Less time was used for the rabbits to produce the PAbs with a higher titer and production, so the rabbit was chosen to produce PAbs in the subsequent experiments.
Conclusion:The purified fusion protein has good fineness and hemolysis activity, the antibody titers initiated by the protein vaccine go with regulation and the immunoprotection is satisfied.
I tend to give boosters if I see low titer, and I tend to be checking titers more than before because of the outbreaks and because of what I said in Europe and people traveling to Europe.
The reason for doing titers in an immunocompromised person who I cannot give the shot to is to let them know that their risk may be higher than they realize.
