They will be enrolled into the trial three people at a time with frequent monitoring of the vaccine safety.
The story, briefly, is that, in the late 1990s, a pretty good (not great) vaccine demonstrated a real reduction in Lyme cases.
We must be careful not to administer a vaccine against faith to them.
Of course not—the delivery of vaccine from manufacturer to arm is only part of the problem for any vaccination program.
The protection offered by the current vaccine also wanes more rapidly than researchers once thought.
It is not impossible, since Jenner found the vaccine virus, Pasteur the hydrophobic lymph and now Koch the tubercle lymph.
When unsuccessful, the vaccine matter or the technique is faulty.
As a rule, the propriety of using a vaccine can be determined from the general condition of the patient.
Meanwhile the bacteriologists are steadily at work on a vaccine or antitoxin.
Favourable results have also followed the use of pyocyanase, a vaccine prepared from the bacillus pyocyaneus.
vaccine vac·cine (vāk-sēn' vāk'sēn')
A preparation of a weakened or killed pathogen, such as a bacterium or virus, or of a portion of the pathogen's structure that upon administration stimulates antibody production against the pathogen but is incapable of causing severe infection.
A vaccine prepared from the cowpox virus and inoculated against smallpox.
A preparation of a weakened or killed pathogen, such as a bacterium or virus, or of a portion of the pathogen's structure, that stimulates immune cells to recognize and attack it, especially through antibody production. Most vaccines are given orally or by intramuscular or subcutaneous injection. See Note at Jenner.
Our Living Language : In the 1950s, polio epidemics left thousands of children with permanent physical disabilities. Today, infants are given a vaccine to prevent infection with the polio virus. That vaccine, like most others, works by stimulating the body's immune system to produce antibodies that destroy pathogens. Scientists usually prepare vaccines by taking a sample of the pathogen and destroying or weakening it with heat or chemicals. The inactivated or attenuated pathogen loses its ability to cause serious illness but is still able to stimulate antibody production, thereby conferring immunity. The Salk polio vaccine contains "killed" virus, while the Sabin polio vaccine contains weakened "live" poliovirus. (Many scientists no longer consider viruses to be living organisms) Scientists are also able to change the structure of viruses and bacteria at the molecular level, altering DNA so that the potential of the vaccine to cause disease is decreased. New vaccines containing harmless bits of DNA have also been developed.
