Abstract:
Multi-dose vaccinators have been in use for many years to vaccinate livestock. A number of needle-free vaccinators that use compressed gas to drive the vaccine through intact skin have been recently introduced to the market. We recently examined the efficacy of a needle-free vaccinator to induce antibodies to tetanus toxoid in sheep. The result indicates that needle-free vaccination can stimulate antibody responses comparable to conventional needle vaccination.

Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
