HAI and NAI titer correlates of inactivated and live attenuated influenza vaccine efficacy.

Gilbert PB, Fong Y, Juraska M, Carpp LN, Monto AS, Martin ET, Petrie JG.
BMC infectious diseases. 2019 May;19(1)453.
High hemagglutination inhibition (HAI) and neuraminidase inhibition (NAI) titers are generally associated with reduced influenza risk. While repeated influenza vaccination reduces seroresponse, vaccine effectiveness is not always reduced. During the 2007-2008 influenza season, a randomized, placebo-

Muscovy ducks infected with velogenic Newcastle disease virus (genotype VIId) act as carriers to infect in-contact chickens.

Elbestawy AR, Ellakany HF, El-Hamid HSA, Zedan RE, Gado AR, Sedeik ME, Abd El-Hack ME, Saadeldin IM, Alowaimer AN, Ba-Awadh HA, Swelum AA.
Poultry science. 2019 May;().
This work was designed to study the dynamics of transmission of Newcastle disease virus (NDV), genotype VIId, from Muscovy ducks (Cariana moscata) infected either by intramuscular (IM) or intranasal (IN) inoculation, to in-contact broiler chickens (Gallus gallus). IM-infected Muscovy ducks (G1d) exh

Hemagglutination Inhibition Antibody Response Following Influenza A(H1N1)pdm09 Virus Natural Infection: A Cross-Sectional Study from Thirthahalli, Karnataka, India.

Alladi CSH, Jagadesh A, Prabhu SG, Arunkumar G.
Viral immunology. 2019 May;().
Influenza viruses are major respiratory pathogens that cause seasonal epidemics and occasional pandemics. Immune response to influenza viruses is majorly targeted against the hemagglutinin antigen. A laboratory-based retrospective cross-sectional study was conducted on 50 acute and 50 follow-up samp

保健医療科学 66(1), 47-55, 2017
目的：近年，本邦における妊娠可能年齢女性の風疹抗体保有率の低下が問題となっている．風疹予防対策の一つとして，厚生労働省は風疹低抗体価の妊婦に対し，次回妊娠時の先天性風疹症候群発症リスク低下のため，産後早期の風疹ワクチン接種を強く推奨すると2004年に発表した．一方，産婦人科診療ガイドラインでは産褥風疹ワクチン推奨レベルはC（実施が考慮される）であるため，医療施設の対応に差があり，産褥風疹ワクチン接 …
