many parents today haven't seen the effects of a widespread polio epidemic or a measles outbreak, diseases that still prevail in countries where vaccines are unaffordable. But what those parents may have seen, however, are reports that
The Inspiration for Vaccines Who knew that cows would save the lives of countless humans? In 1796, a physician named Edward Jenner decided to prove a theory that had been circulating for some time. Smallpox once killed millions of people worldwide. Cowpox was a less serious disease related to...
Inactivated vaccines:When inactivated vaccines are made, the bacteria is completely killed using a chemical, usually formaldehyde. Dead pieces of disease-causing microorganisms (usually bacteria) are put into the vaccine. Because the antigens are dead, the strength of these vaccines tends to wear off...
Deadly outbreaks have plagued societies for centuries. But they can lead to medical breakthroughs—if we learn the right lessons from them.
Not always, but raccoons may carryinfectious diseasessuch as rabies, distemper, or Baylisascaris procyonis, which is a roundworm infection. They also may carry fleas and ticks. If you have pets that go outdoors, keep them up-to-date on their vaccines in case they come in contact with a si...
At present, the complete inactivation of rabies virus in rabies vaccines ad us. vet. is proven by an animal experiment which causes severe suffering, the intracerebral injection of mice. This animal experiment yet is not validated. We have quantified the sensitivity of the mouse test and examined...
The duration of protection relies largely on B-cell memory responses, although the persistence of antibody production is often crucial for combating rapidly invasive infections. T-cell responses to existing vaccines are undoubtedly of importance but they have not been extensively analyzed. Antigenic ...
But how much do animals think about their blood types? Presumably never, given what we know about animal cognition. But we humans do think about our animals, because sometimes animals receive blood transfusions too, and we want to make sure the blood we're giving a ferret or dog or parake...
This time, vaccine-happy pediatricians couldn’t say that vitamins and minerals are unproven when the vaccines themselves were experimental and as a class (reprogrammable RNA/DNA vaccines) have never been used in humans before. But as much as I am an advocate of immune-boosting dietary supplement...
(pDCs), and which are responsible for the efficient activation of natural killer (NK) cells, invariant NKT cells (iNKT cells) and T cells22, the effects of IFN antagonism are impli- cated not only in the high viral burdens late in the course of disease, but also in much of the early...
