Contract notice: supply of vaccine doses against diphtheria and tetanus, reduced antigenic
In conjunction, HeptaVac was designed to elicit cellular immunity and contains antigenic
peptides from the H1N1 influenza virus proteins, two of which represent conserved sequences between the seasonal and pandemic strains, revealed the company.
The virus has been classified into nine serological species or groups (A-I) based on the antigenic
properties of inner capsid protein (VP6) (Mihalov-Kovacs et al.
The viruses in cluster IV formed at least 2 antigenic
subclusters, H3N2-[alpha] and H3N2-[beta] (5).
Earlier research had found that five regions of H1N1's HA serve as antigenic
sites, the protein fragments that activate the body's immune system.
This shape-shifting, called antigenic
drift, is why influenza vaccines a[euro]" which are designed to elicit antibodies matched to each year's circulating virus strains a[euro]" must be reformulated annually.
created a latex raw material called Vytex Natural Rubber Latex (NRL) that not only retains the eco-friendly nature of NRL, but significantly reduces the antigenic
proteins found in natural rubber latex--the reason why some have moved away from latex.
Annual human influenza epidemics occur because the influenza viruses change their antigenic
drift') to produce new strains that can cause infection in persons who have been previously infected or vaccinated with different strains.
University of Kentucky (Lexington, KY) has patented novel isolated nucleic acids encoding antigenic
proteins derived from Sarcocystis neurona, or unique fragments thereof.
Although laboratory data on the antigenic
characteristics of circulating influenza viruses compared with vaccine strains are available during influenza seasons, estimates of VE usually have not been made until months after the conclusion of the season.
Vytex NRL is natural rubber latex that has undergone a proprietary process removing the antigenic
proteins that trigger allergic reactions.
New adjuvants should help to reduce the amount of antigenic
viral material in each vaccine dose that is necessary to induce protective immunity, Dr.
