Qu and OthersĪfter two doses of mRNA vaccine, health care workers had less viral neutralizing-antibody activity against the BA.4/5 and BA.2.12.1 omicron subvariants than against the BA.1 and BA.2 subvariants, but titers increased significantly with a booster dose.

In a small trial of boost immunization with the mRNA vaccine originally received or with heterologous boosting with spike proteins from the original strain or the beta variant, the beta-adjuvanted booster resulted in the highest titers of antibody and activated T cells 2 weeks later. Correspondence Heterologous Boost with Beta Variant Spike Vaccine O.The proliferation of vaccine misinformation and its use for political purposes are placing a large number of people at risk in the Covid-19 pandemic and allowing the pandemic to continue. Review Article The Vaccine-Hesitant Moment H.J.Greater protection in the youngest group was noted. Two doses of the BNT162b2 vaccine were associated mainly with low-grade local adverse effects that lasted 2 days or less and afforded nearly 50% protection against omicron infection and symptomatic illness, which was lower than that seen against delta. Original Article Covid-19 Vaccination in Children 5 to 11 Years of Age C.J.It’s now feasible to track, for each patient seen at a health care facility, which Covid-19 vaccine they received when and what their clinical evaluation revealed. Perspective Understanding Covid Vaccine Efficacy over Time I.Tan and Othersĭata from Singapore on BNT162b2 vaccination in children 5 to 11 years of age showed that during a period of omicron-variant predominance, BNT162b2 reduced the risks of SARS-CoV-2 infection and Covid-19–related hospitalization. Original Article BNT162b2 Protection against Omicron in Children S.H.X.However, heterologous boosting and a longer interval between doses resulted in higher neutralization levels. In this study, neutralization against the SARS-CoV-2 omicron subvariants was reduced with both the inactivated and ZF2001 vaccines.
