The advantage of multiple vaccinations in one shot is clear to most people; Greater protection of diseases with less shots is attractive and can be cheaper. Some of the polyvalent vaccines include measles, mumps and rubella (MMR) and tetanus, diphtheria and pertussis (TDAP). The vaccine can alternately protect against different types of the same disease. Pneumovax® provides protection against 23 bacteria that can create pneumonia, and Gardasil & Rnípř; should killWound four types of human papillomavirus (HPV), which are most associated with the development of cervical cancer.
Not all vaccines are polyvalent, which may mean that they have not yet been combined in more forms, or mixing them with other vaccines could reduce their effectiveness. Another aspect is how many times the vaccine must be delivered for full effect. There is no point in combining vaccinations that have different delivery timelines. A combination of something that must be given every six months with something that must be given every ten years of medicine.
Unlike vaccines, the antiven is only given if one receives a poisonous bite. In areas where there are many poisonous creatures, it is easy to understand why it is highly beneficial to have a swallowed antiven, which is handling multiple types of bites. It can be cheaper than creature-specific antiven and could reduce the problems associated with the wearing nobo storage of drugs.
Examples of polyvalent antiven antivenings include one made in India, which will respond against magnificent Cobry, Common Krait, Russell's Viper and Viper Scaled Viper. There is also another type to treat all Iranian scorpions and there is one that can reduce the disease after bite from brown and black widow spiders. Simple antivenings in Australia can work against almost all Australian poisonous snakes.
As with vaccination, a combination of different antivenings may be practical or impractical and it does not always work. Polyval antivenings are most practical in areas with a larger number of poisonous animals, fish or insects that are likely to come into contact with humans. In many cases, this makes no sense to combine two or more antivenings unless more than one type is needed often.
other treatments can effectively kill a mood than one type of bacteria or parasite. Most antibacterial drugs show a swallownci. There are also many types of vernifuges or antiparasitic drugs that will treat more than one type of infection; For example, medicines could kill round worms, hooks and tapeworms and be prescribed for some of these contaminants.
